The problem: He’s a biter. He used to spend half his time sleeping, ¼ whining and ¼ playing. Now he whines much less and plays more. He plays with anything on the floor and just as often, his lower half with seemingly no control over his legs (kicking himself and crying from him biting his own tail). When I pick him up he instantly starts purring. (When he was littler he purred so hard that when I saw him I thought there was something wrong.) But other times he plays with my hands and feet and randomly just rares back and takes a chomp at me with no warning.
I’ve tried blowing at his face and now he’s actually started reacting to a Neeeh! noise but I’m trying to find a solution for his biting because we’d like to adopt him even with the biting. (I don’t want someone not prepared to adopt him.) But I need to know why he might be doing this (he shows no signs of pain) and how to correct it.
