Teeth cleaning

Hello,
I have an eight year old neutered cat who has been very healthy his whole life. He goes for regular check ups and shots. He has always been very chatty and social. His last checkup indicated that his rear molars needed some cleaning. It went very well said the vet. He had an IV. That happened on Tuesday. It is now Saturday and one of his pupils has been consistently larger than the other. There doesn't seem to be any behavioural changes, nor is there any swelling or pain in the area. I have seen His back end slip out from under him a few times, though I'm not sure if that is because of new hardwood floors. Any thoughts?

Aw, what a handsome guy! I would contact your vet and tell them what you are observing. Are you noticing anything else? Is he eating and drinking normally?

Signs of a stroke in cats can include any of the following: oddly dilated pupils (one larger than the other), rapid movement of eyes, tilted head, walking around in circles, and/or loss of control of back legs.
 

No matter what different drugs my present vet uses on my cat and also halving the dosage since he's 16 years old, after being sedated for any kind of medical procedure, his eyes always stay dilated for 48 hours until the drug completely leaves his body.

Since my cat's eyes have always done this, both my past retired vet and his present vet thinks it has something to do with his genetics.

Thank you, both of you. I will give them a call on Monday. His appetite is great and he isn't confused or walking in circles... I did a little test with a light and the left one (the one that is the smallest) reacts very quickly and shrinks to a pinhole. The right one (the bigger one) doesn't contract very fast and stays quite big. This was his first time under anesthetic so I am really hoping its just genetics...

Look who has normal eyes again! He is not squinting anymore either! I am hoping its just the genetics thing (6 days is a long time though). I will still call the vet tomorrow (today is a stat day) and let them know.... Thank you so much again for the info! He is a very handsome, smart and social boy and I would be devastated if I lost him. I don't know if I would do the cleaning again, as they weren't that bad, it was more just preventative.

I'm so relieved! And you're welcome! I love his little orange mustache. 

Yeh, anytime a cat gets put under anesthesia, it can have adverse effects. I just had two of my senior cats put under for dental cleanings and extractions, and I won't put them through it again. I just have to keep up with it by brushing their teeth.
