My old cat is losing weight, eating, but not gaining. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 21 years and 4 months old | 4 lbs

My cat used to weigh 18 lbs and a couple of years ago she started to lose weight. She now weighs 4lbs. And her gums have over taken her teeth so I have started feeding her wet food which she eats but she is not gaining the weight. I am really concerned, but have not been able to take her to the vet due to us having to move unexpectedly and a disabled parent to take care of full time. Please help.

I am so sorry to hear tat your pet Skye is in such poor medical condition. That is a lot of weight to lose and I am deeply concerned that her heart may not be able to take that level of weight loss much longer. She needs medical attention ASAP, because this could be something that is treatable, like hyperthyroidism. Other possibilities are intestinal parasites and cancer has to be considered due to your pets age and gradual weight loss. I also am not sure how your pets appetite is or if she is having loose stool, causing her to not absorb the nutrients she needs. More information is needed here to make any more recommendations on how to proceed with your pet Sky's care. Perhaps a consultation will allow you to voice all your concerns and receive adequate advise for her.
