Until recently,I bought a lot of my pet supplies from stores that sell animals. None of them treat their animals terribly, so I didn't see the problem. Recently though my friend showed me this website: petstorecruelty.com. It turns out that all pet store animals come from places where they are kept in similar condition to puppy/kitten mills. I've now started shopping at my local holistic petstore. It's more expensive but imo it's worth not supporting this.
