A woman asks about cats. She would like to do something to help them. She doesn't tell us what kind of help she would like to provide, but it is a reasonably safe assumption to think she wants to help homeless cats, the ones that gather in any neighborhood where residents will give them food. Mine is especially popular. We have many cat lovers and the wild, scraggly strays eventually are transformed into clean, well-kept cats that can be counted on to produce the next generation of kittens without a home of their own, dependent upon charity.
Authorities, as well as sincere cat lovers, do not want people to extend this kind of care to homeless cats. It only leads to increased problems down the genealogical line. They want concerned cat lovers to catch these cats and take them someplace to have them neutered. This can be a financial drain because vets charge high fees for this service. There are times when public concern results in bargain neutering being made available, and often ward offices will have a list of cooperating vets. Then the problem may well be how to catch a cat that does not want to be caught and get it to the cooperating vet.
Since we cannot be sure what she wants to do, I would suggest that she buy a copy of a magazine called Cats. Only the title is in English so if her Japanese and imagination are not good enough, she must find a friend to help with translation. There is much information about cats including cat clubs and organizations.
