The baby is so big for 4 weeks! Just looking very big in your hands.Here is one of the babies...the little poops are like cement! I am trying to just work them out of the fur with cornstarch, but I feel like a comb would pull out the fur...
If you can't remove them you can cut them off. Because their skin is so thin and I don't want to cut too much or into skin, I place baby comb between skin and poo and cut with nail scissors between baby comb and poo, that way is safe I am sure not touching skin at all.
I use nail scissors because the ends are not sharp so in case they move suddenly it is safe, you can also use scissors with blunt ends.
