One of my 8 year old cats, Jamie, went to the vet for bloody urine. He was given Baytril and sent home 20 hrs later. Upon arrival home, I put Jamie in the bathroom where his litter box is, incase he was still dripping blood from his penis. My other cat, Jesse, is his buddy (we got them at the same time and he is also 8 years old) was with him. Jamie attacked Jesse, so I separated them. About 10 hours later, I tried to let them together again, and Jamie viciously attacked Jesse. I have separated them again but need to know what to do. I love both these cats so much and I am so upset by this. They have NEVER fought like this before. Any suggestions???? Sharon Chapman
