Why is my adopted senior cat so bony and not gaining weight?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | 8 years old | 11 lbs

Hi, we adopted a cat from the local shelter. His name is Pimp Daddy Patches, he is 8 years old. He seems at first glance to be a large cat but petting him you can feel his boney prominent spine and his hips/thighs dip in. He is very lazy often sleeping in the closet under the shoe rack and only comes out a couple times a day. He is eating and drinking, no sudden hair loss, he isn't really lethargic or anything. I'm just concerned about him not beefing up?

Thanks for using Petco Pet Education Center, formerly Petcoach! It is difficult to tell based on these pictures if he has a thin body condition. Weight loss or lack of weight gain can be seen with gastrointestinal disease, renal or liver disease, among many others. I would recommend that you consider having him evaluated by a veterinarian for further assessment. Further diagnostics would include general labwork and possibly an abdominal ultrasound and a GI panel. Treatment if any would be based on findings. Good luck and have a great day! I hope you find this information helpful.
