On average, we found that dog owners spend more than cat owners, but owners of small mammals (like guinea pigs, hamsters, and gerbils) spend more than dog and cat owners combined! Fish and rabbits make the cheapest pets, followed closely by mice and rats.

What’s in the “other” category that’s costing so much? Your guess is as good as ours. Alligators? Wolves? Zebras? Dinosaurs? Whatever exotic animals these people are keeping sure cost a pretty penny to own!
