HELP......I rescued 2 about week old kittens yesterday. We are getting snow and is very cold and windy. They would have died. I have a female cat who birthed a litter of 4 kittens 9 weeks ago and still is producing milk. Would it be ok if I could get her to nurse these kittens? I need suggestions on what to do until I can get out from this snow and get nipples and kitten formula. All suggestions welcome please
