A strange cat has turned up in our garden. We know most of the cats hereabouts and this one's new. It's a sweet little thing - tortoiseshell, very skinny, quite friendly, and very loud-miaowed. It was insistently howling at our conservatory door yesterday; I gave it a bit of food and it wolfed it down. It was still there by nighttime, and I was a bit worried about it, so I put some food and a cardboard box with bedding into our greenhouse, to give it a bit of shelter. It's still there now. Poor little scrap, when I picked it up to "show" it the bed, it was light as a feather.
If we didn't already have two huge thuggish tabbies I'd invite it in 
What's the best course of action if it's still here tomorrow? Ask around the neighbours, or ring CPL? (Our immediate next door neighbour didn't recognise it either.)
I don't think it's a feral (we have a few round here) as it's so friendly.
