In choosing products to test, we prioritized meat-centric formulas for cats in various life stages with different needs and preferences. All products were purchased at full retail price and evaluated in-depth. Our cats provided input on the foods’ flavor and general appeal while I analyzed the product information to determine its nutritional adequacy. We also researched the brands to assess their trustworthiness and rate of customer satisfaction.

What Is the Best Cat Food for Weight Gain?
Chiefly, the best cat food for weight gain is one that helps to address the root of your cat’s weight problem.
Again, your cat’s unique situation dictates their dietary needs.
Generally speaking, an abnormally low weight is the result of either a poor appetite, mouth problems, or a condition that’s preventing the cat from maintaining a healthy weight. The latter category includes intestinal worms or a thyroid condition like hyperthyroidism.
In most cases, this means that the best cat foods for weight gain provide a combination of palatability and calorie density.
Remember that senior cats need high-quality protein to prevent muscle wasting.
Senior cats, with their tendency to lose muscle mass and become “skinny old cats”, are usually the first group to require food for weight gain. It was once recommended that senior cats eat low-protein diets due to a possible connection between excessive protein and the kidney failure experienced by so many senior cats.
More current research, however, indicates that a diet rich in high-quality animal protein can help prevent sarcopenia of aging – the muscle wasting associated with old age. Cats are still obligate carnivores, so animal-based protein is an essential part of your cat’s diet, regardless of his weight.

If your cat has a poor appetite, choose foods and supplements that help to rev up their desire to eat.
It’s terrifying to watch your cat refuse meal after meal. Because it’s so important to ensure that your cat continues to take in sustenance, you’ll need to think creatively to encourage your cat to eat.
Here are a few foods, food toppers, and supplements that have a history of encouraging picky cats to eat.
- Bonito flakes
- Bone broth
- Duck fat
- Unseasoned chicken, turkey, or beef baby food
- Chunks of raw or cooked unseasoned meat
- Canned sardines packed in water
- Canned tuna packed in water
The following are calorie-dense diet supplements that help your cat take in calories without spending much time at the food bowl:
- Egg yolks
- Purina Fortiflora Feline Nutritional Supplement
- Wysong PDG Canine/Feline Food Supplement
- Tomlyn Nutri-Cal For Cats

Don’t think that because it’s calorie-dense, dry cat food is necessarily the best cat food for weight gain in adult cats.
Although many cats find dry food highly palatable and it is often more calorie-dense than wet food, it’s not always the best choice for weight gain.
First and foremost, dry cat food doesn’t offer the moisture your cat requires to stay healthy and hydrated. If you choose a dry food diet for your cat, you’ll need to supplement their moisture intake in other ways.
Second, dry cat food isn’t ideal for seniors and other cats with poor dental health. If your cat has lost weight due to oral pain or other dental issues, dry kibble may only exacerbate the problem.
Finally, commercial dry food is more likely than wet cat food to contain protein sources that are not species-appropriate for cats – things like pea protein and corn gluten meal rather than whole animal proteins.
All this said, if the only thing your cat will eat is dry food, quality options do exist. Look for a high-protein, low-carbohydrate recipe with a short list of ingredients and no artificial additives.
If your cat isn’t picky, wet cat food or even freeze-dried raw food might be the best option for weight gain. These foods tend to be more carnivore-appropriate and higher in moisture than the average commercial dry food. You’ll still have to pay attention, however, to things like carb content and caloric density.

Additional Tips for Managing Your Cat’s Weight
If you’re looking to help your cat gain weight, it’s important to focus on their overall health and well-being. Here are some tips that I’ve found helpful for managing a cat’s weight while addressing any underlying issues that might be causing weight loss.
Meal Frequency
Cats with a low appetite or those needing to gain weight may benefit from more frequent, smaller meals throughout the day. This helps increase overall caloric intake without overwhelming the cat at once, which can be especially beneficial for those who are reluctant eaters[1].
Ruling Out Medical Conditions
Any significant or unexplained weight loss in a cat should always be investigated by a veterinarian. Conditions like hyperthyroidism, diabetes, or gastrointestinal disorders[2] can lead to weight loss and require medical treatment. A proper diagnosis ensures that underlying health problems are addressed before adjusting the cat’s diet for weight gain.
Mental Stimulation
Stress and boredom can contribute to a poor appetite, so it’s important to create an enriching environment for your cat. Interactive toys, puzzle feeders, and regular playtime can reduce stress and help stabilize weight loss by promoting a healthy appetite and improving overall well-being[3].
