Origin and History
The Devon Rex has its roots in Devonshire, England (1960 natural mutation). Playful, mischievous, people-oriented, likes warmth; jumps on people; described as ‘pixie-like’; highly social — characteristics that have made the breed consistently popular with cat owners around the world.
The breed’s history reflects the qualities that define it today. Devon Rexs were developed through careful selection for specific traits: their distinctive appearance, temperament, and adaptability. Today, the Devon Rex is recognized by the CFA under the Rex group and has a dedicated global following of breeders and enthusiasts who work to maintain breed standards while prioritizing health through genetic screening.
Temperament
Devon Rexs are known for: Playful, mischievous, people-oriented, likes warmth; jumps on people; described as ‘pixie-like’; highly social
Understanding the Devon Rex’s temperament helps set realistic expectations for potential owners:
- Social needs: Devon Rexs require consistent human interaction and do not thrive when left alone for extended periods. If you work long hours, consider adopting a pair or ensuring regular enrichment.
- Activity level: High (mischievous, playful, monkey-like climbing ability; loves warm spots) — this should inform your decision about whether this breed fits your lifestyle.
- Communication: Each breed has its own vocal range. Devon Rexs communicate their needs through a combination of vocalizations and body language; learning to read your cat’s signals takes time but deepens the bond.
- Training: Cats can be trained. Devon Rexs, like all cats, respond best to positive reinforcement using high-value treats. Basic commands, leash training, and litter training are all achievable with patience.
Health Issues
Understanding Devon Rex Hereditary Health Risks
Devon Rexs, like all pedigreed cats, carry a specific set of hereditary health risks. Reputable breeders conduct DNA testing and cardiac screening to minimize the transmission of genetic diseases. Purchasing from a health-tested breeding program dramatically reduces (though does not eliminate) the risk of hereditary conditions.
Devon Rex Myopathy (Hereditary)
A muscle disease causing generalized weakness, head tremors, and difficulty swallowing. Inherited recessively. DNA testing is available.
Hypertrophic Cardiomyopathy (HCM)
HCM occurs in Devon Rex at moderate rates. Annual cardiac screening from age 2 is recommended.
Hip Dysplasia
Devon Rex have elevated hip dysplasia for a small breed — likely related to the mutation gene cluster.
Blood Type Incompatibility (Type B)
Devon Rex have a high prevalence of Type B blood — less common in most breeds. Type B queens bred with Type A toms produce kittens at risk for neonatal isoerythrolysis (a fatal blood incompatibility condition).
Skin Conditions
The fragile curly coat can develop bald patches easily; Devon Rex skin can become greasy. Regular gentle bathing is recommended.
Preventive Healthcare for Devon Rexs
Regardless of hereditary condition status, all Devon Rexs benefit from:
- Annual veterinary exams — baseline bloodwork, physical examination, dental assessment
- Dental care — professional cleanings every 1–2 years; at-home brushing 3–5 times weekly
- Parasite prevention — monthly flea/tick/heartworm prevention even for indoor-only cats
- Vaccination — core vaccines (FVRCP, rabies) on schedule; your vet will recommend non-core vaccines based on lifestyle
- Cardiac screening — echocardiography every 1–2 years for breeds with elevated HCM risk (consult your vet for Devon Rex-specific timing)
Grooming
Coat Care for Devon Rexs
Devon Rexs have a Short, very soft, curly/wavy coat; sparse in some areas; large ears; pixie-like appearance. Grooming requirements:
Frequency: Gentle brushing 1–2 times per week; bathing every 4–6 weeks for skin health
Tools needed:
- Stainless steel wide-tooth comb (for detecting tangles and removing loose fur)
- Slicker brush (for finishing and removing surface debris)
- Nail clippers or scratch pad (nails should be trimmed every 2–3 weeks)
- Cat-specific shampoo (for breeds requiring bathing)
Hairball management: Regular brushing removes loose fur before your Devon Rex ingests it during self-grooming. For long-haired Devon Rexs, adding a hairball-control food or supplement provides additional support.
