cat going blind?

[queribus]

How can i tell if my massive part-Bengal cat is having eye sight problems? He is very quick to 'attack' especially if someone tries to stroke him, and his pupils don't dilate even in bright light.

He'll also eat anything, steals food and bullies his sister.

Had blood tests done which didn't show anything abnormal, e.g. liver, kidney, diabetes etc.

any thoughts?

Pupils contract in bright light. The vet checked his eyes?

How old is he? And what makes you suspect he's got eyesight problems. (Other than the attacking people - and Fluffy would be better placed than I to discuss that with regard to Bengals as she has one.) Is he bumping into things or making silly mistakes?

IME bumping into things and sitting in unusual places is a sure sign that your cat's eyesight is not what it used to be. Is your cat doing this?

Is someone trying to stroke him from a different angle or are they approaching him from the front where he should be able to see them?

I think if you are in any doubt, take him back to the vet for a check-up.
