Why would anyone want a cat as a pet?

Ha Ha .... I hate cats, they catch all my wild birds and give me hay fever, they sleep on your bed and furniture and leave hair everywhere. They jump on the counter/table and eat your food, the sleep on top of babies, the domestic cat is the cause of the extinciton of hundreds of different species world wide. Oh yes and they carry a terrible incurable disease toxioplasmosis ... deadly when humans get it.
