We don't have any pets (DH is allergic), but we took the kiddos to Petco today just to look around. They loved seeing the fish, hamsters and birds. The store didn't have any dogs or cats today though, I think they only have them on certain days when they bring them in for adoption from the humane society. So that was a little disappointing. Also, the employees were a little less than friendly, not rude but not really interested in us. Maybe they could tell we were just there to look. But it was still a fun place to go. Maybe someday we'll get some fish.
