Hi, please don't take that wrong way. I wasn't trying to say you weren't doing it right and contributed to the passing, it was just helpful pointers. And sometimes I will even admit that they just don't get all the skin and you have to help them out, and when it happens with mine its always the back legs like yours was. And I just do the same thing, drop in a bath wait for him to get nice and wet and just peel it for him.
