Most of us would consider owning a pet snake as an odd choice, but it’s much more common in America than you might think. According to the US Pet Ownership and Demographics Sourcebook, around 550,000 American households owned one or more pet snakes in 2011. That’s about 1.15 million of them!

An octopus is an even weirder pet, although there aren’t any official stats on how common they are. Even so, the cost of these aquatic animals can be pretty high, ranging from $20 to $1000. And that’s just for the animal – a tank big enough for an octopus is, on average, around $300.
