Cats are weird. One minute they’re sleeping in a literal sunbeam for six hours, and the next, they’re sprinting across the house because a piece of dust caught the light. It’s that predatory drive—the "seek and destroy" instinct—that makes videos for cats to watch fish such a massive phenomenon on YouTube and TikTok.
You’ve probably seen the videos. A tablet perched on a sofa, a ginger tabby batting at a digital koi pond, and a million views in the corner. But is this actually good for them? Or are we just digital babysitting our pets because we’re too tired to wave a feather wand?
Honestly, it’s a bit of both.

The Science of the "Cat TV" Obsession
Cats don't see screens the way we do. Humans have a flicker fusion frequency—the speed at which images flash to look like smooth motion—of about 50 to 60 hertz. Cats? They need closer to 70 or 80 hertz. Older television sets used to look like a flickering mess to them, sort of like a broken fluorescent bulb. But modern LED and OLED screens, with their high refresh rates, have changed the game. Now, when you play videos for cats to watch fish, they’re seeing smooth, high-definition movement that mimics the real-life jitter of a goldfish or a tetra.
It’s about "enrichment." Indoor cats often suffer from a lack of environmental stimulation. When a cat stares at a screen, their brain is processing visual data that triggers their hunting sequence: stare, crouch, wiggle, pounce.
Dr. Sarah Ellis, a feline behavior specialist and co-author of The Trainable Cat, often discusses how mental stimulation is just as vital as physical exercise. Without it, cats get bored. And bored cats shred curtains.
Why Fish Specifically?
You’d think birds would be the top choice, but fish offer something unique: predictable but erratic movement within a contained frame. In a video of a bird, the bird often flies off-screen, which can frustrate a cat. Fish in a tank stay in the "box." The shimmering scales, the bubbles, and the contrast of a bright orange goldfish against a blue background create high visual salivity.
Basically, it’s feline eye candy.
Common Mistakes When Using Videos for Cats to Watch Fish
Most people just prop up an iPad and walk away. That’s a mistake. You’ve got to think about the physical setup. If you’ve got a 15-pound Maine Coon leaping at a glass-screened MacBook, you’re asking for a very expensive trip to the Apple Store.
Safety first. Always.
- Secure the device. Use a heavy-duty stand or lean it against something that won't tip.
- Screen protectors are non-negotiable. Cat claws are made of keratin, which is softer than Gorilla Glass, but they can still scratch coatings or trap grit that ruins the display.
- Watch the volume. Cats have incredibly sensitive hearing. The sound of digital water "glugging" at full volume is probably terrifying, not relaxing. Keep it low or mute it entirely.
The biggest issue, though, is "predatory frustration." This is a real thing. Imagine playing a video game where you can never actually win. You just keep hitting a button and nothing happens. For a cat, "catching" a digital fish results in no physical sensation under their paws. No fur, no scales, no resistance.
Ethologists like Ingrid Johnson emphasize that if a cat can't complete the "kill component" of the hunting cycle, they can become agitated. They might start redirected aggression—basically, they get annoyed and swat at your ankles because they couldn't catch the virtual koi.
How to Do It Right
To make videos for cats to watch fish a healthy part of their day, you have to bridge the gap between the digital and the physical.
Don't just turn the video off when they're done. While the video is playing, or right as you end the session, toss a physical toy or a few high-value treats (like freeze-dried minnows) onto the floor. This "ends" the hunt. It gives the cat the win they’ve been working for.

I’ve seen people use specific YouTube channels like Paul Dinning or Cat Games TV. These are great because they often use long takes without jarring cuts. Constant jump cuts confuse cats. They want to track a single target.
Also, variety matters. If you show them the same three goldfish every day, they’ll eventually habituate to it. They’re smart. They’ll figure out it’s a "lie." Switch it up with deep-sea footage or even pond scenes with lily pads to keep the visual "prey" fresh.
The Screen Time Debate for Pets
Is it possible to give a cat too much screen time? Probably.
A cat's primary sense is actually smell, followed closely by hearing. A screen provides zero olfactory input. If your cat spends four hours a day staring at a tablet, they aren't interacting with their environment. They aren't grooming, they aren't scratching their posts, and they aren't bonding with you.
Use it as a tool, not a lifestyle. It’s perfect for when you’re on a long Zoom call or when it’s raining outside and the real birds are hiding. But it shouldn't replace interactive play. A laser pointer is actually worse than a video, by the way, because the laser moves at speeds that aren't "natural" and is even harder to "catch" than a screen image. At least with a video, the cat is reacting to a lifelike image.
Is Your Cat Not Interested?
Don't be offended if your cat looks at the screen and then walks away to lick their butt. Some cats have a higher "prey drive" than others. Older cats or certain breeds might just find the whole thing beneath them.
My own cat, a rescue named Toast, couldn't care less about fish videos. But show him a video of a squirrel eating a nut? He’s practically inside the television. It’s all about individual preference.
Setting Up Your "Cat Cinema"
If you want to try this, start small. Put a 10-minute video on your phone and hold it for them. See if their ears swivel forward. See if their pupils dilate. Those are the signs of engagement.
If they start "chattering" (that weird ack-ack-ack noise they make at birds), you’ve hit the jackpot. That’s a high-arousal predatory response.
Actionable Steps for Success
To get the most out of using videos for cats to watch fish, follow this specific workflow to ensure your cat stays happy and your tech stays intact.
- Test the Refresh Rate: Ensure you are using a modern device (tablet or smart TV) produced within the last 5-7 years to ensure the frame rate is high enough for feline vision.
- The 15-Minute Rule: Limit sessions to 15 minutes. This prevents overstimulation and eye strain.
- The Physical Payoff: Always have a "finishing toy" ready. When the video ends, immediately initiate 2 minutes of play with a wand toy or kickaroo.
- Brightness Settings: Turn the brightness up slightly higher than you would for yourself, as cats have a tapetum lucidum (the reflective layer in their eyes) that handles light differently, but avoid blue-light filters which might dull the contrast of the fish.
- Check for Stress: If your cat starts over-grooming, pacing, or tail-twitching aggressively after watching, stop the videos. Some cats find the "unreachable prey" too stressful for their temperament.
By treating digital fish as a "supplement" rather than a "meal," you provide a safe, engaging way for your indoor predator to exercise their brain without ruining your furniture.
