My sister has a pregnant stray cat living in her back yard. She(the cat), is scared of people, if an animal shelter picks her up, they will most likely put her and the unborn kittens to sleep..that's what I've heard... and the coldest months of the winter are coming, so the kittens may freeze. My sister has food out there for her, which she eats and a heated outdoor cat bed but the cat(kit) won't go near the warm bed even though it has been there for a good month now. When the kittens are born, we don't know what we are going to do...any suggestions?
