Okay, so when I started taking care of 7 4-week-old kittens, I didn't know the KMR would dry like cement. Now all the kittens have nasty hard bits on their chins and bits of their fur. I don't know how to clean it off without hurting them, especially the hardened goatees they're all sporting now. I've been wiping them now immediately so I don't add to the problem but what's already been done has been done and I want to get rid of the hard bits. How do I do it?
