My Cat Poops In The Bathtub!

I hate to be so blunt, but it is true! Luckily I have two bathtubs, and it is not the one I use. I started out with a regular litterbox, but she would fling the litter around on the floor so much, I got one of the hooded varieties. That prevented the flinging, but that is when she started poopin in the tub! I googled this phenomenon and found out that this is not that unusual--that some cats do do this (no pun intended) all of their lives. I hope she is not one of them. After several weeks of this icky behavior, I went back to one of the regular litterboxes again. She is now flinging the litter, but hopefully there will be no more poop in the tub. Thank goodness she is cute and otherwise sweet.
