Wellllll now........Mine are seprated every 28 days FOR 28 days and then we all get to be together again. Chester goes to my daughters house and Giz, Amy and Midnight go to my son's. I do however realize that this has been going on ever since I got them all so my situation may be different.. But mine DO reconize and remember each other. Chester is always PO'ed when I bring him home for the first few days because he likes it better at Rie' Rie's house (lots more activity there, more hands to pet him and a dog to play with) He always has more to do with Amy, sleeping with her, following her around and watches over her.. But they DO remember one another here.
