I’ll keep an eye out. The cat I think you’re talking about I’ve seen in my front garden. Though she spends most of her time on Wynell she also goes to April Glen.
I own one of the other black cats without a collar in the neighbourhood, but she’s spayed and shorter haired. Will upload a picture when I have a minute to discourage confusion.
Would also happily volunteer to give the kitten a home if found and owners of Mum don’t want her.
