Is my aging cat's confusion and accidents a sign of dementia?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Male | neutered | 15 years and 9 months old | 16 lbs

I wanted to know if cats, or any animals, can get dementia? My cat Mister, who is almost 16, walks around my apartment aimlessly, and does it frequently. He is also vomiting and has diarrhea at times,and sometimes goes right outside of the litter box. I do have an appointment to see my vet, but wanted to get an idea of what it could be. Thank you.

Hello, yes older pets can get a form of dementia. This however is a diagnosis of exclusion and we typically recommend making sure that pets do not also suffer form things such as kidney disease, high blood pressure and high thyroid levels. Other causes such as diseases associated with the brain should also be considered. Have your veterinarian evaluate Mister and determine if bloodwork and checking blood pressure needed at that visit. Hope this helps and best of luck.
