well, downstairs neighbour couple have known her all her life and they say she's definitely not spayed yet, nice as that would be.

I suspect this is why the ex-owners dumped her on me this way without so much as a phone call. Wankers. I hope to hell she's not too far along to get spayed anyway. She's not very bulgy and I can't feel distinct shapes in there or anything.

She really does not need to be dealing with kittens on top of everything else at her age.
