My cats know their names and they know who's who. I think that's pretty good after only 3 weeks with me. This morning I woke up alone in bed (an unusal occurance in & of it self) Then I called Levi & he came running. Usually they both come when I call one name. So after I said good morning to Levi, I called "Where's my Jordan?" & then Jordan came running. It was so cool. I think they learned there names fast. They're my smart little boys.
