To eat, perchance to poop

Everyone keeps telling Mommy to take me to the vet because I insist on crapping on a special spot on the living room rug every two days. Whether the box is clean or not, I default to my favorite spot, and everyone seems to think it's a medical condition.

Look, under Cat Law, I am expected to:

1. Sleep as much as possible
2. Shed, preferably onto Mommy's dark work clothes
3. Eat everything put before me
4. Poop, bountifully and plentifully
5. Wipe my ass on the floors, walls and other stationery objects so that I do not have dingleberries hanging from my long fur.

How can you punish/heal a cat for doing what the Kitty Gods have put her on this earth to do?!?!

Mommy's so fed up, she's decided SHE is just going to crap on the floor too because the house already smells like my ass. Hey, that's MY job!!! Shit, if she's gonna be wiping her ass on the floor too, I might as well just use the litterbox just to be a rebel!
