Also wanted to add... Know someone whose daughter did a ton of research and adopted a skunk from a good breeder. After about 6 months she had to find a new home for it. The mom told me that it was like a ferret, only bigger (in behavior and smell) very smart, but that it was also quite destructive. Like others said, needs to be confined when you're not around and not given access to things you don't want scratched / chewed. She also said that it was nocturnal.. No one had emphasized this to her daughter and it ended up being a big deal for them.
This is exactly why we inform our customers who show the slightest interest in getting a skunk!
missriss- That's great that you inform your customers well. I'm not sure if the "breeder" that she got it from didn't do a good enough job of warning her or if she just couldn't "handle" what she thought she could.
It sounds like they can make great pets, but are pretty high maintenance.
