makes me laugh, there are so many people on here that have their cat's sat next to them when on the loo (including me)
Bonnie sometimes jumps in the bath and has a walk around it while I'm on the loo but never tried to have a wee in it.
However, my first cat Tibby who was pts when she was 26 years old as she was dying at home, she always used the bath plug hole in her last few months of her life.
Good luck.
