Why That Sound Actually Works On Cats
It's not magic. The "pspsps" sound you hear everywhere is just a high-frequency tongue click against the roof of the mouth while blowing air. Cats have an incredibly wide hearing range, roughly 48 Hz to 85,000 Hz compared to humans at 20 Hz to 20,000 Hz, and that particular frequency band is what triggers their predatory attention instinct. When someone makes that sound, a cat's ears swivel and they move toward the source. It's a hardwired response, not learned behavior. I spent about six months testing this on different cats, mostly strays around my apartment building. Some responded instantly. Others completely ignored it. A few seemed genuinely annoyed. The variation comes down to individual hearing sensitivity, past experience with the sound, and whether the cat actually has any reason to believe there's food nearby.
The Mysterious Pspsps Sound Explained Cracking The Internets Most Viral Audio Phenomenon
The viral audio that's been looping everywhere recently is just a human recording of that tongue-click technique. It spread because it's bizarrely effective at getting a visual reaction from cats on camera. You press your lips together, build air pressure behind them, then release while flicking your tongue upward against the hard palate. The result is a rapid series of clicks, usually sounding like "pss-pss-pss" or just "pspsps" depending on your mouth shape. It's the same sound most pet owners have been making unintentionally for decades, but now it's been stripped down, looped, and turned into an audio trend. Here's what actually happens when you try to replicate it yourself. Your tongue should rest lightly against the ridge behind your upper front teeth. Push your lips into a slight pucker but don't seal them completely tight. Blow steady air through the gap while flicking your tongue upward quickly, like you're trying to say the letter "T" repeatedly but with air instead of voice. The trick is not vocalizing at all. This needs to be purely breath noise. If you add any hum or tonal quality, it stops working on cats because the frequency profile changes completely. One thing nobody mentions is that the speed of the clicks matters more than the volume. Try around four to six clicks per second. Faster than that and it starts sounding like a motor, which actually spooks some cats. Slower and it doesn't register as prey-like movement. I found this by accident when one of the neighborhood cats kept walking away from rapid clicking but came running when I slowed down to a more measured pace.
There's also a version of this sound that uses the side of the mouth instead of the front. Some people press their tongue against their cheek and blow air sideways, creating a wetter, more guttural pspsps variant. This one seems to work better on older cats whose hearing has degraded in the higher frequencies. The lower-pitched version carries further into that diminished range. I switched to the cheek version when the elderly tabby at the end of my street stopped responding to the standard technique around age twelve. If you want the raw audio file that's been circulating, there are free samplers available on sites like Freesound.org and the Internet Archive's audio section. Search for "pspsps cat" and you'll find several clean recordings. I usually grab the one from user "whiskersaudio" because it has minimal background noise and sits around 440 Hz at the fundamental frequency, which aligns well with feline hearing sweet spots. The file is typically under 15 seconds and loops seamlessly. Don't expect this to work everywhere or on every cat. Kittens under four months old often haven't developed the full hearing range yet and won't respond. Cats with hearing loss from age or illness obviously won't react. And cats that live entirely indoors without any outdoor exposure sometimes treat the sound as unfamiliar noise rather than a lure. I had a Siamese that hissed at the sound for the first three weeks before eventually figuring out it meant nothing threatening and ignoring it completely.

The sound also attracts wildlife beyond cats. Squirrels, raccoons, and even foxes will sometimes investigate. That's not a bug, it's just that the frequency range overlaps with what several small mammals use for communication. If you're trying to use this near a garden or porch, be prepared for unexpected visitors. There's no real downside to making the sound yourself unless you live with other people who find it annoying, which is basically everyone. The recording versions are slightly more controlled in frequency, but the difference is marginal. A decent phone recording in a quiet room will capture the same basic pattern. I've compared phone recordings to professional captures and the feline response rate was identical across both.
How To Make The Sound Right Now
Stand in front of a mirror so you can watch your mouth. That helps because you can't feel what your tongue is doing from the inside. Practice the tongue flick separately first without any air, just the motion. Once that feels natural, add the breath. Start slow, maybe two clicks per second, then build up speed. The sound should come from the front of your mouth, not your throat. If your throat vibrates, you're doing it wrong and just making a raspy cough noise that cats will ignore. Recording quality matters if you plan to share or upload. A cheap phone mic will capture the clicks but also picks up lip smacks and breath noise that muddy the signal. A USB condenser mic placed about eight inches away works better. Don't get closer than six inches or the plosive air will overwhelm the capsule and you'll need to filter it out afterward. Even a basic free tool like Audacity will let you cut the low-end rumble below 200 Hz and boost the 2-5 kHz range where the actual click frequencies live. That frequency boost is important. Most people record this and it sounds flat or muffled on playback because phone microphones roll off the high end. The clicks sit in that 3-4 kHz range and if your recording equipment isn't capturing it, the cat hears something completely different than what you intended. I learned this the hard way after spending two weeks wondering why a cat wouldn't respond to my recording only to realize the file had been compressed so heavily in transit that the upper frequencies were gone.
The whole thing takes about five minutes to learn properly. The first time you try it, you'll probably spit a little. Everyone does. After ten or fifteen attempts, it becomes automatic. The muscle memory is straightforward, similar to learning to whistle with your fingers, except you don't need any tools. There's no app that does this better than your own mouth. Some apps claim to generate cat-lure frequencies digitally, but they're just playing back synthetic versions of the same sound at a fixed tempo. A real human variation has subtle timing differences between clicks that synthetic loops can't replicate, and cats seem to notice the difference. They respond to the organic version more consistently.
