But please, don't go out and buy them all-- that only fuels the industry.
How long would you expect animals to stay in a pet store before being bought? A few days? A week, maybe? Animals can actually stay there for much longer. I know a parrot at a pet store who has been around for weeks and weeks! One can only imagine the boredom that they find there, with no playmates to play with, no wide-open spaces to fly over, and no excursions to go on. It must be awfully boring, even depressing!
Helping the animals at a pet store can be tricky. After all, we can not buy them, as this supports the cruel breeding industry. However, there are a few ways to help them endure the boredom of glass cages.
3. Ask the pet-store if you could be a volunteer to take the puppies out on walks or socialize with them. Let them expend some energy, have fun, and get used to humans. This doesn't help the business at all, but it does help the animals!
4. Write a letter to the pet-store chain director and say that you are concerned for the well-being of the animals being sold. For example, you could ask them to start selling animals from shelters instead. Tell them that you won't be buying any of their pet products (eg. hamster wheels and pet food) until they start bringing more ethically-sourced animals to their store. Be polite, but assertive.
5. Support shelters by buying supplies from them, if they sell any. Or at least buy supplies from a store that sells animals from shelters. None of them in my city are perfect, I know, but it is good to support the most humane ones.
There really are so many ways to help animals, when you think about it. So much can be done!
