Are diet cat foods really worth it?

FeaturedFood & DrinkLifestyle

Written by:


The average cat should have a healthy body fat percentage of 5-10%. This is measured by measuring the girth at its widest part, usually around the loin, and comparing it to its length. If a cat has a body fat percentage that is too low or too high, this can lead to health issues including heart disease, diabetes, and cancer.

Many people aren’t aware that there are specific weight guidelines for cats as well as humans. A healthy cat should be slim but fit: they should have good muscle tone without being overweight or underweight. It’s important that you don’t feed your cat too many treats because those will contribute to their overall weight gain (or loss in the case of underweight cats).

Why My Cat Should Lose Weight?

With proper care, your cat is likely to live a long and healthy life. However, obesity has become a significant problem for cats in the U.S., with over 50 percent of cats being overweight or obese.

Obesity is defined as having more than 10% body fat or an excess accumulation of adipose tissue (fat) on the body, which can lead to health problems such as diabetes, hypertension (high blood pressure), heart disease, and osteoarthritis. In addition to these risks, obesity can also make it harder for your cat to move around and enjoy their daily activities in the same way they did before they gained weight.


Beneficial Supplements of Diet Cat Foods

If you are considering purchasing a diet of cat food, there are many benefits to consider. These foods can help fight the most common cat diseases such as kidney disease and diabetes.

Additionally, diet cat foods contain beneficial supplements that will keep your cat healthy and happy. These include vitamins and minerals, probiotics, prebiotics, omega fatty acids, chondroitin sulfate (which can help heal damaged joints), glucosamine (a building block of cartilage in cats’ bodies), fish oil (to help reduce inflammation), flaxseed oil (for omega-3 fatty acids), l-carnitine/taurine combination supplement (to support heart health).

What are the Health Risks of Obesity in Cats?

Obesity is a serious health risk for cats. According to the American Veterinary Medical Association, obesity has become an epidemic in cats and can lead to diabetes, heart disease, and arthritis. These diseases are often fatal if left untreated. Additionally, obese cats may experience complications during pregnancy or delivery due to their weight.

Obesity has also been linked to joint pain and arthritis among felines. Arthritis is very common in cats—it’s estimated that up to 50% of all kitties suffer from it at some point in their lives. The physical stress on joints caused by excess weight puts even more demands on already-weakened cartilage tissue resulting in painful inflammation.

Selecting Weight and Diet Management Food for Your Cat

When choosing a cat food that meets your feline’s needs and your budget, there are several factors to consider. The first is the type of diet that’s best for your cat. Is it high in protein? Low-calorie? High in fiber? How much water content does it have? These questions will help you determine what type of diet management food is right for your pet.

Next, consider how much time and money you want to spend on feeding him. If he’s not eating enough calories or protein or if he has certain health problems like diabetes or kidney disease, then clearly he’ll need more care than usual—but if his health isn’t an issue (yet), then chances are he won’t need as much supervision when it comes time to eat dinner each day.

How Does Diet Cat Foods Work?

Diet cat foods work by controlling your feline friend’s calorie intake by limiting their daily diet to a few hundred calories per day. This allows your cat to maintain a healthy weight despite being on a restricted diet, which is especially important for overweight or obese cats. Additionally, most diets also control the number of carbohydrates in their food as well as fat content, which helps keep your pet’s blood sugar levels balanced and prevents them from gaining too much weight.

The best part about these types of foods is that they’re affordable! They have been specifically designed with “weight management” in mind so you don’t have to worry about spending an arm and leg just trying to get your cat back into shape again after months (or even years) of overeating.

Cat’s Nutritional Needs When on Diet Food

The right diet can help your cat live a longer, healthier life. Diet foods are often regarded as a high-quality option for cats who need to lose weight or control their diabetes. However, they can also be helpful for healthy cats who want to maintain a healthy weight.

When choosing a diet food, it’s important that you look at the ingredients and make sure they’re appropriate for your pet’s age and health status. You’ll find that some diets include higher amounts of protein, fiber, fat, and/or calories than others; this means that if your cat is getting older or has certain medical conditions (such as kidney disease), then you’ll want to choose something with fewer nutrients in it because these may cause more harm than good!

How Many Calories Should My Cat Eat Per Day?

If you’re feeding your cat a diet from a can or bag, the label will have information about how many calories are in each serving. If you’ve decided to make your own food, then this is something that you need to keep in mind.

It may seem like a simple question: “How many calories should my cat eat per day?” But there are actually several factors at play when it comes to determining how much your feline should consume.

