My cat is very skinny, always hungry, and losing weight. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | 7 lbs

We got our cat from the pound about a year ago. They estimated his age to be 2 years old; however, we believe this was not accurate since they had most of the cats listed as 2 years old. He weighed about 14 pounds when we got him. Over the past six or seven months, he has dropped about half of his body weight and is very skinny. He seems to be in fine spirits, but seems hungry all the time. I have given him tapeworm medication twice, but that did not seem to help him gain any weight. Thoughts?

Significant weight loss is always a concern, especially if his appetite is good. Hormonal conditions such as diabetes and thyroid disease or poor absorption and digestion of his food is possible and I would recommend a full physical and blood panel as soon as possible in order to stabilise his condition before he becomes too frail
