The health benefits of pet ownership are well-documented -- lower blood pressure and less stress among them. But not everyone is able to keep a pet. Allergies, lifestyle, and restrictions on pet ownership in living spaces can prevent animal lovers from having a pet of their own.

In Tokyo, it's especially hard to keep a pet. The market for apartments is competitive, and landlords are increasingly banning pets from their properties. But a new cafe allows people to reap the benefits that pets can offer, without all the hassles that pet ownership can bring. At the Calico Cafe, customers can drink coffee, order snacks, and shop for a variety of goodies, all while enjoying a cuddle and a purr from the stores many cats.

Would a similar business be popular in the U.S? What do you think?