  • Age – The more active and older they get, the more calories they’ll need. Cats who are overweight or obese should also be eating fewer calories than normal cats of the same age and weight (if possible).
  • Weight – It’s true that kittens have special requirements for nutrients such as calcium and protein compared with adults; however, once felines reach adulthood their nutritional requirements remain mostly unchanged regardless of whether they’re lean or chubby kitties!
  • Activity level – A sedentary lifestyle won’t require as many daily kilocalories as one filled with plenty of playtime outside (or other physical activity). However, if an indoor pet gets lots of exercise by running around inside its house all day every day then they might require extra energy too!

Tips for Helping Your Cat Lose Weight

  • Feed your cat smaller portions. Because a feline’s metabolism is about twice as fast as that of humans, it takes more food for them to burn than us. This means that if you feed the same amount of food to both species, a cat will gain weight faster than you and vice versa. So while it may seem counterintuitive at first, it’s actually better to feed your cat smaller meals throughout the day rather than one large meal once or twice per day.
  • Feed your cat more often. The reason why feeding cats multiple times throughout the day works so well is because they’re constantly burning energy; therefore you don’t have to worry about overfeeding them too much at once (or getting them into bad eating habits). Plus, this allows for more vitamins and minerals—which are critical for healthy growth! If possible try giving wet food in addition since this has slightly fewer calories per serving compared with dry foods; however make sure there isn’t any added salt or sugar before giving either type of product because these can cause weight gain instead of reducing it.”

How Long Should my Cat be on Diet?

There’s no hard-and-fast rule for how long your cat should be on diet cat food. The answer depends largely on the individual cat and its needs. Some cats will lose weight more quickly than others, while others will need to remain on the diet food for life.

The most important thing to remember is that if your cat has lost weight while eating diet food, you should keep him or her on it until he or she has reached a healthy weight. If you stop feeding the diet too soon, your pet could gain back the weight along with all of those unwanted pounds!

Does Age Matter in Feeding Diet Food For Cats?

As your cat ages, it is important to adjust the amount of food you feed him or her. Older cats may have less energy and be less active, so they need fewer calories. Younger cats may require more calories because they are growing fast and have a higher metabolism. To determine how much to feed your cat, you can use our handy chart below:

  • Under 10 pounds – 1/2 cup per day
  • 10-20 pounds – 1 cup per day
  • 20-30 pounds – 2 cups per day
  • 30+ pounds – 3 cups per day

If your pet still seems hungry after eating this amount of diet food for cats then try adding an additional tablespoon each week until he/she seems satisfied with their portion size (remember, a healthy weight is important for both dogs and cats).

The Best Diet Cat Foods According to Veterinarians

Low-calorie diets are often recommended for overweight cats. In general, your veterinarian should be able to recommend a diet that will help your cat lose weight safely and effectively.

The best low-calorie diets contain high levels of protein, fiber, and nutrients to make sure that they can fulfill the dietary needs of cats while still providing fewer calories than normal foods. While most owners would prefer to give their feline companions a treat every once in a while, it’s important not to overindulge them with these kinds of foods because they may end up eating too much fat or carbs from other sources that could cause negative health effects down the road (such as diabetes).


Making sure that your cat is at a healthy weight is an important part of caring for him. Diet cat foods also help to manage diabetes and other diseases that may be linked to obesity. There are many different brands of these foods on the market, so we recommend consulting with your veterinarian before making a purchase decision.

How to find the best quality wet cat foods


There are a few key things you should always look out for when choosing canned cat food. First and foremost, we care about cat health – and one of the most important things for keeping kitty healthy is whether the cat diet is preventing illness and disease.

  • Check the fat and protein content—cats need lots of both.
  • Avoid foods that contain by-products or too many carbs.
  • Keep an eye out for artificial colors, flavors, or preservatives.
  • Some of the best canned cat foods are formulated with omega fatty acids in the form of fish oil to help protect the heart.
  • Look for the right vitamin and mineral content, and focus on wet cat food brands that you trust.

Whenever possible, shop at pet boutiques and local stores so you can ask questions about the ingredients in their products.

When choosing a wet cat food for your senior cat, remember to look for a wet cat food that has a higher protein content along with a lower carbohydrate content. Not only does it need to be high in protein, but you will also want to make sure that the protein is coming from high-quality sources such as chicken, turkey, or fish. You also want to avoid artificial colors and flavors and byproducts. If you are searching for the best healthy cat food for your senior kitty, consider one of these three options below:

  • Instinct by Nature’s Variety Grain-Free Wet Food
  • Weruva Best Feline Friend (BFF) Pouch Cat Food
  • Nutro Max Gourmet Chicken Paté With Natural Chicken Liver

The best wet cat food for kittens is holistic, grain-free, and made with natural ingredients. Before serving wet food to your kitten, make sure that you follow the instructions on the packaging. Some brands of wet cat food should be mixed with water before being served.




