I know this is terrible to say, but it is probably a bad idea to buy the animals off the store. I've been in the exact same situation and felt incredibly compelled to buy the animals and give them some chance at life. However, I'm scared that by doing that I would be reinforcing the system and making space so they can hurt even more animals. I say if you really really want to buy the animals, then go ahead and do it. The best solution is to call animal control and get some action against these people happening. I'm glad there are people in this world who actually do care about what happens to these poor creatures.
