We are going away in a few weeks time and had arranged with a (normally very reliable and trusted) neighbour to look after our lovely boy. She's now informed me that her and her family have booked a trip away at THE SAME TIME as us 
MIL & SIL will both be away, we do have other neighbours but living where we do (London) only know them to say hello to. As it's school holidays the catteries are completely booked up as are local cat sitters. What on earth am I going to do?! I've never been in this position after 15 years a cat owner!