For cats with sensitive stomachs, these options are all highly recommended.

  • Hill’s Science Diet Adult Sensitive Stomach & Skin: This formula from Hill’s Science Diet is very well-rated, and it’s one of the best cat food for hairballs available. It does have grains in its ingredients list, but that’s a common problem for many wet cat foods. It has no artificial colors or flavors.
  • Purina Pro Plan Sensitive Skin & Stomach: Purina has been a pet food powerhouse for decades, and this wet cat food formula is no exception. The sensitive skin & stomach option boasts real turkey as its first ingredient and includes brown rice and oatmeal as well. In addition to being great for cats with sensitive stomachs, it can also be effective against allergies and may help reduce itching and scratching associated with sensitivity problems.
  • Blue Buffalo Natural Veterinary Diet GI Gastrointestinal Support: This product from Blue Buffalo is designed specifically to help address digestive health concerns in felines. That means your kitty will get plenty of nutrition and hydration while getting their GI tract back on track. In fact, it’s the top suggested product by veterinarians when it comes to resolving gastrointestinal issues like vomiting or diarrhea in your furry friend! Its ingredients include wholesome chicken along with pumpkin, flaxseed oil (for omega-3 fatty acids), sweet potatoes (for vitamin A), cranberries (for antioxidants) – plus other healthy fruits/vegetables/oils which provide vitamins/minerals needed every day.




Cats are carnivores. Unlike dogs, cats aren’t omnivores and don’t eat meat just because it’s readily available, they need meat in their diet to survive and thrive.

Meat has two main components: protein and fat. While there are some essential nutrients in carbohydrates (namely fiber), cats can go without them as long as they have plenty of protein and fat in their diet.

Cats need more protein than dogs. Dogs can subsist on diets of 7-10% protein, but cats need double that: 14% is the minimum for a healthy cat, though 18% or higher should be the goal if your cat is on the hunt for weight loss. This is even more than humans require – we only need 10-15%. *

Fat is an essential part of a cat’s diet. Though it’s tempting to put them on low-fat diets like we might do with ourselves or with our overweight pooches, most experts agree that restricting fat below 10% can cause serious health problems for your feline foodie. You see, fat isn’t something that cats eat just because it tastes good (though they certainly seem to think so!). Rather, it’s their most important source of energy!

You can help your purebred cat reach his full health potential by choosing an adult wet cat food that meets his unique needs. Purebred cats are predisposed to certain diseases and health conditions, so it’s important to ensure your cat is getting the nutrients he needs for optimal wellness.

How are purebred cats different from mixed breed cats?

Purebred cats are bred for specific characteristics and traits, whether it be a thick coat of fur or a specific eye color. This can lead to certain health issues in these breeds, like heart problems in Maine Coon cats and urinary tract issues in Russian Blue cats.

How do I choose the right canned food for my purebred cat?

When you’re comparing options, look for: A complete diet that addresses your cat’s most common breed-specific concerns; 100% complete nutrition with essential vitamins and minerals like taurine; No artificial additives or fillers; Special formulas designed specifically for adult or senior purebreds




Protein is an especially important nutrient for cats. Unlike humans and some other animals, they are not able to create the amino acids they need in order to produce protein. This makes it essential that cats get sufficient amounts of protein from the food they eat. Kittens and senior cats have especially high protein requirements, so if you own a cat who falls into one of these categories, be sure to look for foods containing extra protein.

Some common examples of high-quality, high-protein canned wet food include:

  • Hill’s Prescription Diet y/d Dry Cat Food
  • Blue Wilderness High Protein Grain Free Adult Dry Cat Food
  • Purina Pro Plan Savor Adult Shredded Blend Chicken & Rice Formula Dry Cat Food


As your cat ages, his metabolism will slow down, meaning that he’ll need fewer calories to maintain his weight. But when you have a cat who is already overweight or obese, it can be tricky to figure out what to feed them — because you don’t want to under-feed them or accidentally starve them. You also want to make sure the food is healthy and nutritious.

The best foods for weight loss or weight management are those that are high in protein and low in carbohydrates and fat. It’s also important to bulk up on canned food (which is higher in water content) rather than feeding dry foods, since they tend to be very calorically dense—and fillers like corn and soy can cause inflammation as well as weight gain. Finally, avoid any foods with artificial colors or flavors; instead try looking for limited ingredient diets (LIDs).


