Thanks for your message. As you can see, I edited it since we do get some kids in the Forums, and I don't like for them to see a lot of that kind of language ... thanks in advance for remembering that in the future.
As for your problem, my first suggestion when inappropriate litter box habits sprout is always to take kitty in for a thorough vet exam to rule out health issues. Once the vet gives your kitty a clean bill of health, I would take away that Stick-Up and don't put it back near the box - it could be your kitty doesn't like the smell of it and won't potty there. Second, I would try a different location for the litter box, and third, I might try a different kind of litter.
Above all else, be patient with kitty and keep trying. You will eventually find out what the problem is and can work to correct it.
Continued best of luck,
