I think that a cat cafe would be a great way for abandoned cats to get adopted. For the nice cats, they get contact with people who might fall in love with them and adopt them. The less friendly cats will get used to being in the presence of being with humans and become more friendly and then hopefully will find a home. In the meantime, the profits from cafe plus additional donations can go to letting the cats live comfortably without the threat of being put to sleep after two weeks. It could be a great addition for shelters to loan out cats to get adopted, switching out cats every week to give them a break and introduce new cats into the public. This also would put less stress on the people who love cats to come and visit a cat to play without committing to getting one if they can't afford one or live in a small studio apartment.
