Welfare floor for a free-roam pet cat: a secure indoor home with one litter box per cat plus one extra (placed in different rooms), multiple scratching posts and a sturdy cat tree, food and water stations kept away from the litter, and 20–30 minutes of interactive wand/puzzle play every day. Outdoor access only via a fully-fenced catio or harness walks.
This is a large breed (5–10+ kg adult) — use an XL or oversized litter box, sturdy XL cat trees rated for the bodyweight, and feeding bowls/water fountains scaled accordingly.

Recommended
Multi-room home with vertical territory
≥ 2 floors / wide rooms, cat trees, catio access
A multi-cat-friendly household with several tall cat trees and wall-mounted perches, window seats with a view, separate feeding stations per cat to reduce resource guarding, and access to a screened catio or balcony for sun and air. Vertical territory matters as much as floor space for cats.
Large-breed cats need more floor area than the standard household provides — a multi-room run plus tall, sturdy climbing structure prevents weight gain and boredom-aggression.

Ideal
Indoor home + catio + enriched garden
House + outdoor catio + cat-proofed garden
Indoor home paired with a large outdoor catio (or a cat-proof-fenced garden), abundant environmental enrichment (climbing branches, foraging puzzles, water features), and group-compatible housing if multi-cat. This combines the safety of indoor-only living with the behavioural enrichment of supervised outdoor time.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Newborn
Newborn mammals are nursed on their mother's milk. Many are born helpless — blind, deaf, and sparsely furred (altricial, as in dogs, cats, and rodents) — while others stand and follow within hours (precocial, as in hoofed livestock).

Juvenile
After weaning, juveniles grow quickly and become increasingly active, playful, and independent. Adult coat, proportions, and (in many species) the permanent teeth come in as they approach full size.

Adult
Adults reach full body size and sexual maturity, with the species' mature coat and build. Sexual dimorphism — differences in size, mane, horns, or markings — is pronounced in some mammals and subtle in others.
Senior
Senior animals show aging signs such as graying fur, reduced activity, and a greater need for veterinary monitoring of joints, teeth, and organ function. Lifespan and the onset of old age vary widely by species and size.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Fully apartment- and house-friendly, but appreciates vertical space; sturdy cat trees and wide perches suit their size and weight. Highly playful and moderately active, they enjoy interactive play, puzzle feeders, and even leash walks. Provide a large litter box (oversized to fit their body) and scratching posts tall enough for a big cat to stretch fully.
Diet
Feed a complete, life-stage-appropriate diet; they mature slowly (full size by 3-4 years) so a quality kitten/growth food well into adolescence supports development. Prone to obesity if free-fed, which compounds joint and cardiac risk, so portion-control and monitor body condition. Ensure good hydration (wet food, water fountains) to support urinary and renal health.
Behavior & temperament
Friendly, affectionate, and people-oriented without being clingy; often described as dog-like, following owners room to room and tolerating handling. Intelligent and trainable, enjoying fetch, clicker tricks, and harness work. Chirps and trills rather than meows loudly. Excellent with children and other pets, including cat-friendly dogs. Moderate to high energy that mellows with age.
Health
Predisposed to hypertrophic cardiomyopathy (HCM) — a specific MYBPC3 mutation is common in the breed; DNA test breeding stock and screen with echocardiography. Also at risk for hip dysplasia (large frame), spinal muscular atrophy (SMA, DNA test available), polycystic kidney disease (PKD), and patellar luxation. Buy from breeders who screen for HCM, SMA, hip dysplasia, and PKD. Watch weight to protect joints and heart.
Tips, DIY & hacks
The semi-long, shaggy double coat is relatively low-matting but needs combing 2-3x weekly (more during seasonal shed) to prevent tangles behind the ears, in the ruff, and on the belly/breeches. Heavy seasonal shedders. Bathing is occasional. Trim claws, check ears, and brush teeth routinely. Their water-fascination and intelligence make fountains and puzzle toys big wins. Reward-based training works very well.
