My cat, Jitterbug, just gave birth two four kittens the night before last. Everything seems to be going well, except there is poop on the kittens' legs and tail. Jitterbug grooms them everywhere else but there. Also, she is very protective of them. I tried cleaning one of them with a damp cloth, but the poor thing makes such a fuss, and I couldn't get it all off, and Jitterbug was having a conniption. What is a better way to do this?
