This is much like the cat who lives in your house covering up their poop in the litter box. At first, you are not aware that a cat has been there. But soon, you will be convinced that a cat MUST be in you house because there is a stench from the littler box that can NO LONGER BE IGNORED. We are there. The only way to remove the stench is to clean out the litter box. The permanent way to eliminate the stench is to remove the cat. No - I am a cat lover. Just remember when you have a cat living in your house, the litter box will require constant maintenance. WE ARE ALSO THERE WITH THE DEMS.
