I had all kinds of rodents growing up, pretty much everything you can get from a pet store (mice, rats, hamsters, guinea pigs, gerbils), so when chinchillas started being sold in the pet stores we bought our first one since it was something new we never had before, and unlike other rodents they can live a long life. Unfortunately we didn't really know much about them, other then they were a rodent that have very soft fur and were bred for the fur industry, and they required a different diet then the other rodents I had. We did try to research on them though, and did our best with the limited information at the time, this was in the early '90s so when the internet was just becoming a thing (I don't think we even had the internet when I first got them), so at first it was mostly info from the pet stores, books, and talking to the couple breeders we knew in person.
