I get a lot of questions like that. Many teachers wanting classroom pets and that sort of thing. Although I have heard of several success cases, Its just not right for most chinchillas on the whole. There is a girl on another forum who takes all of her chinchillas to work with her every day. I can't think of a single chinchilla in my herd that would be comfortable but it works for her and her herd. Maybe because she gets them at a young age, or maybe because she takes them all and there is safety in numbers. Who knows! There is always the exception to every rule. But as a breeder I would be concerned about selling one into that sort of environment.
Poor Charlie freaks whenever I take him out of the bedroom, much less a car ride to a new place, and he one of the most outgoing chins I have.
I can see why they would ask, though, (not knowing much about chinchillas). Who wouldn't hope to snuggle with one and take it everywhere you go. You know there isn't a person on the board who wouldn't carry their chinchillas in their pocket everywhere they go if the chinchillas would let us!
