While I can't see any harm in a cat cafe, I just don't understand what makes it so different from a shelter except that shelters don't sell you coffee while you are visiting the animals. My only concern would be that people who already have cats that may have gotten them on a whim, will decide to dump their cats on the cafe and not being a shelter, the cafe will reject a lot of the dumped ones. What happens to them? I would also be worried about someone who is not a cat person, engaging with the cats and inadvertently (or purposely) antagonizing one and the cat lashes out, next thing you know the client complains and the cat is put on death row. Wouldn't there be a constant drive to get cuter and more personable cats? What happens to those who don't make the grade? I just think that maybe this is something that is best left to the shelters. If people want to play with cats or pet some cats, there are plenty just dying for some attention at your local shelter.
