Cute sign, but I'll pass on using it.

In my house poop outside of the box is usually a welcome thing for several reasons...

1) I have a Megacolon cat (Jack) who any poop out of him is a good thing.

2) Usually if Jack is getting a bit constipated I up some of his meds and in a couple days he poops, it's usually outside the box when he does, and it's HUGE.

3) Poop is MUCH easier to clean up than the cat pee from my two urinary problem cats.

While it may be annoying to have poop outside the box, you can see that in my house it's not such a bad thing. lol
