Pretty small selection of supplies, large selection of animals.
I don't know about other animals, but I definitely wouldn't recommend buying rats here. They don't separate their males and females, so if you buy a girl rattie make sure you have space for a surprise 9-for-the-price-of-one deal on rats.
The knowledge of the staff is very sub-par. They believe the myth that handling baby rats will cause the mother to reject them. This is not true! In fact, not handling baby rats from day 1 results in skittish ratties that are terrified of people, which the rats from Pet Kingdom certainly are.
It's not the worst thing, but it makes the rats much more difficult to train and bond with. Better to find a reputable breeder who knows how to raise properly socialized, cuddly rats.
