The other day, my cat accidentally clawed my finger (the pinky) and it was actually a pretty bad little split (I think it's a bit deep) it bled at first but I cared for it properly by cleaning it and always wearing first aid tape on it but today when I was changing the tape, the skin (only the part of my finger that has been covered by the tape) is kind of white and a bit pruney(or wrinkly). My question is, why does it look like that?
