The calorie count is 416, which the fat most likely increases. The principal sources of meat and fat are chicken and eggs.

If you want the best in personalized nutrition, Royal Canin Weight Care Dry Cat Food is a fantastic choice. This product gets high marks for its protein content, which is 34%.

Chicken has both protein and fat. We loved that it didn’t have any filler components. It’s simply a well-balanced, very nutritious diet.

Some pet owners may like the addition of rosemary, citric acid, and tocopherols to the food to keep it fresh. It contains psyllium seed husk, which is a good source of fiber.

The cuisine costs more than comparable options. We’d forgive that if the calorie count per cup was more than 255. It is available in 3, 6, and 14-pound bags.

In terms of high-end options, we believe this is the best high-calorie cat food for weight gain.

On the negative side, the cat food is pricey, especially in 2.9-ounce cans. To maintain the weight of a 10-pound cat, you must also feed your pet 4 14 cans.

Wellness CORE Natural Grain-Free Canned Cat Food is a pate-like diet that is high in protein sources including turkey and chicken.

The calorie count per can is reasonable at 101. It also contains a variety of fatty acid sources, such as salmon oil and flaxseed.

We liked that this weight gain cat food comes in 3- or 5.5-ounce cans. However, it is costly, given that an adult need two meals every day.

  • USA-made


  • Ingredients for fluff
  • Expensive

How to Choose the Best High-Calorie Cat Food for Weight Gain

Weight loss, especially if unexplained, can be harmful and even fatal to your pet. It can be caused by a variety of factors, ranging from intestinal parasites to more serious medical issues.

The former is one of the reasons we advise keeping your cat indoors. Many parasites, including pinworms, are carried by rodents.

A healthy adult cat requires approximately 240 calories. Several factors can have an impact on the bottom line, including:

  • Age
  • Status of reproduction
  • Levels of activity
  • Health

The most important thing to remember is that the feeding guide on the back of the bag or can is just that: a guide.

You and your veterinarian must decide whether your pet’s diet requires an increase in calories. To decide which products pass approval, start with the label. You must learn the following things:

  • Stage of life
  • Analysis of nutrients
  • Calories
  • Ingredients
  • Nutritional compliance according to the Association of American Feed Control Officials (AAFCO)

Let’s go over each one in depth.

Life Stage of a Cat

Like dogs, the nutritional demands of kittens and cats fluctuate with age and life stage, but not significantly. However, it is sufficient to distinguish between a healthy and unhealthy pet.

As a result, we advocate keeping with the proper product even if it is just to reduce the danger of obesity in pets that are at their ideal weight.

Nutrient Analysis of Cat Food

The nutritional analysis is the point at which the petal meets the metal. The most important thing to remember is that cats are obligate carnivores who acquire the majority of their nutrition from meat.

Kittens must consume at least 30% protein. Adults require 26%. Of course, your pet may consume grass or catnip on occasion.

The cat food you feed must be nutrient-complete and balanced in the proper quantities. Cats, unlike dogs, cannot produce vitamins A or B3 (niacin).

That has to do with what you put in their dish. Cats would receive these nutrients from their prey, mainly rodents, in the wild. You can use the guaranteed analysis on the bag or can to help you choose a product.

Kittens, for example, require 9,000 IU/kg of vitamin A and 60 mg/kg of niacin, which should be considered while looking for a high calorie kitten food.

Adults must receive 5,000 and 60 points, respectively. Arachidonic fatty acid and taurine must also be included in cat diet. The amounts or percentages of these vital nutrients will be provided in high-quality products.

Calories in Cat Food

Based on her bodily state, you can determine whether your cat requires food for weight gain. An underweight cat has minimal fat around her ribs, which makes them easier to feel.

You might detect them as well if you stroke her back. The Pet Nutrition Alliance has a helpful calculator that you may use to estimate your feline’s daily caloric intake, even by food brand.

We recommend that you collaborate closely with your veterinarian to ensure that your pet is gaining weight in a healthy manner. Less is sometimes more.

The last thing you need is a vomiting cat because she ate too much, too quickly. Slow and methodical weight loss is the best technique to give her delicate body time to acclimatize.

Ingredients in Cat Food

The ingredients on the bag or can must be listed in order of weight, from most to least. Because protein is so important, we prefer goods that include it first.

However, don’t be alarmed by the phrase “byproducts.” They are safe to use to meet your pet’s nutritional needs, according to the AAFCO. We agree that it is a more environmentally friendly option than wasting food.

Organ meats are a fantastic source of nourishment. They frequently include higher protein levels for a balanced diet. There are also some items that include numerous types of meals.

These are concentrated meats or bones that have been rendered safe for your pet by the producer. The nutritional balance of these components is subject to stringent restrictions.

Many so-called boutique companies will include people items on their ingredient list, such as blueberries and peas. You might also come across things labeled “human-grade.”

These are basically advertisements. Foods near the bottom of the list are frequently insignificant. The pet industry is very aware of how some pet owners perceive their pets and will market their products accordingly.

AAFCO Conformity

The best pet foods will include a declaration stating that they meet the AAFCO’s nutrient profiles for the species and life stage.

That is what you want to see on whatever product you purchase. That way, you can be sure it has the perfect combination in the exact proportions for maximum nourishment. Remember that this information only relates to diets, not treats.

A product’s name is held to the same standards. If it says “all-chicken,” it is exactly that. If it contains ingredients, it must contain 95% of the list.

This rule applies if a company employs a flowery name, such as chik’n. You may come across cat food labeled “Kitty’s Fish Delight.” AAFCO requires it to be at least 25% of the product’s weight, excluding water.


According to our reviews, the Smalls Freeze Dried Raw Bird Recipe is the finest cat food for weight gain overall.

If you want to put some weight on your cat, this could be a fantastic option for you. The protein source is primarily chicken. This human quality dry food will be devoured by your feline.

Iams ProActive Health Kitten Dry Cat Food outperforms on multiple fronts. It may be fed to pets at various stages of development, making it an even better buy.

It’s also gentle on your child’s digestive tract. With this product, Iams knocked it out of the park.

Choosing the correct diet for your cat is a serious effort, especially if she suffers from a medical condition that affects her weight.

Every pet owner’s goal is presumably to find something she enjoys that also delivers adequate nutrients.

BestForPets (bestforpets.org) hopes this best cat foods for weight gain (high calorie) list has helped you choose the perfect one for your kitty BFF.
