My 3 year old corn( that iv had for 2 months) was acting weird tonight. He kept opening and closing his anal flap(i believe that's what its called) as if he was going to poop. He does poop on me often if i hold him and he has it. Hes pooped 2 times and should have nothing left. My fiancee suggested that he possibly does it when ever i hold him like a defense mechanism but i just havn't noticed. Any ideas?
