Squeaky crapped my pants! Smarty Kitty update

Squeaky crapped my pants! Really! Just in case you didn’t read my earlier post.  I bought “Smarty Kitty” off an infomercial when I was seduced by the idea of a cat using toilet, instead of the cat box.  Never mind that Squeaky had been happily using his cat box without fail for the entire five years since we adopted him.   Now, he won’t go near it, leaving surprises in the bathtub, on towels, on rugs, in my sewing basket……..I am frustrated by the mess and feel guilty for confusing him.  I’ve considered euthanasia, for me, not him, but that seems unethical since I took him out of a shelter and promised him a good home.
