Thanks for the replies everyone, except you've all got me even more worried now!!
I actually popped into the vets on my way home yesterday and managed to have a quick word with the vet. She said as they're not showing any interest in each other yet (still too interested in da birdy, ping pong balls, climbing curtains and eating
), and also that most cats tend to breed in the spring, then not to worry too much, and they should be fine. I know that's not guaranteed though.
Helen -good idea, I hadn't thought of that
Thanks
