*Apologies for the terrible quality!*
Took them home in a box as its freezing outside and dogs frequent the path the mother cat was on, so now I have three kittens and a mildly aggressive but otherwise friendly mother cat in my living room awaiting the local cat shelter place to open so I can call, don't know if she's someone's pet but I guess if she is, she'd not be out there alone with no collar, and we'll see if she's microchipped or not!

EDIT: Vets came, kitties have been taken away safe and sound! ^w^