Ear care: Check ears weekly; clean monthly with a veterinarian-recommended ear cleaner. Wax buildup and odor indicate a potential infection requiring vet attention.
Dental hygiene: Start dental care habits early — kittens who learn to accept tooth brushing as normal grow into cats who tolerate it as adults. Use cat-specific enzymatic toothpaste only (human toothpaste is toxic to cats).
Nutrition Requirements
Devon Rexs need a diet appropriate for their size (5–9 lbs), energy level (High (mischievous, playful, monkey-like climbing ability; loves warm spots)), and specific health considerations. The primary dietary focus for this breed: muscle support (myopathy), cardiac health, skin health.
Key nutritional priorities:
- Protein: Minimum 30% on dry matter basis; ideally 35–45% from named animal sources
- Taurine: Essential for cardiac health; all cats require dietary taurine — confirm supplementation in any food you choose
- Moisture: Incorporate wet food into the diet (20–30% of total calories minimum)
- Calories: Adjust portions based on body condition score, not just weight

Exercise and Indoor Environment
Activity Requirements
45–60 minutes of interactive play daily; multiple play sessions preferred
Environmental Needs
Devon Rexs thrive in an enriched indoor environment:
- Vertical space: Multi-level cat trees, wall-mounted shelves, and window perches provide necessary territory
- Scratching: Multiple scratching posts/pads (horizontal and vertical) prevent furniture damage and support natural claw maintenance
- Play variety: Rotate toys to maintain novelty — wand toys for interactive play, puzzle feeders for mental stimulation, and solo toys for independent play
- Safe outdoor access: A catio (enclosed outdoor cat enclosure) provides safe enrichment without the risks of free-roaming outdoor access
- Litter box: Minimum one box per cat plus one extra; larger breeds need larger boxes (minimum 18″ × 24″)

Frequently Asked Questions
Q: How much does a Devon Rex cat cost?
A: A Devon Rex kitten from a reputable CFA or TICA registered breeder costs $600–$2,000. Avoid purchasing from pet stores or breeders who cannot provide health testing documentation — the lifetime cost of treating preventable hereditary diseases far exceeds the purchase price difference. Adoption from a breed-specific rescue is a lower-cost alternative, with adult cats typically available for $100–$400.
Q: Are Devon Rexs good family cats?
A: Devon Rexs are generally good family cats, known for their playful, mischievous, people-oriented, likes warmth temperament. As with all cats, proper socialization from kittenhood — exposure to children, other pets, and varied household experiences — produces the most adaptable adult cats. Supervise interactions between young children and cats, and teach children how to interact respectfully with animals.
Q: Are Devon Rexs hypoallergenic?
A: No cat breed is truly hypoallergenic. All cats produce the Fel d 1 protein (in saliva, skin secretions, and urine) that triggers cat allergies in sensitive individuals. Some breeds produce lower Fel d 1 levels (Siberian, Balinese), but Devon Rexs are not specifically identified as low-allergen. Regular vacuuming, HEPA air filtration, and keeping cats out of bedrooms can reduce allergen exposure.
Q: How long do Devon Rex cats live?
A: Devon Rexs have an average lifespan of 10–15 years. Lifespan is influenced by genetics (hereditary disease load), diet quality, preventive healthcare access, and whether the cat is kept indoors (indoor cats live significantly longer than outdoor cats on average). Cats from health-tested breeding programs with proactive veterinary care tend toward the upper end of the lifespan range.
Q: Do Devon Rexs need a companion cat?
A: This depends on individual personality and the owner’s availability. Devon Rexs with high social needs (from the breed’s energetic or people-oriented temperament) generally do better with a feline companion if owners work long hours. For calmer, more independent Devon Rexs, a single-cat household is often fine. Assess your specific cat’s behavior — signs of loneliness (excessive vocalization, destructive behavior, over-grooming) suggest a companion would help.
