My Binx is 5 months old and does not like other people. He is very much playful, but has a real biting and scratching problem. It is not as bad with my mom, sister and I, but when he knows my dad or any other human male is around he runs and hides. Today I handed Binx to my dad so he could pet him when he attacked my dads face and hissed. I don’t know why he did it but he only does it to men. Please help me understand why so that I don’t have to put him away anytime a guy is around.
