Hello and welcome...Sounds like your poor kitty may of been hit by a car. He clearly has a head injury at the very least. Please get him to your vet ASAP.
Let us know how it goes, okay?
I agree with Jade, symptoms like you describe indicate neurological damage.....the Vet can give him a med to take some of the swelling off the brain, than hopefully he can regain his sight and balance.
Sending my prayers
This definitely sounds like your kitty has a head injury from being hit by a car. I'm also very concerned that he has a jaw injury that may prevent him from eating.
Your cat needs to be seen by a vet asap!!
Agree with all, this is hardly a forum issue, he needs to be at the vet 'yesterday'.
Agree with all my fellow posters---I am hoping you have already seen the vet???
Could you please give us an update?
