| Anxiety Proneness | Low |
|---|---|
| Top Triggers | Environmental changes/break from routine; Loud/sustained chaos; Persistent handling against their will; New pets/family members; Lack of personal space |
| Separation Anxiety Risk | Low |
| Calming Interventions | Routine consistency; Dedicated scratching posts; Interactive toys/food puzzles; Vertical spaces/quiet retreats; Regular exercise |
| Enrichment Needs | Moderate |
| Cognitive Dysfunction Risk | High |
| Sociability Score | 3/10 |
| Locomotion | Slow deliberate walking; Nimble climbing; Low-key surveying; Sitting upright and still; Graceful jumping |
|---|---|
| Social | Slow blinking; Sitting nearby; Nose touches; Gentle head tilts; Deep purring when petted |
| Comfort | Kneading; Stretching; Self-grooming; Curled up sleeping; Napping in shared spaces |
| Stress/Displacement | Excessive grooming; Hiding; Crouching low to the ground; Flattened ears; Fast agitated tail swishing |
| Breed-Specific | Observing from a distance; Following owner room-to-room without demanding attention; Low-key surveying of environment |
| Types | Short meow (greeting); Long drawn-out meow (demand); Purr (contentment/self-soothing); Hiss (fear/defensiveness) |
|---|---|
| Frequency Range | 400-600 |
| Tendency | Low |
| Primary Modality | Primarily Body Language |
| Tail/Body Signals | Upright tail = happiness/confidence; Tail twitching/swishing = excitement/irritation; Ears forward = alert/curious; Ears flattened = fearful/threatened |
| Top Problems | Handling aggression; Inappropriate elimination; Destructive scratching; Play aggression |
|---|---|
| Medical Etiology | Inappropriate elimination (FLUTD/urinary tract issues); Lethargy or reluctance to jump (Osteoarthritis/obesity); Sudden aggression (Pain from HCM or dental disease) |
| Fear/Anxiety Etiology | Hiding behavior (stranger anxiety); Inter-cat aggression (territorial anxiety); Avoidance behavior (fear of being restrained) |
| Frustration Etiology | Play aggression (under-stimulation); Destructive scratching (lack of appropriate outlets); Attention-seeking behaviors (boredom) |
| Learned Behavior | Demand meowing for food; Waking owners at night for attention; Swatting when petted too long |
| Cognitive Dysfunction | Nighttime vocalization; Disorientation in familiar spaces; Loss of litter box training; Altered sleep-wake cycles |
| AI-Trainable Signals | Ear position/rotation; Tail flicking/swishing; Pupil dilation; Whisker position; Body posture tension |
|---|---|
| Context-Dependent Vocalizations | Short trill upon waking = greeting vs short trill during play = excitement; Purring when petted = contentment vs purring at vet = stress/self-soothing; Soft meow at door = request vs soft meow near food bowl = hunger |
| Interspecies Communication | Uses slow blinking to indicate trust/relaxation; Relies heavily on subtle body language rather than vocalization; Often follows owners from room to room as a sign of affection rather than demanding attention |
