Food for seven days: hay by the bag, pellets by the scoop
A Californian is a large breed, white-bodied with dark points on the nose, ears, feet, and tail, and it eats like one. Pack hay generously for the full week, a big rabbit works through roughly its own body size in hay daily, and running out on day five leaves your sitter hunting for a suitable bale. Send the hay your rabbit already eats, in the bag or box it knows, rather than a new brand bought for the trip. Pellets should travel pre-measured or with the exact scoop and a written daily amount, and the greens plan should be a list, not a bag: leafy greens spoil, so write what to buy, how much per day, and which greens your Californian already tolerates.
Litter, bedding, and the tray setup
Pack the litter tray arrangement your rabbit uses at home, or clear instructions and supplies to recreate it: the tray itself if it travels, a week's worth of the same litter, and spare hay for the eating end of the tray. Rabbits are creatures of toilet habit, and a familiar-smelling tray in the same corner of the pen settles a large rabbit faster than any toy. Add a fleece or blanket that smells of home for the sleeping area, plus a spare, because a week is long enough for one to need washing. Paper or card for lining the pen floor is worth including if your sitter's flooring is slippery, since a heavy rabbit that cannot grip will splay and panic when it tries to move quickly.
Space and exercise gear for a big rabbit
A Californian cannot spend a week in a hutch-sized box, so pack the means of giving it room. Folding pen panels that clip together are the practical choice: they travel flat, set up in the sitter's room, and give a large rabbit space to stretch, periscope, and move between the tray and its blanket. Include the water setup your rabbit uses, a heavy crock bowl is often better than a bottle for a big drinker, plus a spare. Chewing supplies are equipment, not extras: willow sticks, cardboard tubes, and wooden toys sized for a strong rabbit jaw, enough for the week, because a bored Californian will redirect that chewing onto the sitter's skirting boards and furniture legs.
The carrier and the journey kit
Your Californian needs a carrier rated for its weight, lined with hay and a non-slip base, and large enough for the rabbit to lie stretched rather than sit hunched. Pack the carrier as part of the sitter kit even if the sitter never moves the rabbit, because a vet trip mid-week is exactly when a proper carrier is needed and a cardboard box will fail under a heavy, frightened rabbit. Add a small journey pouch: a handful of the usual greens for arrival, a bottle of water from home for the first refill, and a towel for safe handling. Nothing in the kit should be new to the rabbit on travel day.
Paperwork, vet details, and the gut warning
The last things into the bag are the written routine and the emergency sheet. For a Californian, the sitter needs feeding times, the pen routine, handling guidance that stresses supporting the hindquarters of a heavy rabbit with both arms, and the warning signs that cannot wait: not eating, few droppings, hunched tooth-grinding, or lethargy on a hot day, since large rabbits overheat quickly. Include your vet's number, your own, and written permission to seek treatment. Tucking that sheet into KinsLe's Care Pass alongside the packing list means your sitter can confirm the hay supply, the litter spares, and the vet's number all match the plan before your first day away is over.
