What Is a Rex Rabbit?
Note: While the Standard Rex and Mini Rex share the same velvety fur, they are recognized as two distinct breeds by ARBA. This guide focuses specifically on the Standard Rex rabbit.
The Rex rabbit is a medium-sized domestic breed weighing 7 to 10 pounds, officially recognized by the American Rabbit Breeders Association (ARBA). It is uniquely defined by a natural genetic mutation that eliminates coarse guard hairs, leaving only the soft undercoat — giving its fur a dense, plush, velvety texture unlike any other rabbit breed. Rex rabbits are calm, intelligent, and highly social, making them one of the top recommended breeds for US families and first-time owners.
The History and Origin of the Rex Rabbit
The Rex rabbit’s story begins in a small French village in 1919, when a litter of wild gray rabbits was discovered carrying an unusual recessive genetic mutation. This mutation caused the guard hairs — the coarser, longer outer hairs that normally protect a rabbit’s undercoat — to grow shorter than the soft undercoat beneath them. The result was a coat that felt extraordinarily plush, like velvet.
French breeders recognized the commercial and aesthetic value of this mutation immediately. The breed was first exhibited publicly at the Paris International Rabbit Show in 1924, where it caused a sensation. Rex rabbits were imported to the United States the same year and quickly gained ARBA recognition. Throughout the early 20th century, their luxurious fur made them valuable in the fur trade. Today, they are cherished almost exclusively as pets and show rabbits across the US.
Standard Rex vs. Mini Rex: Which Is Right for You?
Many US buyers are surprised to learn there are two distinct ARBA-recognized Rex varieties. Choosing the right one matters:
| Feature | Standard Rex | Mini Rex |
| Weight | 7–10 lbs | 3–4.5 lbs |
| Lifespan | 5–8 years | 7–10 years |
| Size Category | Large/Medium | Small/Dwarf |
| Best For | Families, older children | Apartments, singles, seniors |
| Activity Level | Moderate | Moderate–High |
| ARBA Status | Recognized | Recognized |
| Fur Texture | Dense velvet | Dense velvet (slightly finer) |
| Handling | Sturdy, tolerates children | More delicate, careful handling needed |
Pro Tip: If you have young children or limited space, the Mini Rex is often the better choice for US apartment living. If you want a bigger, more laid-back companion, the Standard Rex is ideal.
Rex Rabbit Temperament and Personality
Rex rabbits are known for their friendly and relaxed nature. They enjoy human interaction and form strong bonds with their owners over time.
Personality Traits:
- Calm and gentle — rarely aggressive when handled correctly
- Curious and playful — enjoy exploring new toys and spaces
- Intelligent and food-motivated — respond well to treat-based training
- Social — thrive on daily interaction and dislike long periods of isolation
These rabbits make excellent family pets. Children should be taught gentle handling techniques — Rex rabbits, like all rabbits, have fragile spines and should never be dropped or squeezed.
Rex Rabbit Lifespan
| Type | Average Lifespan | With Excellent Care |
| Standard Rex | 5–8 years | Up to 10 years |
| Mini Rex | 7–10 years | Up to 12 years |
A healthy diet, clean living space, spay/neuter surgery, and annual exotic vet visits are the four biggest factors in maximizing lifespan.
Pros and Cons of Owning a Rex Rabbit
| Pros | Cons |
| Exceptionally soft, low-shed coat | Requires exotic vet — harder to find |
| Calm, beginner-friendly temperament | Sensitive feet (sore hocks on hard floors) |
| Two size options (Standard + Mini) | Needs 3–4 hours daily exercise |
| Highly trainable with treats | Fragile spine — not for very young children |
| Long lifespan (up to 12 years) | Can become depressed without social interaction |
| Recognized show breed (ARBA) | Spay/neuter strongly recommended for health |
Cost of Ownership: First-Year Estimate
| Expense | Cost (USD) |
| Rex Rabbit (from breeder) | $25–$100 |
| Exercise Pen + Rug | $60–$110 |
| Spay/Neuter (exotic vet) | $175–$800 |
| First Exotic Vet Exam | $70–$120 |
| Annual Timothy Hay | $100–$200 |
| Pellets + Fresh Greens | $80–$150 |
| Litter Box + Paper Litter | $30–$60 |
| Toys + Enrichment | $50–$100 |
| Year 1 Total | ~$590–$1,640 |
Always find a rabbit-savvy exotic vet BEFORE bringing your Rex home. Emergency vet visits for GI Stasis — the #1 rabbit killer — can cost $300–$1,500 if not caught early.
