10 High Calorie Cat Food Options To Help With Weight Gain

Sandy Robins

By Sandy Robins


There are many reasons a cat or kitten could be severely under-nourished and need a high-calorie cat food to help gain weight and boost general feline health and wellbeing. Fortunately, there’s a great selection of both wet and dry recipes, all readily available off the shelf, that can be a nutritious fix.

A high-calorie cat food offers cats a well-balanced diet that features protein – meat, fish or poultry -- as first ingredient and contains no artificial flavors, colors or preservatives. 
Because cats often have preferences when it comes to taste and textures, under such special circumstances, it’s a good idea to cater to a feline’s favorites, particularly, if the cat needs encouragement to eat or is a fussy eater.

Measuring dry cat food calories

Dry food recipes show the calorie content of a cup of food in Kcals. For example, a recipe that has 497 kcal/cup ME (metabolizable energy) means that one cup = 8 oz of that food = 497 calories. 

Measuring wet cat food calories

Cans and pouches show the kcal content in terms of the weight of the food, for example 96 kcal/3oz can or 177 kcal/5.5oz can. 

When to feed a high calorie cat food:

  • When a cat or kitten that has just been rescued and is severely malnourished.
  • For a frail or elderly feline.
  • For a sick cat that has lost weight as a result and now needs to regain weight.
  • Post-surgery to boost a quicker recovery. 
  • For very picky eaters who are not getting enough proper nourishment.
  • For a cat that may have run away in a storm, been trapped in a natural disaster or, displaced over a holiday period, and not eaten for a several days.
  • When a cat is suffering from stress and anxiety as a result of a change of circumstances in a household.
  • For cats with dental issues (once they have had veterinary help to resolve the issue and quell any pain).

How to feed an under-nourished cat

Selecting a high-quality natural food rich in meat proteins is a great way of helping finicky eaters find a food they will love and eat. A texture your cat most enjoys will matter too, confirms WellPet veterinarian Danielle Bernal DVM.

“A frail or ill cat may prefer to eat multiple smaller meals rather than being fed one big meal."

But given that cats generally are nibblers and prefer to eat on demand, Bernal suggests that the main focus is ensuring that the cat gets the required number of calories needed in a diet to meet its nutrient requirements.

Young kittens generally require more meals in a day. However, if you are trying to boost the health of a severely under-nourished kitten, Bernal advises more frequent feeding. 

“A very young kitten will need to eat more frequently than just key meals,” confirms Bernal. “I usually suggest just ad-libbing it until eight weeks of age, dividing out their calorie requirements. Then four meals a day until 12 weeks of age before moving to an easier routine of twice daily. Given cats tend to eat multiple meals throughout a day however, and if you feed a wet and dry combo, I suggest leaving the allocated dry food amount out all the time so that a kitten can eat on its own schedule.”

If you are feeding a cat a high-calorie cat food because of a special situation, it’s a good idea to have a discussion with your pet’s veterinarian or call the Wellness consumer hotline for advice regarding feeding the correct amounts to meet such specific needs.
