Of all the pet trends that have gone viral over the past few years, the "cat slow blink challenge" stands out for a good reason: it's actually backed by real research, not just internet charm. If you haven't tried it yet, here's the science behind it and exactly how to do it right.
What Is the Slow Blink, Exactly?
A slow blink is a deliberate, unhurried closing and reopening of the eyes, often accompanied by a relaxed facial expression — distinct from a normal, quick blink or an alert, wide-eyed stare. Cats use it toward humans and other cats they trust and feel comfortable around.
The Research Behind It
A study published in the journal Scientific Reports found that cats were more likely to approach a stranger after that person slow-blinked at them, and cats themselves slow-blink more in response to their owner's slow blink compared to a neutral expression. This provides genuine scientific support for what cat owners have long suspected — it really is a trust and affection signal, sometimes informally called a "cat kiss."
How to Try It Yourself
Make relaxed eye contact with your cat from a comfortable distance, then slowly close your eyes for a second or two before slowly reopening them. Avoid a hard, sustained stare beforehand, since direct staring can actually read as a threat to cats — the key is a soft, relaxed approach throughout.
What Counts as a Response
A cat slow-blinking back, a relaxed slow eye squint, or approaching you afterward are all considered positive responses. Not every cat will reciprocate immediately, especially shyer or less bonded cats — like any trust-building signal, it often works best as part of a consistent, patient practice rather than a one-time test.
Why This Matters Beyond the Trend
Beyond being a fun bonding ritual, understanding and using feline communication signals like this can genuinely help build trust with a nervous or newly adopted cat. It's a low-pressure way to communicate calm intentions without physical contact, which matters a lot for cats who aren't ready for touch yet.
Pairing It With Other Trust-Building Habits
The slow blink works even better as part of a broader pattern of calm, predictable interaction — consistent gentle handling, respecting a cat's space, and positive interactive play all reinforce the same message of safety and trust. Regular, engaging play sessions build that same foundation of comfort. Our Feather Teaser Wand is a great tool for building trust through positive, low-pressure play alongside slow-blink practice.
Give Them a Comfortable Space to Practice In
Cats are most likely to engage in relaxed communication like the slow blink when they already feel secure in their environment. A cozy, familiar resting spot helps set the stage for these calm, trust-building moments. Our Cozy Pet Nest Mat gives your cat that comfortable baseline of security.
The Takeaway
The cat slow blink is one of the rare viral trends that's genuinely grounded in real behavioral science — a simple, gentle way to communicate trust and affection in a language your cat actually understands. Try it consistently, especially with a shy or newly adopted cat, and watch for the moment they blink back.
