Let's talk about a rabbit that feels like a living plush toy. The Californian Rex rabbit isn't just another cute face.

If you're considering one, or just got one, you're in the right place. This isn't a list of generic rabbit facts. This is a deep dive from someone who's made the mistakes so you don't have to. We'll cover what makes them tick, what they need to thrive, and the little things most care guides completely miss.

What Exactly Is a Californian Rex Rabbit?
First, a quick genetics lesson. The Californian Rex is a crossbreed, or a "designer rabbit" if you will. Breeders aimed to combine the iconic, dense, plush rex fur (a genetic mutation that makes guard hairs the same length as the undercoat) with the calm demeanor and striking Himalayan-style markings of the Californian rabbit. The result? A medium to large rabbit, typically weighing 7 to 10.5 pounds, with a velvety coat that comes in the classic Californian pattern: a white body with dark points (ears, nose, feet, and tail) in black, blue, chocolate, or lilac.
The rex fur is the star. It's dense, short (about 5/8 inch), and stands upright, giving it that incredible velvet texture. It's also less likely to shed clumps into the air compared to other coats, which is a big plus for mild allergy sufferers—though no rabbit is truly hypoallergenic.
The Non-Negotiable Californian Rex Care Checklist
Owning a Californian Rex isn't hard, but it's specific. Here’s the baseline setup you need to get right from day one.
Housing: Think Big, Even Bigger
These are not cage rabbits. A standard pet store cage is a prison for a rabbit this size. They need space to run, hop (a proper rabbit hop is three to four times their body length), and stand up on their hind legs without their ears touching the top.
Minimum Enclosure Size: A pen or an exercise pen (x-pen) is ideal. Aim for at least 12 square feet of continuous space, plus several hours of supervised free-roam time in a rabbit-proofed room daily. My first Rex, Mochi, lived in a penned area of 4ft x 6ft, and it was the difference between a content bunny and a frustrated one.
Flooring: Their feet are delicate. Rex rabbits, in particular, have slightly less fur padding on their hocks. Wire floors are an absolute no. Use soft, absorbent bedding like aspen shavings, paper-based bedding, or washable fleece liners over a solid floor.
Enrichment: Boredom is the Enemy
A bored rabbit is a destructive rabbit. Their teeth never stop growing, so they need to chew.
- Chew Toys: Applewood sticks, willow balls, and cardboard tunnels (like those from Rabbit Hole Hay) are lifesavers.
- Digging Box: Fill a shallow cardboard box with shredded paper or child-safe play sand. It satisfies a deep instinct.
- Foraging: Hide their daily pellets or leafy greens in a puzzle feeder or scatter them in their hay.
Diet Deep Dive: More Than Just Pellets and Hay
This is where most new owners slip up. The diet is 80% of your rabbit's health.
| Food Type | Daily Amount & Details | Brand/Type Notes |
|---|---|---|
| Unlimited Timothy Hay (or Orchard/Oat Hay) | Should make up 80-90% of diet. A pile bigger than the rabbit itself. | Fresh, sweet-smelling, not dusty. Oxbow or Small Pet Select are reliable. Avoid alfalfa hay for adults. |
| High-Quality Pellets | 1/4 cup per 5 lbs of body weight. Measure it! | Timothy-based, no colorful bits or seeds. Look for >18% fiber, |
| Fresh Leafy Greens | About 1 packed cup per 2 lbs body weight, split into 2 servings. | Romaine, green leaf lettuce, cilantro, parsley, dandelion greens, bok choy. Rotate varieties. |
| Treats & Veggies | Sparingly. A 1-inch cube of carrot or apple 2-3 times a week max. | Fruits and starchy veggies (carrot, banana) are high in sugar. Use for bonding/training only. |
| Water | Unlimited, fresh daily. Check consumption. | Heavy ceramic bowl is best. Also offer a water bottle as backup. |
The biggest mistake I see? Overfeeding pellets. It's tempting because they love them, but it leads to obesity and makes them ignore their hay, which is crucial for dental and gut health. A fat rabbit is an unhealthy rabbit, and their joints suffer.
