I had 3 cats together, A RTC , TSN and a marble cat. They all get along fine except my RTC is trying to eat the marble. No aggression just open jaw feeding attempts. I decided to spare the marble so in I went to get him and my TSN went absolutely ballistic He hit every wall about ten times and made a mess of everything The RTC just moved out of the way slowly, the marble didnt have a clue and swam into the net but that TSN !!!!!!! What a crazy SOB. Its amazing he didnt kill himself.
