Awww, that's so cute! One of my Moluccans I had trained to go to the bathroom when I told him to (actually, I just knew when he had to go and I'd take him off my shoulder, hold him over some bushes or somewhere appropriate, and say "go potty"..and he'd lift his tail and go. It was so funny how people would stop if they saw me doing it and just watch in amazement, but Valentino didn't really like strangers WATCHING him go to the bathroom, so sometimes he'd put his tail back down and wait til they left, LOL. And people would say "HOW do you make him do that?"
. Uh....they just go, LOL.
Too bad I didn't have him very long after I got Max....that would have been funny to have him help train him, hehe.
