I suppose anyone not living in Tokyo probably can’t understand the rise in popularity of cat cafes in Tokyo and “rent a pet” services. This article describes the author’s experience of visiting a “cat cafe”.
Most people in Tokyo live in tiny apartments which are often barely big enough for one person, let alone pets. Many apartment owners also don’t allow their tenants to keep pets, but it doesn’t stop people from being pet or animal lovers.
Japanese also work long hours making it difficult to take proper care of their pets. I remember having to feed my bosses cat when they were on holiday and even though their apartment was a decent size, the place smelt of cat you know what.
