When K. Jnr was little, we had a succession of au pairs. Most of them were lovely and my old cat, Cleo got on fine with them. Then we got a bloke (well, he was supposed to be a bloke, but he liked dressing up in womens' clothes & was like a great lump of lard - but hey, that's another story!). Cleo LOATHED him and I told him to keep his bedroom door shut,( because I knew what she'd do!) Anyway, one night he left his door open and at about 2a.m. he woke me (Mr. K was on night shift), saying, "I've got something to show you." Well, you can imagine what I thought, but no - I went into his room and he had the mattress propped up against the wall and all the bedlinen in a heap. Cleo had gone in, in the middle of the night and pee-ed on the bed with him in it!! I had to try not to laugh! He went back to Hungary shortly after that & Cleo never upset another au pair again!
