How to get a cat fat with a calorie surplus diet

It seems easy enough to feed your cat more calories than they burn when following a calorie surplus diet, but it’s not really that easy. Any high-calorie feline diet requires careful consideration of where the calories are coming from. Three nutrients are available to cats as food sources, as shown in the table below:


Calories per gram







Because of their carnivorous nature, cats are skilled at processing calories from proteins and fats rather than carbohydrates. Due to their shorter digestive tracts than those of herbivores and omnivores, cats should only eat meat because anything else can slow down their metabolism and make their stomachs more sensitive.

Bulking 101: Your cat ought to be able to gain muscle mass without putting on weight Choose whole meat proteins. Don’t go for cheat meals packed with carbs and fats.

Whatever your cat’s nutritional objectives, the food they eat should honor their natural diet and include:

  • Over 50% animal protein (as the primary source of calories)
  • %20Up%20to%2020%%20animal%20fat%20(as fats are high in energy, a small amount works well as a secondary source of calories)
  • Between 0%–3% carbs

For a malnourished cat to regain a healthy weight, a daily diet of high-protein wet food containing real meat and fish is recommended. Steer clear of products that are high in fat or carbohydrates because they contribute to unhealthy fat mass rather than building muscles and bones (excess carbs are broken down into excess fat and stored in cells).

Cautionary tips for emaciated cats

Take caution when feeding your severely malnourished cat after it hasn’t eaten in days because Refeeding Syndrome can occur. Electrolyte imbalances in undernourished cats can result in hypocalcemia and liver or renal failure when they are overfed.

When reintroducing food in such circumstances, consult your veterinarian about an appropriate electrolyte supplementation strategy (through oral or intravenous fluids). For the next ten days, when your cat is ready for food, give them tiny portions every few hours. Here’s a sample timeline:


Serving per meal(per kilo of their weight)

Day 1–3

10–15 ml/g

Day 3–10

20–40 ml/g

You can start your cat on a regular weight-gain program as soon as their vital signs return to normal and the veterinarian gives the all-clear.


How do you fatten up a cat?

Cats who don’t get enough exercise are more likely to be overweight. You can also fatten up a cat by putting wet food or canned cat food in their food bowl. The extra fat, moisture, and lower carbs make wet food a healthy method to encourage weight gain in your cat.

How can I get my cat to eat more fat?

A malnourished kitty should eat high-protein wet food with real meat and fish every day to gain healthy weight. Avoid products with high fat or carb content (excess carbs are broken down into excess fat and stored in cells) as they add to unhealthy fat mass rather than bulking up muscles and bones.

What makes cats chubby?

In addition, when cats are permitted to eat free choice (when food is left in the bowl all day), it is easy for cats to eat more calories than they need. The bottom line is that when calories taken in exceed calories expended, weight gain is inevitable, leading to obesity and overweight cats.

How can a cat become obese?

According to Dr. McDaniel, a major factor responsible for feline obesity is the practice of “free feeding,” in which a bowl of dry food is available for consumption by a cat throughout the day. Accordingly, she says: “Use canned food, which typically has a higher protein and lower carbohydrate content than kibbles.
