@Robert Gentel,
mmm....it's not all that strong in some cats either.
Jezzer takes a dump, then stands astride the litter box looking at it with distaste.
Then, she'll paw at the wall for a few seconds, then look down at the poop in amazement..."what? it's not covered up?" She'll paw the wall some more, then realize to be of any effect, she'd have to put her paws in the litter...puh-leeze, perish the thought. Then she walks off like nothing happened.
fortunately, otis has designated himself keep of the litter box and in fact buries stuff TOO deep. he's quite industrious. He's got job security with 3 cats around.
Lulu was the best. She'd unabashedly take a really stinkin' ****, and leave it right out there for everyone to admire.
