Wow, what an interesting thread. I have never seen a suger glider at a pet store before, but if I did, I would probably ask alot of questions from the people who work thier about them before I buy one. I would think most people would.
Also, my fiance bought one of our ferrets on impulse, and I think we did great with him and learned way more about ferrets by having one then you could probably ever learn in a book. Now we have 3, one of them is adopted. I do agree that there are pet stores that don't know thier stuff, but the only way to get rid of stores like that is to quit shopping there.
For example, Petco sales ferrets, and allthough they are really good about keeping thier cages clean and the ferrets healthy, they don't deal with them enough and they tend to be really nippy. As for our ferrets, we got at a local pet shop, and although they were not good about keeping thier cages clean and the ferrets clean, they did provide a lot of love and attention and were knowledgeable about thier pets. Buddy came home with fleas but was the friendliest ferret in the world. So what do you do in situations like that? I plan on adopting more then going to pet stores. I don't think we could ever put an end on pets being sold at petstores, it just happens to be a convenient place for people to get thier pets rather then trying to find a breeder (who can also be just as bad as pet shops) or a local shelter (which you have to go through the hassle of being an aproved pet owner)
Just look at it this way, although it is horrible and cruel when and impulse pet owner gets rid of thier new pet, that just gives them a reason to appriceate thier new perminant owner more! Thier is evil in this world, and although we would like to get rid of this evil, without this evil we couldn't define what is good. If that makes sence to you all...
