Chimps prefer peeing together, 600 hours of study shows

Years of 'studying' homo sapiens in bars has made me keenly aware that while the female of the species does urinal visits preferably in groups of 2+, the males abhore any joint visits to the bathroom facilities and will go out of their way waiting for the previous guy in the group to return from the bog before venturing forward themselves.

This is true

Does not apply when cocaine is involved, per observational research in other venues.

Writers for TV know this very well. Notice how it's a trope in many sitcoms and dramas for two women to visit the restaurant ladies room at the same time when one of the men they're with makes a faux pas.

Original study: https://www.cell.com/current-biology/abstract/S0960-9822(24)...

It's worth noting that the chimps were in captivity, so it's not like there were researchers crouching in a bush in the jungle watching chimps pee for 600 hours. At least not for this study.

Strength in numbers. Same with defecation, eating, sexual activity, sleeping. Any point at which you'd be vulnerable to missing that predator. That's why tribal species like ours have thrived.

So true. When backpacking we'd bring a buddy to watch your back when you go pee. Better not make it easy for a mountain lion.

Youtube science has also told me that's also why cats want to bother you in the bathroom.

Never really was a cat person growing up (I still contend most of them are just straight up evil villains and just plain mean lol) but after a short battle with some mice that tried to move into my house last year I decided to adopt one. She's a very cautious cat (rescued alongside 20 other cats being neglected from some degenerate) and walks around like she's in a mine field all dainty and shit.

After the toilet seat makes its noise from being put down, that cat will be standing at the door before I've even had a chance to sit down regardless of where she was. The one time one of my kids used my bathroom I finally got to witness that little scaredy cat temporarily morph into a ninja and parkour her way from a back room, clear my recliner, use a door mat/rug to be able to take a 90° turn into my room at full speed (hard floors in most of the house makes for some funny antics with both the dog and cat lol), keep running all out and jumping into the side of my bed and using it to make another full speed 90° turn that after she landed had exactly the right amount of momentum to slide to a stop right in the doorway. The same cat that is still petrified of walking on the counter in front of the kitchen sink has no problem at all vaulting around the house if someone is going to poop in my bathroom.

All this to say, I'm kinda sad now, I thought I had found another being in this world who thinks my shit smells like roses too!

I know who's winning an Ig Nobel this year!

cause scent marking via pee is a species universal territorial act?
