Agreed! Decades ago I had a neighbor ask me to look after her 3 cats while she went on a five day vacation.. you know, feed em, fresh water, scoop the litter pans.... Day 1... of a non cat person... scooping a litter pan.... the smell. Ohdeargawd..nauseatingly stinkified. I gagged my #ss off scooping that nasty kitty crap..almost throwing up, eyes tearing up from gagging and of course... the wet your undies thoroughly from the hard gagging. I don't know how I made it through the next four days. Trying to only breathe through my mouth so I wouldn't smell it didn't work... I already had it in my brain. Never did that again!!!!If bird poop smelled I wouldn’t have birds!
