Behavioral Ethogram

Locomotion	Clambering up and down cat trees; Batting around toys; Stalking/hunting movements; Pouncing
Social	Cuddling with owners; Bringing toys to owners; Interacting well with children and other pets; Greeting with trills/murmurs

Frequency Range	400-600
Tendency	Moderate
Primary Modality	Balanced Vocal/Body
Tail/Body Signals	Tail up = friendly greeting; Ears forward = curious/playful; Flattened ears = defensive/stressed; Tail thrashing = agitated

Behavior Problems

Top Problems	Play aggression; Destructive scratching; Overeating and food-seeking behavior; Attention-seeking vocalization
Medical Etiology	House soiling (FLUTD/urinary tract infections); Lethargy (obesity/hypertrophic cardiomyopathy); Sudden aggression (dental disease/arthritis)
Fear/Anxiety Etiology	Hiding behavior (loud noises/strangers); Inter-cat aggression (territorial insecurity); Over-grooming (environmental stress)
Frustration Etiology	Destructive scratching (lack of appropriate outlets); Play aggression (under-stimulation/lack of hunting outlets); Excessive vocalization (boredom)
Learned Behavior	Demand meowing for food; Waking owners at night for attention; Counter surfing for food
Cognitive Dysfunction	Nighttime vocalization; Spatial disorientation; Altered interactions with family members; Loss of litter box training

AI Communication Decoding

AI-Trainable Signals	Ear orientation (forward vs flattened); Tail movement (relaxed vs rapid swishing); Pupil dilation; Whisker position (relaxed vs pinned back); Body posture tension
Context-Dependent Vocalizations	Short meow at door = greeting vs short meow at bowl = food request; Purring while resting = contentment vs purring during vet exam = self-soothing/stress; Chirping at window = predatory excitement vs chirping at owner = play initiation
Interspecies Communication	Develops specific meow variations to communicate different needs to owners; Uses slow blinking and physical proximity to indicate trust; Frequently uses trills and chirps to initiate play or interaction
