They do.

Cats like to turn around and stick their little puckered sphincter in your face, usually with shitlets around it. Dogs often are the same way, wagging their tails and they fart lots too.

Fish swim around in their little tanks with steamers of fish shit dangling from their bums... humans have pasty white asses unless they tone them up and tan them... even then though...

Cows poop out big runny things of shit in jet streams... leaving it dribbled all down their legs.

Horses on the other hand... They keep their tails modestly flattened over their assholes, they have a nice rounded rump that you can pat without having to worry about shitlets... And when they do poop it doesn't run down their ass (If it does they need to get a check up) and as an added bonus, when the shit dries it's the perfect density and weight for chucking at someone's head. LOL

Can you tell I grew up on a farm and am bored senseless?
