Or maybe it is just exactly what it often looks like: a sign of happiness and exhilaration.
In humans, the vagus nerve, which descends from the brainstem to the colon and is stimulated during defecation, can cause all kinds of reactions, even feelings of exhilaration, according to gastroenterologist Dr. Anish Sheth, who wrote " What's Your Poo Telling You."
A similar phenomenon could be occurring in cats and could explain why cats seem elated and happy, running around and scratching their scratching posts with joy, Erin Willis, animal physiologist at Oklahoma State University, told The Dodo.
"Dr. Sheth calls the pleasurable sensation with defecation 'poo-phoria.' Good name for humans I guess, but the term 'poop crazies' is much better for cats, in my opinion, since they essentially run around like crazy cats afterwards," Willis said, adding that there is very little research on the matter.
