This really is the first technique that Potato used to steal the tummy treat from Fuzzy. He came up and bumped him on the back, then ran away fast. When Fuzzy turned around to see what happened, he circled in from the other direction to nab the pellet. I had to help Fuzzy free it from him. Pretty smart for a guinea pig.
Of course, Fuzzy's no dummy. He fell for that once, but never again.
