You are probably familiar with the feline behavior amusingly termed “elevator butt.” Stroke a cat along the length of their spine or scratch them at the base of their tail, and they are likely to stick that posterior up in the air. My parents’ cat, Rosenberg, actually stands all the way up. It’s a foolproof way to get her out of your spot on the couch. But, why? It’s a pretty weird thing to do. When my friend asked me to find the answer for her, I honestly didn’t think I’d be able to. I mean, yeah, I wanted to know, too, but would there really be any behaviorists out there devoting their brains to the mystery of why cats raise their butts when you pet them? Sometimes I’m thrilled to be wrong. Not only did I find answers, but they’re really quite interesting.
The Importance of Body Language
Cats can’t just tell us how they feel, but they communicate a lot without words. One reason your cat might lift their hindquarters in response to petting is to tell you “oh yeah, that’s the spot–more of that please” (3-5). They’re leaning into the pleasurable sensation (1, 2). The hips and base of the tail have lots of nerve endings, so many cats really enjoy being pet or scratched there and want to tell you to keep going (1, 2). It’s also difficult for cats to reach those spots when grooming, so you may be scratching an itch kitty just can’t reach on their own (1, 2).
In addition, cats present their rears as a friendly greeting (1, 4, 5). Another cat would sniff the scents coming from their anal glands to learn more about them (1). Your cat probably knows from experience that you won’t put your nose under their tail, but their instincts still tell them that a raised butt communicates trust and friendliness (1).
By the same token, cats may exhibit this behavior as a way to mark the person petting them with their scent from their anal glands (1, 2, 5). That may sound gross, but it’s similar to when cats rub you with their cheeks, another place where they have scent glands. They just want to lay claim to a favorite person or someone who is making them happy by petting them in just the right spot (1, 2, 5). The pheromones from a cat’s scent glands are undetectable to the human nose, but other cats can smell them and tell whose human you are (2).
Are You My Mommy?
There is a theory that cats raise their butts in response to petting as a holdover from when they were young kittens (1, 2, 4, 5). Kittens aren’t able to do much for themselves at first. That includes grooming, which they rely on their mothers for until they get the hang of it. Young kittens stick their posteriors in the air so their mothers can clean them (1, 2, 4).
Our pet cats have a complex relationship with us in which they view us partly as surrogate parents (1, 2, 4, 6). When they feel their person stroking their back the way their mother’s tongue once ran down their fur, they may react the same way they did as kittens.
But What If…
…My Cat Doesn’t Do This?
If your cat doesn’t put their rear end to the sky when you pet their back, it doesn’t mean they hate you. If you just got your cat, it could be because they haven’t quite warmed up to you yet (2). But some cats just don’t enjoy being pet around the base of the tail like others do. The concentration of nerves endings that makes it feel so good to a lot of cats can actually make it unpleasant for others (1, 2). Other cats may like a little petting in that sweet spot but quickly become overstimulated (1, 3).
If your cat used to get elevator butt and really seem to enjoy those back scratches, but suddenly they don’t, or your cat seems to react with pain when touched around the hips/tail base, this could be cause for concern (1, 2). Skin allergies, impacted anal glands, spinal problems, and kidney disease can cause pain in that area (1, 2). Take your cat to the veterinarian if you notice any signs of pain in their lower back.
…My Cat Does This Without Being Pet?
If you have an intact (un-spayed) she-cat, you may notice that sometimes she gets elevator butt not only when you pet her, but apparently out of the blue. This is called lordosis and is an indication that a she-cat is in estrus, or heat (2, 3). Lordosis looks slightly different from regular elevator butt because it’s actually the she-cat presenting herself to a tom for mating–whether a tom is present or not (2, 3). She turns her tail to the side and may tread her hind paws (3). She cats in heat will usually do this a lot, including almost any time they are pet.

why are you calling it “she-cat” just say female cat.
Because that is what people call female cats. They’re more properly called mollies (in the same way male cats are called toms), but I have never heard anyone use that term in real life. And “female cat” has another whole syllable and three more characters. Why would I do all that extra work?
From my understsnfind a “she-cat'” here means a Queen AKA: an unspayed or intact femal cat
Excellent!
Too many syllables was Exactly the reason I changed my Echo Dot’s wake word from “Alexa” to “Echo”. 😀
😀 Thanks for answering my question! I figured it had something to do with the nerve endings, but I didn’t know about the kitten behavior or the possibility that cats use elevator butt to scent mark us. I wonder what cats think of us and our general disinterest in presenting them with our behinds.
