Wow, Hannah, Serously? I've never heard of ferrets being illegal!!! And yes, they have a tendency to bite, but you can train them not to with enough thumps on the nose when they do it. They are very intelligent, so they learn quickly... Pretty much their only flaw is that they like to hide things, or steal things, a LOT... keys, shoes, socks, and they also like to get into things like potted plants. But, they are such hilarious creatures.
