Sorry for the delay in updating, I have had a manic (non cat related) few weeks.
So! I can't remember if I told you but I had contacted Cats Protection for advice, they told me to tell her about the neutering and speying programme for £10.00. I gently broached it with her and gave her a leaflet - said it came through my door but my boy was neutered at a few months old so not needed.
She was pleasant enough but I sensed some attitude from her. She said the cat is not pregnant as had been kept in.
I kidnapped the cat and took her to the vets, she is not microchipped. She isn't pregnant but had a belly full of worms. I got meds and gave it to her.
I didn't see the cat for about 2 weeks, then she returned with a shaved patch on her side, she has been speyed.
I was getting out of my car last night and neighbour was getting out of a mutual neighbours car (mutual neighbour was previously moaning to me about the cat and I had a bitch back, saying that I feed her all the time). Cat owner declared loudly as the cat approached "come on whiskers, give it a rest, you've had your two meals today" and gave me a look.
So it appears I have made a bit of an enemy out of her lol Going to monitor the situation before making any decisions, see how often she is left out in the winter. If I was to take her now, she would know its me, and at least she has had her speyed.
Until then, there will always be a warm spot on my sofa, and an open window.
