Thanks I might see if I can finish work early in the next day or two and get a trap down to her and show her how to use it.

We can only get down at 7pm by which time it is pitch dark and no cats to be seen but Monday we'll can go out earlier.

At the weekend Steve is working and I am away to visit my depressed brother, I can't cancel it will make him worse.

I am both hoping that one she isn't pregnant and two if she is we catch her before the kittens are born.

We don't really have the space to foster another cat but if she is pregnant, she'll have to go in with Annie (after clear blood tests and vet exam) She lost the last litter due to the cold, so we have to try

Thanks for the tips, I'll let you know how things go.
