I think some pet stores are okay. I was actually surprised when I saw that petsmart was selling chinchillas. Mainly because in my opinion, they need a little extra care then the animals they normally sell. When I first saw the chin, I said 2 things. I feel sorry for this animal and I would never buy it.
When I got my first chin, I did buy it at a petstore. The owner said the chin was very tame. Well they were wrong. I paid around $150 for the entire set up which included the bedding, cage, water bottle and all that jazz. Well I was disappointed when it was only like a small cage that was only big enough for a rat. And unfortunatley I couldn't afford to buy the big leveled cage. I did try to set it up good for my chinchilla so she would atleast have some things to climb on and be happy. The chinchilla could never be tamed. If you could catch her, she hated to be held, and could usually wiggle her way out of your hands. About 2 months after that I was in another petstore and I found that they had another cage set up (this was a really crappy pet store, they have TONS of animals and no space, and it stinks like I don't know what) but I decided to buy it because the cage was huge, and had everything included and the chinchilla was male, so I wanted to mate him with my other chinchilla. Again, this chinchilla couldn't be tamed. Eventually my chinny had a baby and of course, he didn't have any choice but to be tamed...lol...
Me and my boyfriend broke up and I lost my chinchillas (he sold them both for $100 including the cages and everything) but I like the memories I have with them. I did hear that she had 2 more babies after I told the woman she had to seperate them, and of course she wouldn't let me buy one
I guess my point is, when you're buying from most pet stores, you don't know what you're getting. In my opinion some of the chain stores like petsmart are okay to sell the smaller rodents, but not exotics. And also, I wouldn't buy anything from superpets , my boyfriend was looking for birds and they didn't even know how to stand on your hand...it was sad.
