breed

Q. I am disabled, and am on extremely limited income. My cat who is 10 now just today exhibited one pupil being larger than the other.

A. Has your cat ever had a blood test? is he drinking and urinating a lot? if he is he might have kidney failure which can cause high blood pressure and lead to eye damage and blindness.

This could also be caused by a trauma, if he goes outside he might have been hit by a car.
