So a 2 weeks ago my cat became registered for diabetes. We gave him shots to control it. The shots must have been to powerful because one day I found him lying on the floor twitching. I brought him to the hopsital and they said he had a siezure. I know these can be damaging to the brain. I brought him back today and he kept doing a strange thing with his mouth were he would flick forward and back his tounge. He also seems to be avoiding us. So do you think that he has become mentally disabled? I know it's king of random I just want to know.
