Delighted to hear Janice is back; what a relief.As you might have read: she back!
I don’t think the cat is feral. Real feral cats are a bit bigger. And this one looked very healthy and looked after.
If I set out a live trap for cats, I need to check several times a day. There are 4 neighbouring cat’s hanging around in our garden every day. 2 at night too. One neighbour has a 24/7 pop door for cats. They behave as if our garden is theirs too. Not so strange, bc I feed them when their owners are away on a trip/vacation ( = quit often).
And beside these 4 there are more domestic cats in the neighbourhood, I wouldn’t like to harm.
In our previous house we had a problem with local cats using our garden as a toilet, and someone told me a tip for a deterrent that worked (though none of us know why it does). Get a 1.5/2 litre plastic bottle (the sort soft drinks are sold in) and half fill it with water. Screw the cap back on and lay it horizontally on the lawn. That's it. Worked for us; the cats stayed out of our garden while it was there.
