Hi there, i resently had to take my cat to an emergency vet clinic after he had a bad cat attack and couldn't walk and was in a lot of pain. they had to sedate him in order to check him over so i left him with them for a few hours. The following day i noticed that he actually couldn't see anything at home and had issues with going outside or using the litter tray. We took him to our normal vets where they adminstered a pain killer which then made him go to the loo - i think he had been building it up. They said the blindness was not due to high blood pressure so it must have been the sedation (as they did mention it took a while for him to go under). Just wondered if anyone else has had a similar occurance, hes only 10 and i'm really hoping its not going to be a permenant thing. Any ideas welcome as we are soooo frustrated this has happened!!! Thanks
