Oh no, I've been rumbled!
It is me indeed.
A relative of the woman in question is one of our supporters. She went last night to set the trap again after receiving instructions via text from me (I was sat in the vets most of last night waiting my turn). So we are keeping everything crossed that they will be successful today in catching her. If they do catch her our vet will keep her in and treat her as required, that side is already sorted out. If not, I use Program for my more timid ferals anyway, so I can provide that for her, not be a problem, at least it would make a start.
There probably is a pattern to the cat's appearance but I don't think she is really aware of it, she just puts a dish of food out and it either goes or doesn't. She is not a cat lover in particular, but as she feeds her and feels sorry for her, she can't be all bad, although I can't imagine her taking notes for me!!
Thanks for the advice though. Much appreciated. Glad Katie is doing fine. She's a very lucky girl!
