Did anyone else watch the programme on BBC2 tonight, Beyond The Catflap?
We, too, have an 'interloper', who comes in and eats our cats food! Cheeky so-and-so! I have started to keep the expensive cat kibbles in the bedroom in the hope that it will put him/her off. It doesn't! S/he will come in and our two will just stay curled up on the bed. Hopeless!
