We have several PetSuppliesPlus stores within driving distance of me. I find them to be a decent store for the most part. Some of their stuff is overpriced, and their employees try to talk people into buying all kinds of wierd cheapo/strange foods, but overall I think they're an ok store.

I confess I've never paid much attention to the fish/birds in the stores, however their guinea pigs (which I have to go look at everytime I go in since I owned GP's for 10 years) seem to be well cared for in most of the stores, there is one store that does an awful job with them, but it's the exception not the rule of the stores I've been in.
