My snakes eyes turned blue 2 days ago when does he actually shed his skin? also his humidity is between 60-70% in the humid hide. The normal humidity is around 58%. I have kept handling the same should i stop for the shed? Also my snake has a small skratch on his stomach about 1-1/2 cm long. I took all sharp things out of the cage to dull it all down what could i do about the scratch?
