Digging in,... litter?

It's not the first time I've seen mommy do this. She picked up a large square spoon with holes in it and dug through my litter box to find every stinky object I've buried in there. I personally believe the stuff that comes OUT of my body is smelly and it is embarrassing to think anyone would have to smell it or see it, but mommy insists on digging for it every so often! Why on earth would she do that?

If I really stop and think about it, she did recently get a cage-mint ring. Maybe she needed it because she does smell the stinky scent even after it is buried, and maybe she's trying to find it and get rid of it? If that's the case I feel even more humiliated! After it seemed she found all the little treasures I left behind, she then took my whole litter box and dumped out all the sand! Great, what was I supposed to use now?

Mommy sprayed some bad-smelling chemicals on the litter box and scrubbed it to made it look brand new. What she did next however, was definitely strange and new,.. she opened a small box and pulled out some plastic sheets to lay into the litter box pan. It sure seemed like a hard job because she took some time putting it right in the center and tying it down with a stretchy hoop that came with the sheets. Finally, she poured in brand new sand for me! It all made sense then, she didn't like the smell of the sand. Maybe these plastic sheets will help bury the smell of whatever I bury in there. Good. This way I won't be embarrassed anymore, and none of us will have to suffer with the stinky stuff!
