Best Wet Cat Food For Weight Loss

Last Updated on November 7, 2022 by

There are a number of reasons it’s important to keep your cat at a healthy weight. Overweight cats tend to experience a number of health problems, such as diabetes and heart disease like coronary artery disease. To avoid having to pay for veterinary care for your cat later down the road, consider trying a wet cat food option that’s designed for weight loss. In this article, we’ll discuss what you should consider when picking the best food for your chubby cat.

Have you ever noticed that your cat’s food doesn’t seem to stay on her body? Fortunately, you have the internet and you can use it to find the best cat weight loss foods.

One of the most frequent questions we get asked as cat and dog owners is about which pet food will help our pets lose weight without having to go on a diet plan. While we like our pets, we all know they can be quite gluttonous little creatures that require plenty of exercise.

Best Wet Cat Food For Weight Loss

Just like us humans, cats love their food—sometimes too much. Combine that with the life of leisure that many of our beloved house cats live (like sunbathing in their favorite chair for hours), and sometimes, your food-motivated cat starts to pack on the pounds, which isn’t healthy.

Almost 60 percent of cats in the United States are considered overweight or obese (1), which makes them prone to a variety of health issues. “Excess weight causes increased inflammation in a cat’s body,” explains TB Thompson, a veterinarian from Phoenix, Arizona. “It can cause or worsen problems like osteoarthritis, asthma, heart disease, diabetes mellitus, pancreatitis, kidney disease, and fatty liver.”

Diets aren’t easy for anyone, even Fluffy—but the food you feed your cat can definitely make a difference.

Weight Loss Cat Food: What to Know
Cat eating food from bowl
If your cat needs to lose weight, you may think it’s simply a matter of feeding less of your cat’s normal food. Portion size does play a big role—if you give your cat too much food, he might overeat and gain weight. However, if you are feeding the recommended amount and start cutting back on regular portions, you could be depriving your cat of essential nutrients.

To avoid nutritional deficiencies, your veterinarian may recommend switching your cat to a food that’s been specially formulated for weight loss or weight control. “Weight loss cat food can help your cat lose weight successfully without compromising balanced nutrition and without making your cat super hungry all the time,” says Thompson.

You can also look for cat food that’s labeled as “weight control” or “weight maintenance.” While these foods might have a slightly higher calorie content than “weight loss” labeled foods (and are not necessarily aimed at weight loss), they’re still on the lower side in terms of calories and can still help your kitty shed some excess pounds, Thompson explains.

Once your cat starts to lose the excess pounds, you might also see his health improve as a whole. You might notice that he is more energetic and playful, or that he spends more time around you (rather than sleeping). This also has another added benefit: if your cat is more active overall, it will be easier for you to notice when he is not feeling well.

Keep in mind that it is unhealthy for your cat to lose too much weight in a short period of time. As a general rule, cats can safely lose about 0.5-2 percent of their body weight per week, which comes to about 4 ounces per week for a 20-pound cat (2).

Is Wet or Dry Food Better for Overweight Cats?

Your cat can lose weight on wet or dry food—it really depends on the cat and what kind of food he prefers.

Wet food has a lot of extra moisture, which makes it less calorically dense even though the portion might be bigger. This can help your cat feel full sooner, even if he ate fewer calories.

“I’ve definitely had cat patients who have done better with wet weight loss cat food because it kept them feeling more satisfied,” says Thompson. “But even cats who refuse to eat wet food altogether can lose weight with the right dry food and diligent monitoring.”

Weight Loss Cat Food Brands: What to Look For

When choosing a weight loss cat food, the smartest move you can make is to read the label carefully. “Make sure the food is labeled as complete and balanced,” Thompson says, to ensure it has the nutrients, vitamins, minerals, fats, and other supplements your cat needs to stay healthy.

Here are some other details veterinarians like Thompson recommend paying attention to:

Calories
“Some supposed weight loss foods have just as many calories as average cat food,” says Thompson, while other foods not labeled specifically for weight loss are great choices.

The goal is to make sure the food you choose has fewer calories per cup than the one your cat is currently eating. Your cat will only lose weight if there is an overall caloric deficit.

Protein vs. Carbohydrate Content

Cats are true carnivores and natural hunters, so they generally do well when they eat food that’s high in protein. It can also help preserve their muscle mass while they’re trying to lose weight.

Look for food that lists protein as the first ingredient and be wary of foods that have too many carbohydrates as the first several ingredients. It’s okay for there to be some carbs, though, as this gives the food fiber, the next thing to look for.

Fiber
Fiber helps your cat feel full, even if he ingests fewer calories. Look for foods with increased soluble and insoluble fiber, Thompson says. This fiber will generally come from healthy carbohydrates, such as sweet potato, pumpkin, or brown rice.

Avoid Fillers
Some foods will have a lot of low-cost ingredients in them that have little nutritional value and aren’t as healthy for your cat. These include animal by-products, grain products, and corn or wheat gluten.

How to Help Your Cat Lose Weight: Tips and Advice
Cat playing with cat toy on the ground
In addition to feeding your cat the right food to support his weight loss, you can also help him lose weight some other ways too:

Encourage regular, low-impact exercise. Encourage your cat to play with a new toy or an interactive toy, such as a feather wand. “Increasing activity will improve your cat’s mental attitude as well as burn a few more calories,” says Thompson.

Cut back on the treats. We’ve all been there: your hungry, purring kitty hops up on your desk and gives you that wide-eyed, pleading look that screams “treats please.” It’s hard to resist, but it’s in his best interest if you keep the treats to one or two small ones a day.

Stick to portions. Make sure you feed your cat the portion recommended by your veterinarian or the packaging and not more.

If you’re unsure what food to get your cat—or if your cat is having trouble losing weight even on a weight loss cat food—talk to your vet, especially if your cat is severely overweight or if you aren’t seeing a slow, gradual decrease in weight after 6-8 weeks, Thompson says.

“[Your] vet can recommend a special diet with a controlled calorie content that will increase your cat’s chances of success in losing weight,” says Thompson. “It’s rare that we can’t figure out a way to safely reduce a cat’s weight but sometimes it takes ingenuity. Don’t give up.”
