An old friend of mine kept rats for years - and she could have run a circus for them. They were SO well trained - ad SO much fun to watch. With the first rat-ling (as we called them,) her mom was terrified! Whenever Mama came into the room, a whispered (had to be whispered!) "Here comes Mom-Mom" would send the little guy running from her shoulder into her pocket. That was cute enough, but then he would put his little paws on the edge of the pocket and peek his little head out until she gave him the "All Clear." He would then return to his favorite shoulder perch and life would go on. I wish we had video, but we were so young that I'm not sure we even had it! Still, I'll see that little nose twitching over paw=tips forever. What a picture!I've trained him to come when cslled and to grab his carrots with his "hands" instead of just snatching with his mouth. Yes he is very smart. Plan to teach him more soon.
