My adult male cat (8 years) has been vomiting and shaking his head (holding his ears down and scratching at them) since Thursday afternoon. I did take him to the vet Friday morning but they didn't know what was wrong. The vet gave him 2 shots, Penicillin and a combo of Tagament/Reglan to calm his stomach. He didn't vomit Saturday but started again today. He is not keeping any food down. He seems to run around the house fast and sometimes seems to bump into things. I'm worried about him. The only new thing in the house is I recently (last Tuesday) started using some lysol to clean up my cat's mess. He does go outside and so I wonder if maybe he got into something since it started shortly after I let him in that day. He did just get a rabies shot about 2 weeks ago. I declined the distemper and leukemia. Doing a quick search online it makes me wonder if he does have distemper. He could have picked it up at the vet since the virus supposedly lives on surfaces a long time despite cleaning.
