The Science Behind Why Cats Come Running to "Pspsps"

Okay, so maybe it's not phonetically correct but that whispery "pspsps" we all make to call our feline companions over is actually considered to be a universal language among cats. And guess what? That's science speaking!


Yes, we've all seen how that blend of a hiss and whisper acts as a sure-fire way to draw the attention of a snoozing feline. That head turn, ear swivel, or whisker twitch from the most seriously aloof, and totally independent cat, is a dead giveaway. I know. I live with two of them.


But what's cool, is that science has picked up on this and decided to dig a little deeper to understand what actually makes this indiscriminate sound, so appealing to our furry friends. And what they've determined is that it's less the word and more the hissing sound it produces.


According to Susanne Schötz, PhD, a phonetics researcher and author of The Secret Language of Cats, felines have more than 20 muscles in each ear which makes those appendages remarkably mobile and quick at honing in on any out-of-the-norm sound they pick up.


Add to that a listening range that reaches far beyond that of humans (85 kHz versus 20 kHz) and it's no wonder that even when napping, cats don't miss a thing.


But with lots of sounds going on in a house, what makes this one so compelling? Well, it's different from those they hear on a day-to-day basis. That means it breaks through the usual "noise" and becomes something that's instantly worth checking out. Hey, I'd be the same.


Here's where it gets interesting. The specific sounds in "pspsps" carry high pitches, and the S, TS, and C sounds fall into a range cats are especially tuned to. Rodents communicate at high frequencies, and cats evolved to detect exactly those subtle squeaks.


"High-pitched squeaking vocalizations are roughly approximated by the human 'hissing' syllables s, c and ts," says Péter Pongrácz, PhD, a professor of ethology at Eötvös Loránd University. That helps explain why "ksksksks," which author Schötz uses to call her own cats in Swedish, works just as well. The sharp, high-pitched quality seems to matter more than the exact phrase.


Pongrácz explains that this seemingly innate method of connecting with our cats likely has cultural roots. "People developed long ago these types of cat-calling noises that we learn culturally from our parents, grandparents," "Pspsps" likely evolved as a shortened version of "Here, pussy, pussy, pussy," trimmed down to only the sounds that actually work.


Cats are also quick learners and respond well to positive reinforcement. If a cat repeatedly hears "pspsps" followed by attention, affection, or treats, it begins to associate the sound with something enjoyable, and over time the response becomes almost automatic. That helps explain why one cat sprints across the room while another barely lifts an ear. Every cat brings its own sensitivities and past experiences.


So, if you've managed to find this one simple yet effective method to capture your cat's attention, having treats on-the-ready is he way to continue the tradition.
