Cats can be selfish jerks, but the fact that they’re willing to groom each other shows they have a selfless side too.
Doesn’t it?
Not so fast, say two scientists from Belgium’s Ghent University.
While allogrooming — animals socially grooming each other — is a sign of community, alliance and social bonds in other species, apparently cats have found a way to weaponize it.
By analyzing footage of cats grooming each other, the Belgian team confirmed cats groom the way other animals do, signaling closeness, trust and all that good stuff…most of the time.
But they also use it to seriously piss each other off, usually to take possession of territory they covet.
“I saw these weird grooming patterns in my own cats where I thought, ‘This is not super friendly at all,’” Morgane Van Belle, a cat behaviorist and co-author of the new study, told the New York Times. “Sometimes one cat would lay on the blanket near the window and the other cat would come up and start licking it — but in an annoying way.”

The aggressor cat is hoping the other feline will get so annoyed with the invasive grooming that they’ll abandon their prize spot, whether it’s a sun puddle or a particularly comfortable spot on the couch.
The study’s authors believe there’s more to learn about this behavior, and understanding it can help people mitigate conflict among their feline overlords.
For readers who have multiple cats, have you witnessed this behavior?
For what it’s worth, allogrooming between cats and humans is a thing too. For example, I brush the Budster, and he grooms my hair when I’m in bed.
Some people find that gross, but I try to take it was the compliment it is. Thankfully I have not been subject to weaponized hair grooming, but I’ve seen examples of the behavior the Belgian researchers have identified, and once you realize what you’re looking at, it makes perfect sense. Taking a normal behavior and turning it into an instrument of annoyance is also a very feline thing to do.
Cats show great ingenuity, so we’re fortunate they’re extremely lazy. If sufficiently motivated, they could undoubtedly rule the world.
