Thanks for all the advice!
Yeah my room is huge, plus they have the run of the house during the day. I've got fairly good insurance with Sainsburys at the minute, so for two cats it'll cost me about £13 a month, and it's £50 excess. Which isn't too bad? I've found a couple of breeders that have seal colourpoint raggy girls, so fingers crossed in a few weeks I'll have two crazy balls of fluff!
