Mood Analysis

Based on peer-reviewed feline ethology & the Feline Action Coding System (CatFACS)

This advanced diagnostic engine is based on the Feline Facial Action Coding System (CatFACS) and the study of Feline Ethology, which are the objective standards for measuring feline muscle movement and social signaling.

The tool specifically analyzes:

  • The Orbital Region: Based on research from the University of Portsmouth regarding the “Slow Blink” and eye closure as affiliative signals.
  • Ear Pinnae Orientation: Utilizing data on how ear rotation correlates with autonomic nervous system arousal (fear vs. aggression).
  • Pupillary Response: Factoring in Mydriasis (dilation) as a clinical indicator of sympathetic activation, often seen in predatory or high-stress states.


This Behavioral Diagnostic Engine is based on the Feline Facial Action Coding System (CatFACS) and peer-reviewed ethological studies from the University of Portsmouth and the University of Lincoln, providing a standardized framework for interpreting feline micro-expressions and autonomic responses.
