senile cats

from this discovery article:

Mental disorders associated with aging, including Alzheimer's, are far more common in domesticated cats than previously realized, with more than half of all cats over age 15 showing signs of senility, according to a forthcoming Journal of Small Animal Practice paper.

The findings support a growing body of evidence suggesting that most, if not all, mammals, can suffer age-related conditions normally associated with people.
