CAEN Inc. (Headquarters: Shibuya, Tokyo; CEO: Shogo Omori) has released "Cat 16 Types Personality Test (CATS)", a unique web service that classifies cat personalities into 16 types, for web browsers today, February 22, 2025 — Cat Day.
■ What is "Cat 16 Types Personality Test (CATS)"?
"Cat 16 Types Personality Test (CATS)" is a 16-type personality test that adapts MBTI (Myers-Briggs Type Indicator) to the world of cats. Users simply answer 12 straightforward YES/NO questions to have their personality diagnosed as one of 16 cat types.
■ Psychological analysis using the original 4-indicator "C-A-T-S" framework
CATS classifies personality using the original 4-indicator "C-A-T-S" framework.
Each indicator represents a feline trait.
★ Cautiousness
Cautious (strong) ↔︎ Daring (weak)
★ Autonomy
Autonomous (low) ↔︎ Obliging (high)
★ Temperament
Temperate (low) ↔︎ Gushing (high)
★ Stability
Steady (low) ↔︎ Energetic (high)
■ Sample diagnosis results
For example, someone who is 'highly cautious, prefers solitude, rarely shows emotions on their face, and acts in a calm manner'
would be diagnosed as a "Russian Blue" — the "C-A-T-S" type where all indicators are cat-like.

For example, someone who is 'highly curious, cooperative, expressive with emotions, and actively energetic'
would be diagnosed as a "Japanese Bobtail" — the "D-O-G-E" type where all indicators lean toward the non-cat side.

■Message from CEO Omori
In time for Cat Day, I created CATS as something cat lovers can enjoy.
I hope this personality test — which views personality through the unique lens of "how cat-like are you?" — can spark deeper conversations.
Please try the CATS test even if you're not a cat lover yet, and let it welcome you into the world of cat enthusiasts!
