The talking cat of Speke is an old legend in speke and halewood. I heard it years ago in the seventies. Cats have been known as 'familiars' i.e. attendant demons of witches.
As for John Magin Kennedy - I asked him once if he believed anyone had left his grave and drank blood, and he said, 'They based a whole religion on one. His name was Jesus.'
I thought that was a bit out of order though, but, s'pose he has a point .
