Second worst. Pig is worse. Liquid pig litter will do the job maybe too much.
Stink in order from least to worst...

But it all stinks.

You sure seem to know your shit!
I was raised on a farm! Raised pigs and chickens and cows and horses. Soon learned to distinguish what I smelled by the stench of the odor. Never forgot the smell.
Now I live within a few miles of a human sewage treatment plant, and some farmers spread it on their land. It has a sickening “sweet” smell to it.
Raised around it, shoveled it, hauled it, spread it. I know it so well my name is associated with it!
On the other hand I have no problem with dog or cat poo except when I step in it and it squishes between my toes.
