Hay first: the Californian's everyday foundation
A Californian rabbit's main everyday diet is grass hay — timothy, orchard grass, or a similar grass hay available at all hours, in a pile at least the size of the rabbit itself. Californians are a large, well-muscled breed, and everything else in the bowl is a supplement to the hay rather than a rival to it. If you picture the day's eating as a whole, hay should account for the great majority of it, with pellets and greens as the measured edges around that forage core.
Why grass hay, not richer forage, suits an adult Californian
Adult Californian rabbits do not need the calcium and protein density of legume hay such as alfalfa, which suits growing youngsters and nursing mothers instead. Grass hay's long, coarse strands demand extended sideways chewing, wearing the back teeth evenly, and its fiber keeps a big rabbit's gut moving through the hair swallowed during grooming. A Californian that turns picky between hay types usually settles when one grass hay is offered consistently and refreshed daily so it smells fresh.
Pellets and greens around the hay core
Plain, hay-based pellets belong in a measured portion — around a quarter cup per five pounds of body weight — never in a self-serve hopper a food-motivated Californian can graze from. The greens bowl is where generosity belongs: two or more packed cups of leafy greens daily, built from romaine, kale, herbs, and dandelion, introducing each new green gradually over several days. Wash greens, serve them fresh, and remove wilted leftovers so the hay, not the salad bar, stays the pen's constant.
Water, bowls, and the large-rabbit practicalities
A Californian rabbit drinks a lot by small-pet standards, and many drink more willingly from a heavy ceramic bowl than a bottle, though a bowl needs rinsing daily because big rabbits backwash hay dust into it. Place the hay rack where the rabbit can eat while sitting in its litter area, since rabbits naturally graze and pass droppings in the same spot. A sturdy rack matters at this size — a Californian leaning its full weight on a flimsy feeder will bend or break it.
Young Californians are the alfalfa exception
The grass-hay rule applies to adult Californian rabbits; youngsters under about seven months, and mothers nursing a litter, genuinely do better with alfalfa hay and more generous pellets while they are building that large frame. The changeover matters more than the date: move a young Californian onto grass hay gradually across a couple of weeks, mixing the two hays in shifting proportions, so the gut adjusts and the rabbit does not stage a hunger strike against the plainer forage it will eat for the rest of its life.
Keeping the hay-first diet honest
The most common way a Californian's diet drifts is pellet creep: the hay stays available but extra scoops appear, and the rabbit sensibly eats the richer food first and the hay second. Weigh monthly, feel for ribs under a light covering, and treat soft uneaten cecotropes as a sign the extras have grown too rich. A Californian that refuses hay entirely or stops producing droppings needs a veterinarian the same day.
