Ah, here’s the stuff about foxes: http://en.wikipedia.org/wiki/Domesticated_silver_fox
My main point was that it’s probably easier to start domestication with animals which can get not only get tamed (like elefants), but are even in the wild accustomed to live and interact with humans. Though, as I just remembered, that applies to foxes, too: Plenty of those live in metropolitan environments and quite a few have let themselves getting tamed.
Still, I think racoons would be an obvious example as candidates for domestication, if we set our minds to it. But why would we want something even more mischievous than cats in our homes. At least cats don’t come with thumbs.