At first glance, it may seem like human-grade cat food is unnecessary and that you can give your cat any kind of dry or wet food readily available at the supermarket or pet store. There’s nothing wrong with using those foods either; they provide all of the essential nutrients cats need to maintain their health in addition to making kitty feel more comfortable in your home.


The problem arises when you consider what might be in them: preservatives such as BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), ethoxyquin, polysorbate 80, sodium metabisulfite, propylene glycol alginate among others. These chemicals are safe for human consumption but could pose a threat if ingested by cats—especially if stored for an extended period of time (such as canned food).


Human-grade cat food is produced by companies who go above and beyond making sure their ingredients are free of toxins while still being tasty enough for kitty’s taste buds.


So what exactly determines whether a given brand is actually “human grade”? Below are some key indicators:


The entire ingredient list should be visible on the package. No ingredients should be abbreviated or disguised under different chemical names just because they sound similar. For example if it says “corn gluten meal” on the label instead of just “corn,” don’t buy it because there’s no guarantee that this ingredient will not contain any corn gluten meal derived from corn gluten or other grains.

Raw food is a great choice for cats with food allergies. Just like humans, some cats can be allergic to certain foods, and the best way to determine what exactly your cat is allergic to is by feeding them raw food. The reason for this is because raw food doesn’t contain any additives or preservatives that could potentially trigger an allergic reaction in your cat. If you’re feeding your cat dry kibble and they have an allergy problem that a vet hasn’t been able to diagnose yet, it may very well be due to an ingredient in their kibble that they aren’t naturally predisposed to eating.


Raw food also works wonders for sensitive stomachs. Because it contains only natural ingredients and avoids using any fillers or additives, raw food is much easier on a cat’s stomach than wet or dry kibble (which are typically packed full of unnecessary fillers). In addition, if your cat has a sensitive stomach then they probably don’t want too many different flavors mixed into their diet – so feeding them only meats will help keep their diets simple while still providing all the nutrients needed for healthy weight gain/loss.


However, be aware that raw diets can pose health risks. Check with your vet.

Open Farm Rustic Blend Wet Cat Food is a chicken-based wet cat food using a moderate amount of named meats and by-products as its main sources of animal protein, thus being somewhat lower quality than some other options.


Reviewers love that this food contains no fish, making it a good option for cats with allergies. It also has a high protein content, as well as B vitamins to support a healthy coat. Tiki Cat uses human-grade ingredients, and the formula includes taurine to help your cat’s eyes and heart stay healthy. Each can has between two and three servings in it, but because of the quality of the ingredients used, you can feed half a can per day instead of one whole one—so keep in mind that a 12-pack will actually last for up to 24 days.


Royal Canin is a trusted brand that provides formulas for both kittens and adult cats. This particular product has a wet food formula specifically designed to meet the nutritional needs of growing kittens, as well as to support brain development. The fact that your cat will love it doesn’t hurt either.


This canned kitten food is fortified with DHA, which is an omega-3 fatty acid commonly found in fish oil and often added to baby formula in order to promote healthy brain development. It also contains prebiotics for digestive health, chicken by-product meal for protein, and fish oil for skin and coat.

The crude protein content is 34 percent while the crude fat content measures 20 percent. The rest consists of water (max 10 percent), ash (max 5 percent), dietary fiber (max 1 percent), moisture (max 78 percent), calcium (min 0.55 percent), phosphorus (min 0.45 percent) and taurine (min 0.1%).


Blue Buffalo offers a cat food with human grade ingredients, free of by-products, corn, soy, and wheat. It doesn’t contain gluten or grains. Blue Buffalo sources all its ingredients from the US and produces its products in the US as well.


The brand is named after a “beloved” dog owned by one of the founders who died of cancer. The owners wanted to create a pet food that didn’t use by-products or fillers like corn and wheat gluten which they believe were responsible for his death.


Weruva Mideast Feast is a pate, not a stew, so if your kitty isn’t a fan of pates or pureed foods, you may want to find another choice. It’s high in protein (8.3%) and contains carbs (2.1%), but the carbohydrates are from peas, pumpkin and potato starch.


There are no grains in this food, so it’s good for cats with allergies to corn or other grains. It’s also a low-ash formula (less than 1 percent), which makes it ideal for cats with urinary tract issues. However, Weruva is high in fat (5 percent), and some cats don’t do well on high-fat diets, so that may be an issue for your cat as well as the fact that most cats don’t like the fishy taste of this food.


