One petstore I went to (forgot the name) had big cages for there pigs. They were about 2x3 feet and there was only 2 in there but they were aqariums. The store also lets you go in and you can just pick up the small animals right out of there cages. They also sold dogs and they were kept on wire in small cages too-the dog were in cages about the same size as the pigs cage. Unless they were big dogs then they had a bit bigger cage.
I don't think all pet stores suck, just the ones that sell live pets do (because if you didn't have pet supplies how on earth would you spoil them? lol.)
Ok, let's stop discussing which is the worst. They are all chains with many stores, so it just depends on the local management. Some may be better in certain areas while some are not. They (almost) all suck. Gr...
