Our local petsmart is "good", by petsmart standards. They have 2, occasionally 3 young, healthy looking pigs in a cage about 6 square feet (too small, but bigger than most petstores give them). They have hay and veggies daily (though not in enough quantity or variety). But "good" isn't nearly good enough. They still get their pigs from mills. They still sell them to anyone who wants them, while pushing the tiny cages, dangerous "accessories" and crappy quality food. Even the local store that is partnered with a small-animal rescue still sells their own pigs from the same crappy mills. Oddly, the rescue pigs there are in small aquariums, and don't look as "marketable" as the pet store's own pigs. The whole thing definitely sends the wrong message.
Don't get me wrong-- I'm glad when there are employees who know what they are talking about in any store, but I don't know that I'd go so far as to say I was "impressed". Not by a long shot. I have to admit, though, that I question the accuracy of the original post. A manager who refused to sell a product (the animal or the cage) at a Petsmart isn't one who is long for his job.
