So, if you notice your furry friend is losing too much weight, you should immediately seek help from a veterinarian. Your vet will be able to determine what is the cause of unhealthy weight loss.

Buying Guide – What To Look For In The Right Canned Cat Food For Weight Gain

Helping your underweight furry friend gain weight is more about feeding her the right food. However, the best food isn’t just calorie-dense but should be able to offer balanced and complete nutrition.

So, to ensure you’re giving your cat the right food for weight gain, there are a couple of things to consider. These include: 

Protein Content

Protein is the most important part of a cat’s diet whether he is overweight or underweight. But if your furry friend is losing weight, you should choose a food that contains high-quality sources of animal protein.

You can opt for canned foods that contain real meat from chicken, salmon, tuna, or poultry as the first ingredients. However, make sure the diet has at least 26% crude protein for adult cats and at least 30% for kittens.

Foods with high contents of protein help your feline maintain healthy lean muscles and weight.

Wholesome & Natural Ingredients

Also, worth considering is the quality of ingredients the canned food is made with. Generally, the more natural your feline’s food is, the easier it will be for her to digest it.

Therefore, we recommend you choose foods that contain only wholesome and natural ingredients. The ingredients should also be carefully sourced to ensure their quality and safety.

Additionally, make sure to stay away from foods that contain any by-products, artificial additives, fillers, and artificial preservatives. Such formulas don’t offer a valuable source of nutrients.

Age of your Cat

Different foods are formulated to meet the unique needs of different cats. Some formulas are made specifically for kittens while others for senior felines.

On the other hand, some foods are designed for cats of all life stages. So, before choosing any food, it’s important you determine if the food is appropriate for your cat’s age.

You don’t want to give your adult furry friend food that is meant for kittens. This is because it will probably not meet your cat’s nutritional needs. As such, your cat may continue losing weight.

Higher Content Fat

Fat is known to be very rich in calories. So, giving your underweight feline a higher fat content diet could help her gain weight.

Some of the best canned foods contain 22% to 28% fat, mostly from animal-based sources like fish oil and chicken fat.

Flavor, texture, & Smell

Let’s be honest, cats are known to be finicky eaters. One cat might find foods with a chicken flavor irresistible, while another will not dare eat it. On the other hand, some felines love their food dry and others wet.

So, we recommend trying the different recipes we’ve recommended above until you find one that your cat loves.

Frequently Asked Questions

In this section, we look at some of the frequently asked questions about the best canned food for underweight cats.

Q: What can I feed my cat to help her add weight?

A: Any food that contains high protein content and fortified with minerals, vitamins, L-carnitine, and powerful antioxidants can help.

Q: Why is my furry friend so skinny yet he eats all the time?
