we bought several hamsters from petcetra and have always had healthy animals. Recently we bought what we thought was a boy hamster he was kinda cranky but we discovered he was a she and they took back the mom and babies and allowed us to get a new one for my son. Also we buy all our pet food there and they keep the special foods in stick just for our needs. staff are well educated and do enjoy being with the animals. Thus far they have interacted with both my kids and animals with a real sense of ease.
