I adopted a rescue Maine Coon male one year old this past August. His name is Max. I dearly love my big boy, but he has a serious problem. He is very aggressive. I need help. I am at the end of my rope. My vet has put him on medicine but so far it's not helping. He attacks me with out any advance warning. He has bitten me so many times. I have scars on my hands, arms and legs. I have tried water bottle spraying, time out, medicine and calm voice. So far nothing has worked. He is getting worse. I can't put him up for adoption. He would seriously injure a child. Any advice would be much appreciated.
