Oh Koxka!! That is so exiting - do you intend to keep them? Have you looked for the mother around in the area? It's quite a task you have taken on, but I'm sure you can cope! Feeding them the right food is probably the most important at the moment and keeping them warm, of course. I have no idea what else you can do, but I'm sure someone on PT will know a few things about the subject.

Oh, you better keep them away from your other kitties in case they have an infection!

Can't wait to see pictures of them. All the very best of luck!!
