She's called Izzy and is a tortoiseshell and white shorthair. I'll do a photo when I get a chance - Bonzi of course doesn't know yet that there's a another female here to nag him, but he'll find out when he gets home. She's busy (I know busy Izzy but I didn't name her) exploring the place. I hope within a few days they'll have settled down together without blood on the ceiling.
She's a rescue cat who suffered head injuries in a road accident yet still managed to carry three kittens and birth them, so she's made of tough stuff. They've been homed and I've adopted the mother. We think she's a year or two old at most. She's very affectionate and nosy.
