Well, kitty Mohammed Ali turns 3 years old on 4/20 +snicker+ With my brothers both working/going to school and I, on the road more now than I ever have, is it time to get him a friend? My concerns: He's a very strong and aggressive feline and has chased all other stray mammals away from our balcony. My flat is definitely large enough, but the little guy's a bit of bully. He attacks dogs, when we get mail and go to the stores below us. He has even attacked several humans who have visited. He is very loving to us three boys(men)though. I know, I will talk to a professional but I'm work and thought I'd run it by you guys. Any of you introduced a second cat, years in?
