Omg! Freddy sometimes nibbles at the hairs on Joe's arm. Sometimes he gets rough and Joe puts him on his cage top when that happens. So I guess no interactions is the best way to handle that?I still have my original thinking. Bob, feel free to comment. I think it was a combination of things. Starting with Elvis wanting attention and Howie not paying attention. Then hormones hit. And the nibbles became bites because Howie reacted to them. So in Elvis's mind the bites were working- he had Howie's attention. Then it became a game to Elvis. And then I think as Howie got more frustrated with Elvis, Elvis sensed that and got frustrated with Howie. My guess at least. Undoing it all is the problem. And sadly, Howie just doesn't trust Elvis anymore.
