## Adult Preventive Care
- **Exercise Needs**: Moderate
- **Grooming**: Low
- **Annual Exam Focus**: Weight/BCS monitoring; Cardiac auscultation; Dental examination; Renal function screening
- **Routine Care**: Monitor for age-related weight gain/obesity, renal failure, and hyperthyroidism. Regular cardiac screening is essential due to HCM risk. Transition to senior diet with joint supplements.

## Health Predispositions
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Hypertrophic Cardiomyopathy | Adult | High | No | No |

| Dental Disease | Adult | High | No | No |
| Hypertrophic Cardiomyopathy (HCM) | Adult | High | Yes | Yes |

## Obesity Management
- **Risk Level**: Moderate
- **Ideal BCS**: 5/9
- **Visual Cues**: Ribs easily palpable with slight fat covering; visible waist from above; abdominal tuck visible from side.
- **Daily Activity Target**: 30 minutes
- **Caloric Formula**: {"daily_kcal_per_kg": 50, "RER_factor": 70, "activity_multiplier": 1.2}

## Breeding & Genetics
- **Litter Size**: 3–5
- **Dystocia Risk**: Low
- **CHIC Required Tests**: PKD1; ALX1

## 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
- **Comfort**: Self-grooming; Sleeping in the sun; Relaxing/loafing independently; Stretching
- **Stress/Displacement**: Over-eating/weight gain; Hiding; Tail thrashing; Flattened ears
- **Breed-Specific**: Independent but affectionate; Entertaining themselves with toys; Excellent mousing/hunting instinct; Tolerating being left alone

## Vocalization Baseline
- **Types**: Meow (soliciting/greeting); Purr (contentment); Trill/Murmur (friendly approach); Chatter (hunting/prey desire)
- **Frequency Range**: 400-600
- **Tendency**: Moderate
- **Primary Modality**: Balanced Vocal/Body
- **Tail Signals**: Tail up = friendly greeting; Ears forward = curious/playful; Flattened ears = defensive/stressed; Tail thrashing = agitated

## Emotional Wellbeing
- **Anxiety Proneness**: Low
- **Top Triggers**: Lack of stimulation/boredom; Environmental changes; Unfamiliar pets/strangers
- **Separation Anxiety Risk**: Low
- **Calming Interventions**: Interactive play sessions; Vertical spaces/cat trees; Routine consistency; Puzzle feeders
- **Cognitive Dysfunction Risk**: Moderate

## Behavior Problems (Six-Etiology Classification)
- **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)

## 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
