There's a cat been hanging around my garden the last few days, that doesn't appear to have gone anywhere else in that time that I've noticed.
She keeps coming through my catflap and eating my cats food, til one of them catches her and sends her packing!
I've been around at all kinds of funny times of day and night, eg the other night was up til 3am, went out to see if it was snowing and the cat was still there then. It's been around day and night for a few days.
She seems quite plump and well looked after though, groomed, with collar that has a little bell on.
I don't know what to do?
If she is lost or abandoned I will take her up to our local charity I suppose but how can I tell for sure?
Plump, well groomed and with a collar sounds to me like she's got herself lost or something is untoward about her situation. (Rather than a pure stray.) In this weather, I wouldn't have thought that owners would purposefully leave her out all night.
Maybe ask around the neighbours just in case they know her?
I'd ask around neighbours and maybe give the local vet/cat rescue a phone to see if they've any reports of a lost cat. Then if she's still around tomorrow or Tuesday, see if you can catch and box her and take her to the vets (road conditions permitting) to see if she has a chip.
In the meantime - does she have somewhere out of the weather that she could sleep if neede? (Say a garage or an outhouse where you could put down an old box of blankets or towels etc. You could get her to go there with nosh.)
