We have a giant Norwegian Forest Cat, 22 pounds,
strong as an ox and solid as a rock, and since
he was "little" he quit crapping in the litter box
altogether. He follows me into the bathroom
and craps on the floor while I'm doing my business.

He DOES pee in the box though. Thank God!

We've tried EVERYTHING, and finally just accepted
this behavior. Other than this he's a sweet, gentle
moose, with a coat so long it drags on the ground,
a lion's mane, and pretty as can be.

He never claws the furniture and he's a GREAT mouser
so sometimes you just have to live with
another's idiosyncracies.
That's what my wife tells me.
