I have a funny cat story, vampirequeen, relating to a no cats allowed tenancy.
I had my cats from when I was married. I wasn't getting rid of them despite going into rented accomodation when I left my husband. So everytime the letting agent came round to do a check, I put the cats in their vet boxes and put them in the car.
On the final occasion, I got fed up with doing it, so just shut them outside. The agent NEVER checked outside. Except on this occasion, he wanted to. AND it was raining. So the cats heard the door open and streamed in (all 4 of them).
Had to pretend they were the neighbours cats and shoo them out again. Have you ever tried to herd cats?