Health Watch: Common Issues and Early Signs
Rex rabbits are generally hardy, but they have some breed-specific susceptibilities. Being proactive is everything.
Gastrointestinal (GI) Stasis: The rabbit owner's nightmare. It's when the gut slows down or stops. Signs: Small, misshapen poops or no poops, lethargy, hunched posture, grinding teeth (in pain). This is an emergency. Have a rabbit-savvy vet's number saved. Prevention is key: unlimited hay, low stress, and knowing their normal poop size and frequency.
Pododermatitis (Sore Hocks): Due to their slightly thinner fur padding. Look for redness, hair loss, or sores on the bottom of their back feet. Prevention: Soft flooring everywhere, keeping their weight healthy, and regular foot checks.
Dental Issues: All rabbits are prone to overgrown teeth if they don't chew enough hay. Signs: Drooling, wet chin, dropping food, weight loss. Yearly vet check-ups should include a peek at the molars.
Find a Vet Before You Need One: Not all vets see "exotics." Use the House Rabbit Society vet listing or local rabbit rescue recommendations to find one experienced with rabbits.
Grooming Secrets for That Signature Rex Coat
Here's a non-consensus opinion: you should rarely bathe a Californian Rex. Their dense coat holds moisture against the skin, leading to fungal infections. Spot clean with a damp cloth if needed.
The rex coat doesn't mat easily, but it sheds. During shedding seasons (spring/fall), you'll be amazed at the fur. Use a fine-toothed flea comb or a rubber grooming mitt like the ZoomGroom. Brush in the direction of hair growth, gently. Do this 2-3 times a week normally, daily when shedding.
The Ears: Check weekly. Rex rabbits can have slightly waxier ears. Use a cotton ball dampened with a rabbit-safe ear cleaner (ask your vet) to wipe the outer ear. Never stick anything into the ear canal.
Personality and Bonding: Getting to Know Your Bunny
Expect a generally calm, docile rabbit. They often have a lower "flight" instinct than some breeds, making them seem more confident. Many are "floor potatoes"—happy to lounge near you. But they're not devoid of personality. Mine would do "binkies" (joyful jumps and twists) at 7 AM every morning and nudge my foot for treats.
Bonding Tips: Sit on the floor during their free-roam time. Let them come to you. Offer a small piece of green from your hand. Talk softly. Avoid looming over them or picking them up unnecessarily—most rabbits hate it. Pet them on the head and cheeks, not the back or belly initially. Trust is earned daily.
They can be litter-trained! Use a large litter box with a paper-based litter (like Yesterday's News), and put a pile of hay in one end. They like to eat and poop at the same time. Clean it daily.
Your Questions, Answered (By Experience)
Are Californian Rex rabbits good with young children?
They can be, due to their typically calm nature, but never unsupervised. Teach children to sit on the floor to interact, pet gently, and never chase the rabbit. The rabbit must always have a safe, child-free retreat. A startled rabbit can scratch or bite. It's less about the rabbit's temperament and more about teaching respectful interaction.
My Californian Rex seems to drink less water than I expected. Is this normal?
Possibly. If they are eating a lot of fresh, watery greens (like romaine lettuce), their water intake from a bowl might decrease. However, you must monitor this closely. A sudden drop in drinking, especially with reduced eating, is a red flag for GI stasis. Ensure water is always fresh and offered in both a bowl and a bottle to see their preference. If in doubt, a vet check can rule out dental pain making drinking difficult.
What's the one piece of advice you wish you knew before getting your first Rex?
Budget for pet insurance or start an emergency vet fund immediately. A single GI stasis episode with overnight care can cost over $1,000. The second thing is to buy the largest pen you can possibly fit in your home from the start. You'll upgrade anyway, so save the money and stress. Their environment is the foundation of their health and happiness.
Bringing a Californian Rex rabbit into your home is committing to a unique and rewarding relationship. It's not just about providing shelter and food; it's about understanding a creature with specific needs and a subtle language of its own. Get the basics right—the massive space, the mountain of hay, the right vet—and you'll be rewarded with years of velvety companionship. Do your homework, be patient, and enjoy the process of getting to know one of the most tactilely wonderful pets out there.
