Why is my senior cat losing weight, lethargic, and walking slowly?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 11 years and 3 months old | 7 lbs

My 11 year old cat has lost a lot of weight, he has a decreased appetite and he seems lethargic. Also, he walks very slowly and low to the ground. What can be the cause of this?

Hello, thank you for your question about Bramley.

Inappetance, weight loss, and lethargy are nonspecific signs that can be indicative of many different underlying diseases. It could be a sign of a problem within the GI tract such as inflammatory bowel disease or other disease conditions. These symptoms can also be signs of a systemic condition such as liver or kidney disease, pancreatitis, or diabetes. Based on the low walking/weakness you describe I would want to perform diabetic screening.

I would recommend having Bramley seen by your veterinarian so that they can examine him and discuss performing additional diagnostics such as systemic bloodwork. Depending on the results of this bloodwork they may also recommend performing an abdominal ultrasound.

Hope this helps, good luck!
