Best high-fat, high-protein food for an underweight senior cat?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 16 years and 11 months old | 3 lbs

Hi We have an older cat who has a skin tumor on top of here head. Although fairly large it does not seem to cause her pain, and she has decent quality of life. She has seen a V O and there is not a lot of treatment options for her. One side issue is rather severe weight loss, and while she is stable in that now, At only bout 3 pounds she's far too thin. Could you recommend a high fat / medium high protein food--dry or wet---we are lucky that most of the time she has a good appetite Ken

I am so sorry to hear that Snuffy has been diagnosed with a skin tumour. Thankfully it sounds as bough you are ensuring she has a great quality of life. This would be my best food suggestion to help her gain some weight; I would suggest adding boiled skinless chicken breast to Snuffy’s diet to help her get extra calories and protein. This will help her gain lean muscle mass. There is also the possibility that Snuffy could have a metabolic or kidney concern in addition to the skin cancer. These could be causing her to lose weight. If you haven’t recently I would suggest a blood test to rule out these diseases at your vet. Thank you for using Petco Pet Education Center, formerly Petcoach and pleas eknow we are here to suport you and Snuffy.
