Some people want to live with pets in rental apartments, but many of them prohibit having pets for some reasons like cats and dogs smell bad, damage the walls, or they are noisy.
However, apartments with cats are gaining attention lately. If you rent the apartment, a cat comes with it, and you can also adopt the cat.
An NPO, Tokyo Cat Guardian, started this project that protects cats from being euthanized, and even if you have never raised a cat, you can live with it, if the NPO judges you can raise it.
There are many dogs and cats being euthanized in Japan, but if abandoned dogs and cats find safe places where there are responsible people who can raise animals, the issue of abandoned pets will come closer to resolving.
