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

Poor guy! It could be a sign of pain or trauma from the event including head or neck trauma, or a side effect of pain medication. If he was bleeding did they find the source of it? Was he given any medications at the clinic (pain medication?) or to take home? Was he appropriate mentally there and then has declined? The problem with kittys getting attacked is that the attacker often shakes them while biting. This can create a lot of shear trauma under the skin that is initially not seen. If no meds have been given i would worry about pain or head trauma. I would recommend calling the clinic that saw him to report this change. The safest thing for these patients is for them to be hospitalized for monitoring because not all problems show up right away. If head trauma is suspected medications may need to be given for this. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

He may be having vision problems, high blood pressure or might have had a seizure. If his pupils are wide open, please take him to an out of hours or emergency veterinarian now. He may have high blood pressure and fast intervention can reverse any blindness caused by this. If his pupils are normal and react normally, take him to a vet tomorrow for an exam.

I'm assuming you mean that your cat's eyes have been dilated for days. It could be caused by pain, head trauma, or hypertension due to kidney disease or hyperthyroidism. This is not normal, and your cat needs to see a vet immediately.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It sounds that Aurora should be seen by your local vets as soon as possible. Dilated pupils can be a sign of pain, acute blindness, high blood pressure and more. Neck flexion is a common sign of spinal pain, muscle problems, low potassium level. Please, call your vets right away and get Aurora seen today.

Hello. This odd behavior does warrant a visit yo your veterinarian, especially if it happens again. This may be nothing, perhaps a sound or something she sensed outside that caused her to freeze, but we really can not rule anything else out, including some underlying condition with her heart or even a small seizure. Just watch her & if she remains normal, just mention this episode to your veterinarian at your next scheduled visit. If it does happen again, please see your vet. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Injury caused by slamming or opening door can be serious in cats. If your Dolly does not came back to herself within 45-60 minutes after the accident, you should take her to your nearest vets today. Changing colour of the eyes, I suspect is due to dilatation of the pupils, which is a sign of pain in cats.

Trauma to the eye, head, and neck can result in many different problems. I am glad she seems improved today, but I would still highly encourage you to have her evaluated by a veterinarian. If the eye has an injury early intervention is best. Best of luck and I hope she improves soon.
