A large American heritage meat-and-fur breed developed in California around 1917, distinctive for its deep mandolin (semi-arch) silhouette. Once one of the most popular commercial rabbits, it is now critically rare and prized for fine fur and gentle temperament.

From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Hutch + daily exercise run
Hutch 12 sq ft + 32 sq ft exercise run
Welfare floor: a rabbit must be able to take 3–4 consecutive hops, stand fully upright on its hind legs, and stretch flat. A hutch alone is never enough — pair it with several hours of daily run access. The American is a medium 4–5 kg breed; standard welfare floor applies.

Recommended
X-pen with free-roam access
X-pen ~16 sq ft, free-roam most of the day
Exercise pen or rabbit-proofed room available most of the day, with hides at both ends, a hay station, dig/forage boxes, and a litter tray. Bonded pairs need proportionally more space.

Ideal
Free-roam house rabbit
Full room / free-roam, 24/7 access
Free-roam (like a house cat) with rabbit-proofed cabling, multiple hides, dig boxes, levels, and constant access to hay, water, and a litter area. Best welfare outcome and most natural behaviour.
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.
House in a roomy hutch or wire cage sized for a large breed (minimum about 30 x 36 in / 76 x 91 cm floor, taller is better), with a solid resting board to prevent sore hocks on wire. Provide a sheltered, well-ventilated, predator-proof space out of direct sun and draughts; rabbits tolerate cold far better than heat and suffer above ~28 C/82 F. A secure run or exercise pen for daily out-of-cage time supports musculoskeletal health in this big-bodied breed.
Diet
Base the diet on unlimited grass hay (timothy, orchard, meadow) for gut and dental health, supplemented with a measured portion of quality grass-based pellet and a daily handful of safe leafy greens. Provide constant fresh water. Limit high-calorie treats and cap pellets in adults to prevent obesity, which this large breed is prone to. Introduce greens gradually to avoid digestive upset.
Behavior & temperament
A docile, calm, easy-handled breed with a reputation as one of the most even-tempered large rabbits; does are notably good, attentive mothers. Historically a dual-purpose meat-and-fur rabbit and still raised for the homestead table and its dense, fine pelt, but its gentle nature also makes it a good pet and show animal. Like all rabbits it is a social prey animal that does best with companionship and gentle, predictable handling.
Health
Susceptible to the usual rabbit concerns: GI stasis (any reduction in eating or droppings is an emergency), dental malocclusion, and heat stress. The large frame predisposes to sore hocks (pododermatitis) on wire floors and to obesity if overfed. Unspayed does have a high lifetime risk of uterine cancer, so spaying is advised for pets. Keep current on parasite control and watch for the RHDV2 virus where present (vaccination available in some regions).
Tips, DIY & hacks
Provide a solid resting mat or board in wire cages to protect the hocks of this heavy breed. The flyback fur needs little grooming—weekly brushing, more during a moult—and should not be over-bathed. Support the hindquarters fully when lifting; never let a large rabbit dangle. As a rare heritage breed, source from breeders working with the American Livestock/Rabbit Breeders Association conservation efforts and consider keeping breeding stock to help recover numbers.