Rex Rabbit Diet and Feeding Guide
A proper diet is the single most important factor in your Rex rabbit’s long-term health.
| Food | Amount | Purpose |
| Timothy Hay | Unlimited (70% of diet) | Dental wear + digestive motility |
| Fresh Leafy Greens | 1 cup per 2 lbs body weight | Vitamins and hydration |
| High-Fiber Pellets | ¼ cup per 6 lbs body weight | Concentrated nutrients |
| Fresh Water | Always available | Ceramic bowl preferred over bottle |
| Treats | Max 1 tsp per day | Positive reinforcement only |
Foods to avoid: Iceberg lettuce (causes diarrhea), sugary fruits in large quantities, bread, crackers, cereals, and any processed human food.
Housing and Environment
Rex rabbits can live indoors or outdoors, but indoor housing is strongly preferred by the House Rabbit Society. Indoor rabbits live significantly longer due to protection from predators, extreme temperatures, and respiratory illness.
Minimum housing requirements (ARBA/HRS guidelines):
- Exercise pen: Minimum 8 sq ft living space + 24 sq ft daily exercise area
- Flooring: Low-pile rugs or foam mats — never wire flooring
- Litter box: Paper-based pellet litter (never cedar or pine — toxic to rabbit liver)
- Hideout: At least one enclosed dark space (cardboard box or wooden hide)
- Temperature: Keep between 60–75°F — Rex rabbits are highly heat-sensitive above 80°F
Sore Hocks: The Rex Rabbit’s #1 Breed-Specific Risk
Sore hocks (ulcerative pododermatitis) is a painful condition where the skin on the bottom of a rabbit’s hind feet becomes raw, inflamed, or infected. Rex rabbits are at significantly higher risk than other breeds because their foot fur is thinner due to the same genetic mutation that gives them their velvety coat.
Prevention:
- Always provide soft flooring — rugs, fleece mats, or foam tiles
- Never house on wire mesh flooring
- Keep the litter box clean and dry — wet litter is the primary cause
- Check the bottom of their feet weekly for redness or hair loss
Treatment: If you notice raw or bleeding spots on the feet, this requires an immediate exotic vet visit. Untreated sore hocks can lead to bone infection (osteomyelitis).
Bonding and Companionship
The House Rabbit Society strongly recommends keeping rabbits in bonded pairs because solitary rabbits experience genuine loneliness and can develop depression-like behaviors (bar-biting, over-grooming, lethargy).
- Best pairing: Two neutered/spayed Rex rabbits of any sex combination
- Bonding process: Takes 2–6 weeks of neutral-territory meetings in a space neither rabbit has claimed (a bathroom works well)
- Signs of successful bonding: Mutual grooming, sleeping side-by-side, synchronized Zoomies
- Single rabbit rule: If keeping one Rex, commit to a minimum of 3–4 hours of active daily interaction. Without companionship, Rex rabbits can develop stress behaviors within weeks.
Grooming and Hygiene
Rex rabbit fur requires less maintenance than most breeds, but their unique coat needs specific care:
- Brushing: Once or twice per week with a soft rubber grooming mitt — never a wire slicker brush, which damages the delicate velvet texture
- During molts: Daily gentle brushing — ingested fur causes dangerous intestinal blockages since rabbits cannot vomit
- Nail trimming: Every 4–6 weeks with small animal clippers
- Ear checks: Weekly — look for dark waxy debris (ear mites) or redness (infection)
- Never bathe with water: Full baths cause hypothermia and shock. Spot-clean with a damp cloth only.
Common Health Issues
| Health Issue | Signs | Prevention |
| GI Stasis | No eating/pooping 8+ hours | Unlimited hay access |
| Overgrown Teeth | Drooling, reduced appetite | 80% hay diet |
| Sore Hocks | Red/raw foot pads | Soft flooring, dry litter |
| Uterine Cancer (females) | Lethargy, blood in urine | Spay before age 2 |
| Obesity | Sluggish movement, fat rolls | Limit pellets + treats |
| Ear Mites | Head shaking, dark ear debris | Weekly ear checks |
Training and Mental Stimulation
Rex rabbits are among the most trainable rabbit breeds in the US thanks to their food motivation and natural curiosity.
Training techniques:
- Litter training: Place litter box in the corner they naturally choose — most Rex rabbits train within 1–2 weeks
- Name recognition: Say their name each time you offer a treat. Most learn within 2–3 weeks
- Trick training: Using cilantro or a small pea, Rex rabbits can learn to spin in a circle, stand on hind legs, or jump through a hoop
Enrichment must-haves:
- Dig box (shallow tray with shredded paper)
- Willow chew balls and applewood sticks
- Cardboard tunnel system
- Treat puzzle feeders — hide pellets inside toilet rolls
Rotate enrichment weekly. A bored Rex rabbit redirects energy to baseboards, carpet corners, and electrical cords.
