They also adopt our their "non-adoptables" to various rescue groups instead of disposing of them or euthanizing them.
The one I used to work at did that as well. I remember one time someone returned a hamster that was missing one eye, they said it was like that when they brought it home. But we know that we didn't sell it like that. We glady took it back, and kept him in his own space and played with him everyday. Then we ended up giving him to one of our regualr customers who worked with special needs children. The kids loved him because he was a special needs hamster just like they were special needs kids.

I agree with Aly that the prices are a little more expensive which is why I rarely shop there, but I do think that in the end it balances out since you get every 10th bag of food for free.
