Answered By

A. This phenomenon is called Anisocoria (inequality of pupil size). There are several different causes of this including glaucoma, anterior uveitis, cancer of the eye, old age change, etc.
To help pinpoint what could be causing your pets condition I would recommend a thorough eye exam. Your vet may need to refer your pet out to an opthalmologist if any abnormalities are seen that need further treatment.

A. This is called anisocoria and usually a sign of a neurological problem. You need to take your kitty to your veterinarian for an exam.
