Other potential reasons why senior cats have less appetite and lose weight include tooth and gum problems, hyperthyroidism, kidney disease, feline leukemia, and other health issues.

To get your old cat to eat more and gain weight, start by giving a high-calorie, nutrient-dense cat food. Avoid overloading your cat with carbohydrates because their digestive system is not designed to digest and metabolize carbs efficiently.

You may also enhance the palatability of the food by offering stronger-smelling foods, or with the help of food toppers. Heating canned pet food for a few seconds on the microwave can also help release the flavors and odor. Remember to transfer the content onto a microwave-safe bowl!

You may also ask your vet for appetite stimulants.
