My next door neighbor (in her 90's) has a hole under her house where 4 little kittens about 4 weeks old popped out this afternoon. My cat has 4 week old kittens and they look about mines age. I would try to help them out but there covered in fleas! I did feed them kitten food and they ate. We havent seen a mama cat. They seem ok just extreamly hungry. I can not take them in. I do NOT want them in danger. Plus I cant get all 4 out from the house. What can I do?