Wet cat food is usually made with more meat than dry cat food. As a result, wet cat food provides more moisture and protein to your kitty, making it the best option for cats who have dental or kidney issues. However, this comes with a few downsides: wet cat food is more expensive and can be messy. In addition, wet cat food isn’t as filling as dry cat food due to its lower fiber content. For these reasons, if your kitty doesn’t have health issues that require him to eat wet food, you should consider choosing a high quality dry cat food instead.




Knowing exactly how much wet food to feed a cat can be challenging. The amount of wet food that should be fed to a cat will vary depending on the size, age and activity level of the cat.


In general, most cats need between 200-250 calories per day.




If you’re like me, then you always wonder: “What’s best for my cat?” In this case, wet food has the edge over dry because it contains the most water. Most cats don’t drink enough water on their own, so giving them a diet rich in wet food ensures that they are getting enough hydration. It also has more protein and less carbohydrates than dry food, which is better for your cat’s digestive system. Wet food is also more palatable and therefore easier to serve to your cat, but remember that it’s usually more expensive and needs to be refrigerated.




The Internet is chock full of information about the healthiest cat food, but choosing the right one can be daunting. There are many factors to consider when deciding what you should feed your cats. Knowing the healthiest wet cat food will help you decide which brand is best for them.


The most important aspect of feeding your cat is knowing how long their food should be cooked or cooked and refrigerated before serving.


Cooked and Refrigerated: This is just what it sounds like; this type of food has been cooked (boiled) and subsequently cooled so that it does not need to be refrigerated. This means that it keeps for at least 2 hours, although in a heat wave, you might not want to let it sit out overnight as there’s a chance it could spoil before then.

Once opened, wet cat food doesn’t need to be refrigerated, as long as you’re going to finish it within a few hours. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), wet cat food is fine at room temperature for up to two hours, whether or not it’s been opened. If you don’t plan on finishing your pet’s meal in that time frame, stick it in the fridge instead. If you don’t finish an opened bag of wet food within two weeks, throw out what’s left. Similarly, if you don’t finish an opened can of wet food within three days, throw out what’s leftover.




Yes. It’s perfectly fine to freeze wet cat food. You can freeze opened cans and unopened cans of wet cat food, but we recommend freezing the opened cans since you don’t want your cat to eat from an unopened can that has already gone bad. Keep in mind that unopened cans don’t last very long in the fridge once they are thawed out. Make sure to label your frozen foods and check for any freezer burn before feeding it to your cat.




Once your frozen can of wet cat food is ready to be used, place it in the refrigerator overnight or try one of the following: running warm water over the can, placing it in a bowl of warm water, or leaving it on a counter at room temperature until thawed out completely.

Leftover canned foods should be put back into their original packaging and placed inside an airtight container; then put them in the refrigerator or freezer right away if they haven’t been used up within 24 hours after opening them up initially. Unused portions of canned foods should not be kept out at all times like dry foods because they could go bad sooner than dry foods would due to high moisture content and susceptibility towards bacterial contamination from unclean surfaces (e.g., pet bowls).




You should never mix water with dry cat food. Dry cat food is already about ten percent water, and adding more can cause your cat to get dehydrated. Adding too much water to dry cat food may also cause it to expand and make your cat feel bloated. Dehydration can be very dangerous for cats, and cause kidney failure or other serious health problems, so be sure not to add water.

However, you should serve wet cat food with a little bit of extra warm water added on top if your cat has urinary tract disease or kidney disease. Although this seems counterintuitive at first—why would you give a sick cat more water?—it actually forces him drink more in order to get the extra moisture he needs. If you feed your cat canned food as his only source of nutrition, then you don’t need to add any additional water unless he has renal issues that require it.

Wet food is generally more expensive than dry, but because cats on wet diets get more moisture and less carbs, you can feed them smaller amounts of food to meet their daily needs. If you’re switching your cat from dry to wet food, or if they’re used to eating only a few bits of kibble at a time, offer them smaller portions than recommended on the package.

For your average fully grown cat who weighs between nine and thirteen pounds, aim for two ½-cup servings of wet food every day. Though wet food has fewer carbohydrates per serving than dry kibble, it also doesn’t have as many calories. If your cat is overweight or obese, consult with your veterinarian so that you can develop a weight loss plan that keeps her full but in shape.




Consider what each wet cat food’s ingredient panel has to offer, and consult your veterinarian for advice or concerns. You know you want a healthy diet for your cat, but do you want to take advantage of the health benefits of raw and grain-free foods? Are you willing to pay more upfront for those benefits? Do you have a brand that you trust? Finally, how important is convenience in feeding time? All these factors will affect your choice—and no matter which one you choose, your cat is guaranteed a healthier diet than the cheap canned food from 10 years ago.
