one of my cats eyes seems smaller then the other?
My 16 yr old cat is hyperthyroid...(don't know if this has anything to do with it) When she looked at me today i noticed one eye is smaller then the other...not the pupil but the eye itself...i am "assuming" it looks smaller because she either is not opening it as wide as the other one or the lid is drooping.
She is an indoor cat only. The eye is not red...running or anything like that....just smaller.
Will call the vet tomorrow but it's just really strange...any ideas?
