Anything that eats a ton of fish. Penguins are fucking awful.

Also anteaters. Anteater shit is horrible.

Humans.
Never get a pet human, even if it's the last thing you do.

Tegus or cats I'd say (IMO)

That is also only for smell.
If we are talking pure proportional mess, absolutely nothing beats a blood python.

A flock of Canadian geese. When they leave the ground looks like 10000 Chihuahuas came through the area.

TOP KEK!

I always hated my hedgehogs poop. It smelled horrendous and had the consistency of tooth paste

I never would have expected that.

Opossums and crows in my experience, and I can say I've smelled a lot of different animal poops.

Fish-eating snake poop is pretty awful.

My snake's shit usually dries out before I even notice it, but yesterday it was still soft and juicy and smelled like a homeless bum. Specifying bum here cause not all homeless people are trash.

For those who don't live in the city, it smells like a blend of shit, piss, saliva and dirty perineum.

Cows. OMG, it's so disgusting. It's like a sloppy puddle of nasty, stinking horror.
