At Wensum Lodge in Norwich we have a little cat that frequents the buildings .. a beautiful-looking ginger and white cat.
I did wonder at one time if it had been a teacher or student in a previous life as it seems to spend most of the day there, though it has a very nice home of its own. We keep chasing it off in the direction of home as it's owner does miss it, but to no avail ..
It always yeowls and miaows to be let in and we have to be very careful to keep an eye out for it so it doesn't sneak in as if it does get in it poops in the rooms given half a chance which the poor caretaker has the job of clearing up !
