Hi, I'm really hoping someone out there can help me. My children found a baby kitten in our back yard two days ago. We estimate that it is about three weeks old. It's eyes are open and its walking (wobbly) on all fours. I have been feeding it milk replacement that we purchased at our local store. My concern is the fact that it seems to have a cold.??. The poor little thing has trouble breathing and the first day it was inside, it had greenish snot coming from its nose. The discharge has stopped and she is eating pretty well, but the labored breathing continues. Can anyone suggest something I can try at home until I can get her to the vet??
