A heavy commercial meat breed developed in California in the 1920s by crossing Himalayan, Chinchilla, and New Zealand White rabbits. Recognizable as a white rabbit with Himalayan-pattern dark points and red eyes.

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. Californian is a medium-large 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.
Needs a large hutch or grow-out pen suited to a heavy rabbit, with solid resting areas (large rabbits are prone to sore hocks on wire). Provide bedding, shelter from heat and damp, and room to move. Commonly raised in sheltered outdoor hutches or barns; pet keepers should give generous floor space and daily exercise.
Diet
Unlimited grass hay plus a measured ration of quality pellets; growing or breeding stock are fed for steady growth and condition. Daily leafy greens for pets. Fresh water at all times. As a large, fast-growing breed, balanced feeding prevents both poor growth and obesity in pet animals.
Behavior & temperament
A meat (and show) breed, valued for a high dressing-out percentage, fine bone, and good meat-to-bone ratio. Temperament is generally calm, docile, and easy to handle, which also makes them steady pets. The dark points develop with age and can darken in cold weather (a temperature-sensitive Himalayan trait).
Health
Sore hocks (ulcerative pododermatitis) are the main breed-relevant concern because of their weight — provide solid flooring and good bedding. Otherwise hardy; standard care for dental health, GI stasis, obesity, and (in unspayed does) uterine disease. Red eyes mean no pigment, but this causes no special problem beyond mild light sensitivity.
Tips, DIY & hacks
For pets, prioritize soft, solid flooring and weight management to prevent sore hocks. Handle confidently and support the hindquarters when lifting a heavy rabbit. Spay/neuter pet animals for health and behavior. Note that the point color is heat/cold-sensitive, so coloration can shift seasonally — this is normal.
