Aw that is awful I would take her in a heartbeat if I could! We are in the middle of house hunting at the moment and if everything goes to plan we should be in our own house in 3 months from now. We could definitely take her then for as long as you need. It's just in the meantime we can't because we are currently living with my mum and already have a cat here who is NOT friendly to other animals

I really hope someone can help you now, and if you need someone to mind her in 3 months time we are more than happy to.

I know what you mean about lack of space, but maybe try to convince your mum that kitty needs rescuing or things might be looking grim for her, and it's just a few months!
