Cats do not have a valid human-style IQ score

Feline intelligence is studied task by task, including memory, quantity discrimination, problem solving, and owner recognition. Explore what peer-reviewed research shows and where its limits remain.

Research notes for cat lovers

Understand the cats you love through peer-reviewed research

Studies suggest cats distinguish their own names, infer an unseen owner's location from voice, and use information from a single eating experience. We explain methods, sample sizes, and limitations without overstating the findings.

The science behind it

This test is designed on intelligence research—why abstract figures can measure IQ.

Strongly reflects the g factor

Raven's matrix reasoning is considered one of the tasks that best reflects the general intelligence g (Spearman 1904) common to many cognitive challenges, and it is known to have a high g loading.

Independent of language and culture

Because it uses only abstract figures, it is largely unaffected by language ability, educational background, or cultural knowledge, allowing fluid reasoning (Gf) to be measured in a pure form (CHC theory; McGrew 2009).

Rules are theoretically defined

Items are automatically generated based on the rules Carpenter et al. (1990) identified in the RPM (rotation, quantitative progression, addition and subtraction of figures, and distribution of three values). Each answer is uniquely determined.

Scored with item response theory (IRT)

Rather than counting correct answers, ability θ is estimated with an IRT model that adds a guessing floor c=1/6 for the 6-choice items (so lucky guesses are not mistaken for ability), so correctly answering harder items is weighted more heavily. The estimate is calibrated to a population of θ~N(0,1) and converted to IQ=100+15θ (deviation IQ, SD 15).

How to raise your IQ

1

Do brain-stimulating activities

Puzzles, problem-solving, and learning new skills strengthen neural connections.

2

Get quality sleep and rest

Sleep is essential for attention, memory, and decision-making. Adequate rest optimizes cognitive performance.

3

Eat a balanced diet

Antioxidants, omega-3s, vitamins, and minerals support brain health and cognitive function.

4

Exercise regularly

Exercise boosts blood flow to the brain, helps generate new brain cells, and improves cognition.

5

Keep learning

Reading, courses, and new experiences stimulate the brain and build adaptability. Consistent learning is key.

6

Manage stress and mental health

Chronic stress harms cognition. Meditation and mindfulness help keep your brain healthy.

Kenta

I could really focus with just figures. The detailed analysis—and the cats that helped me relax—was wonderful.

Misaki

Loved getting a certificate! Solving alongside cute cats made it even more fun to share.

Ryo

The difficulty ramp feels real. The cat photos gave me a calming break between questions.

Aya

It feels fair regardless of language. The kitten photos helped me stay relaxed and focused.

Quick—done in 10 minutes. The polished results page and fluffy cat at the end were perfect.

FAQ

Is this IQ test free?
Yes, taking the test is free. Full results cost ¥1,200, including a ¥1,000 donation to cat-protection organizations.
How long is it and how many questions?
20 questions. No time limit, but your speed factors into the score. All are abstract-figure pattern items (6 choices), independent of language or knowledge.
Is the displayed IQ accurate?
It's an estimate based on a normal model (mean 100, SD 15). It's a fun guide, not an official psychological assessment.
Do I need to sign up?
No. You can take it anonymously; sign in with Google to save results across devices.
What is NekoIQ (iq cat)? Does it measure my cat's IQ?
NekoIQ (iq cat) is a free IQ test for humans, guided by friendly cat characters — it doesn't measure feline intelligence. Figure-based items follow Raven's Progressive Matrices and are scored with Item Response Theory (IRT).
Can a cat's IQ be measured? I want to learn about feline intelligence
A human IQ scale cannot be applied to cats, so there is no valid feline IQ score. Human IQ is a relative value standardized to a mean of 100 and an SD of 15 within a human age group. Feline intelligence is instead studied task by task — name discrimination, tracking unseen locations, short-term memory. Our cat-cognition article series covers the peer-reviewed research.
