I have not checked with any of our shelters here, but I think most new zealanders at least the sane ones, don't have this stupid superstition about black cats, infact I think they are considered good luck here.

However I agree with your shelters doing that, very responsible, I cannot believe any human would believe a black cat has a witch in them ,good grief some people

If anything my lil Lexie has an angel in her, nothing else.

Sad to think, in this day and age such silly ideas are still believed.
