Dear the Mom,
A-hem. We haz something important to discuss with you regarding our litter boxes. We appreciate when you clean them out. However - it is NOT necessary for you to use words like "Stinky Makers" to describe the fragrances we leave behind.
Or to sing the "Stinky Stinky Stinky" song when you do clean them out. That's especially rude.
