How are ferrets and wolverines related?

No. Ferrets are not related at all to rats. Rats are rodents, ferrets are related to skunks, polecats, otters, and weasels. Ferrets are more like the responsibility of a cat or dog, as they are very very social and need attention at all times. Please if you are getting a ferret, DO NOT put wood shavings or newspaper as their bedding. They need soft blankets, hammocks, and even old t-shirts would work. The shavings cause problems with their lungs, and is really bad for them!!
