Mario is not potty trained, but I have heard they can be if you get them young enough.
The one I had that died, she would wear a diaper when I carried her to the schools visiting. Put her in a pink dress. I always made sure I carried some raisins, potatoe chips with me, so the children could feed her. She was the tamest of the two.
I don't really trust Mario enough around a crowd of children. Otherwise, he does just fine with children unless they threaten him in some way. Then he will start making a screaming sound.
He does like to eat anything that we will, he has his dislike and of course his favorites. He has his own house outside that is heated. The little rounder does get in the house every now and then, when he does he steals everything he can get his hands on. Food out of the cabinets, my husband's cookies. They can make an awful mess. Redecorate your house if they want to.
Maio is very sweet and loves to be tickled, and loves to wrestle. Don't get me wrong, I have been bitten plenty of times by him and his late mate. I do have a way with words..
