My cat's eyes are dilated and he's acting strange after being outside.

Pet's info: Cat | Domestic Shorthair | Male | neutered | 13 years and 11 months old

My 14yo cats eyes are dilated in bright light and he has a tender spot near his nose. He was outside for about 2hrs today (normal) and when i came home he was behaving strange. He was cowering and hid under the bed. He came out for dinner and treats & he's been to the loo. I'm suspect he's been in a fight or had a knock to the head. I've done a nose-to-tail check and all else seems fine. What other signs should i look for and should i take him to the vet? Your advice is appreciated. Julie

I would recommend a vet visit. If he was outdoors it's impossible to know what trauma may have occurred, or in an older cat hypertension or cardiovascular event is a potential worry with dilated eyes. To be safe I would recommend getting him to the vet today. In the case of head trauma or even hypertension the sooner treatment is instituted the better the long-term outcome. I hope HeyZeus is back to normal soon. Thank you for using Petco Pet Education Center, formerly Petcoach
