Ok well the second soak was much nicer. Got about 90% of the remaining shed off.
She's still got some lingering skin under the neck. And a little spot past that. It just wouldn't come off.
Thoroughly disinfected the whole tub while she soaked. I will probably try 1 more time tomorrow after work.
If I can get a little bit more off ill be happy. If not then it'll have to wait.
