We've never crated.. Matilda was a 18mos when she came to live with us, and only pottied in the house the first day - thats when she got overly excited we even let her in the house (she was totally outdoors with the previous "owner") Since then, she's never had an accident nor has ever been destructive. DH and I work different schedules, so for the most part she's alone in the house for MAYBE three hours at the most, in which she has free reign. I make sure and regularly rotate her toys though, just in case.
