Second night in rented first floor flat. Went to the loo, as I was sitting down something caught my eye at the side, as I turned to look a HUUGE rat ran along the side of the bath towards me/the toilet. I screamed and ran out and it went behind the toilet. DH and I cautiously went back in (once he had recovered from the sight of me running out of the bathroom straight into the living room with my trousers and knickers round my knees!!). As we were discussing it, the rat peeked out from the cavity behind the toilet. Short term, we have barricaded the cavity behind the toilet with thick cardboard and shut the door and stuffed the gap under the door with cardboard. Can't get hold of letting agent. What happens now?
