If he even comes back into the area... I've been changing the area a lot which cats hate. And the tarp is rustling a lot which could be offputting

I'm doing too much but have been getting genuinely anxious over this cat.

It was raining and when it slowed to a drizzle he went past in all the wet. At night. (My council has a cat curfew.) There’s also a flattened area in a nook under the eaves which he may be using as shelter.

Afaik he’s “owned” but there’s a lot of owners who let them live as outside cats and do jackshit to care for them. And it has happened before that a previous cat was suddenly coming to me much more because his owner had moved away leaving him behind :(
