Okay, this chick I'm friends with privliges has a older cat. (She will not get rid of cat, so that's not a option.) Here's the problem, cat is ****ting in the bath tub. She tried filling tub with water, works, cat using litter box, but she forgets too fill tub back up after bathing, and cat leaves stinky present in tub again. I came up with the perfect solution, let's see if you can figure it out.
