Why is my 15-year-old cat losing fur and drinking so much water?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 14 years and 9 months old | 6 lbs

My cat is 15 and seems to be losing small patches of hair. The skin underneath is white but there's clumps of hair everywhere. She is also drinking a lot of water. Does anyone know what this might be?

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. I think it may be that Morgan has diabetes. Drinking an excess of water in a cat is almost always diabetes especially with the concurrent hair/skin signs you are seeing. Usually that is due to a failure to groom themselves as they normally would. Of course, some other common differentials would be kidney disease and thryoid disease. I suggest you get Morgan to your vet for an exam and some blood testing. Those diseases are easily diagnosed with some simple blood testing. Hope this helps. Best wishes to you and Morgan!
