I found three kittens today and they were in a box and it was raining so I brought them up under neath the stairs outside.. When I got back home after picking my brother up, two were gone and the runt was left. The mother came and knocked over the box and left the other one, and I think there might be something wrong with it. It can't be more than a week old and I don't want to touch it because I don't want it to die. I want to bring it in from outside because it's hot and rainy and if the mother doesn't come back soon, I will, but I need to know what to do. I don't know whether I should leave it out all night or, bring it in and keep it warm and maybe feed it evaporated milk.. Please help me and let me know what I should do.
