What Is the IQ of a Cat? Cat Smarts vs Humans and Dogs
What is the IQ of a cat? Cats don't have a real IQ score. IQ tests are designed for humans, and there's no valid way to turn cat behavior into a number. The closest comparison you'll see is that an adult cat's problem solving is somewhat like a human toddler's, but cats are famously hard to test, so lab results probably undersell them.
Honestly, humans are hard to "score" too, and most of us have no idea where our own reasoning drops off. IQ Tester shows you: Find my weak spots.
The IQ of a cat: short answer
Here's the no-fluff answer to "what is the average IQ of a cat":
- Real IQ number? None. Any "cat IQ 50" or "cat IQ 90" claim is invented.
- Human equivalent? People often compare cats to toddlers of around 2 to 3 years old, but that's a rough analogy, not a study result.
- Brain power? A 2017 study counting neurons in carnivore brains found house cats have around 250 million neurons in the cortex, about half what dogs have. Humans have roughly 16 billion.
- Best at? Hunting, spatial memory, independent problem solving and training you to feed them at 5 a.m.
So what is the IQ of a house cat equivalent to? A tiny, fluffy, stubborn specialist.
Why cats are hard to test
This is the thing most pet sites skip. When researchers compare dogs and cats, cats often look "dumber." But a big part of that is about cooperation, not ability.
Cats don't do tasks for approval
Dogs have been bred for thousands of years to work with humans. They look to you, follow your pointing and try hard to please. Cats are more like: "I heard you. I'm choosing not to."
Lab settings stress cats out
Cats are territorial. Put them in a strange room with strange people and many will hide, freeze or just leave. That gives you a result, but it isn't a measure of intelligence.
Many cat studies now happen at home
Because of this, researchers increasingly test cats in their own homes or cafés. When the setting is chill, cats show off a lot more.
The takeaway: "What is the estimated IQ of a cat" is partly a question about how good our tests are, not just how smart cats are. (Same energy as a smart student bombing a test because they were anxious.)
What cats are smart at
They know their names
Japanese researchers (Atsuko Saito and colleagues, 2019) found that pet cats can tell their own name apart from other similar-sounding words. Whether they come when called is... a separate issue.
They recognize your voice
Earlier research from the same team found cats react differently to their owner's voice than to a stranger's, even if they don't get up.
Object permanence
Cats understand that an object still exists when it's hidden. That's a skill human babies develop in their first year or two, and it's key for hunting.
Spatial memory and hunting logic
Cats track moving prey, predict where it'll go and remember routes around their territory. That's real-time pattern recognition.
Training humans
Adult cats rarely meow at each other, yet plenty of them meow at their humans all day. Many cat owners notice their cat uses different meows for food, doors and attention. That's a form of social learning: figuring out what works on you.
Cat vs dog: who's smarter?
The classic "iq of a dog vs cat" fight.
| Skill | Cats | Dogs |
|---|---|---|
| Cortical neurons (2017 study) | ~250 million | ~530 million |
| Reading human gestures | Can do it, often won't | Elite |
| Independent problem solving | Strong | Good |
| Learning commands | Possible with patience | Easy for many breeds |
| Cooperating with researchers | Low | High |
| Hunting and stealth | Elite | Varies by breed |
Verdict: dogs probably win on raw processing power and teamwork. Cats win on independence and self-reliance. It's like comparing the group-project hero with the person who does everything solo at 2 a.m. and still passes.

Cat brain facts that surprise people
- Cat and human brains share structures. Both have a cerebral cortex with similar regions for things like vision and movement, just at a much smaller scale.
- Brain size isn't everything. Crows have tiny brains and still make tools. Check the average IQ of a crow for that plot twist.
- Cats sleep a lot. Often 12 to 16 hours a day. Honestly, iconic.
- The slow blink is real. A 2020 study found cats were more likely to approach a stranger who slow-blinked at them, which suggests slow blinks are a friendly signal.
Smartest cat breeds?
You'll see lists naming Siamese, Abyssinian, Bengal and others as the "smartest." These usually reflect how active, curious or trainable a breed seems, not formal testing. Individual personality matters way more than breed.
What an "IQ" comparison can and can't tell you
"What is the IQ of a cat compared to a human" feels like a simple question. It isn't, because:
- Different species, different jobs. Cats evolved to hunt alone. Humans evolved to talk, plan and build.
- Tests reward the test-maker's strengths. Human IQ tests use words, numbers and abstract patterns.
- Cooperation changes scores. If the subject won't try, you're measuring motivation.
Point 3 applies to you too. If you've ever done a practice test half-heartedly, rushed it or got distracted by your phone, your result said more about your mood than your mind. And on your own, it's genuinely hard to know which skill you're weak at versus which one you just didn't try on.
IQ Tester is designed around that: 20 untimed questions, so you're not rushed, and if you close the tab your answers are saved. Your result shows your score band and category strengths across number series, verbal, logic and patterns, and the guides pick out a weak spot and a short daily drill. Find my weak spots

FAQ
What is the IQ of a cat compared to a human?
There's no real IQ score for cats, so there's no direct number to compare. People often describe cat problem solving as roughly toddler-like, but that's a loose analogy, and cats are much better than toddlers at hunting and spatial tasks.
Are cats smarter than dogs?
Dogs have about twice as many cortical neurons and are better at cooperating with humans, so they usually do better in studies. Cats are strong independent problem solvers, and many don't cooperate with tests, which likely makes them look less smart than they are.
What is the iq age of a cat?
Some sources say cats think like a 2 to 3-year-old child. It's a rough comparison, not a measured result, and cats outperform toddlers at many skills.
Do cats know their names?
Research published in 2019 found pet cats can tell their own names apart from similar words. Whether they choose to respond is a different story.
How can I tell if my cat is smart?
Watch for problem solving, like opening doors or cupboards, learning routines, reacting to their name and figuring out how to get your attention. Puzzle feeders are a fun, safe way to see how your cat thinks.
