First Aid and Emergency Care

My ct came home the a week ago now he had a bad cut on his foot. I took him to the vet. They cleaned him up gave him mes for pain and antibiotics. Now he isn't ating well t all can't chew hard food. I have ben cooking him chicken. But his jaw is chattering and he is druelling terrible. They sid he had a bad smell in his mouth but I did not have enough money to have any more tests done. Could you tell me what this may be.
