My old cat is too thin and won't eat. What supplemental food works?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Female | spayed | 5 lbs

My elderly cat has always been thin, now she is extremely thin. I recently switched her to kitten food, both wet and dry to boost her caloric intake. She eats very little and my question is about any supplemental food I can add to boost her weight. Thank you

Have you had Skittle checked out by a vet for this weight loss? It could be due to something serious like kidney failure, liver disease, diabetes, hyperthyroidism, or even cancer. She needs to see a vet asap for this weight loss, and I would recommend getting a geriatric blood panel and urinalysis. Please take her into her vet in the morning. I would not give any supplementary food until after she sees her vet. Best of luck.
