Temperament and behaviour
The Devon Rex has a playful, mischievous personality and loves being involved in absolutely everything their humans do. Unlike some more independent cat breeds, these little “pixies” are incredibly people-oriented and thrive on companionship, often following their owners from room to room or even perching on shoulders to stay close to the action.
These affectionate felines are also known for seeking out the warmest spots in the house, whether that’s a sunny windowsill, a cosy lap, or tucked under the duvet beside you. While they’re full of energy and curiosity, Devon Rex cats are equally devoted cuddle companions once they’re ready to settle down.
Despite their small size, Devon Rex cats are highly intelligent and surprisingly agile. With their “forever kitten” attitude, they love climbing, exploring high spaces, and investigating cupboards with their clever paws. Many can even learn tricks such as fetch or sit with positive reinforcement and patience.
They’re also famous for their huge appetites and enthusiasm around food, meaning mealtimes often become a family event whether invited or not! As Devon Rex cats are so social and active, they tend to do best in homes where they won’t be left alone for long periods. In return, they bring plenty of affection, entertainment, and humour to family life.
Devon Rex health problems
Devon Rex cats are generally considered a healthy breed, but like all pedigree cats, they can be more prone to certain genetic health conditions. Understanding these potential issues can help owners spot symptoms early and make informed decisions when choosing a kitten from a breeder.
Based on our 2025 claims data and average veterinary treatment costs, some of the issues more commonly identified in this breed include:
- Vomiting and diarrhoea – with an average claim of £514
- Cardiomyopathy – with an average claim of £581
- Tumour – with an average claim of £1,172
Not every cat will experience these issues. To reduce the risk of your Devon Rex doing so, choose a reputable breeder, keep up with routine vet check-ups, and support your cat’s overall wellbeing.
Also known as spasticity, Devon Rex myopathy is a rare genetic muscular condition caused by a genetic mutation. It usually affects kittens and young cats, leading to muscle weakness, particularly around the neck and shoulders. Some cats may appear wobbly, struggle to hold their head up, or experience difficulty swallowing when stressed or tired.
While there is currently no cure, many cats can still enjoy a good quality of life with supportive care, a calm environment, and simple adjustments such as raised food bowls. Responsible breeders can now DNA test for the condition, helping to reduce the risk of affected kittens being born.
Hypertrophic cardiomyopathy, often shortened to HCM, is one of the most common heart conditions seen in cats, including Devon Rexes. The condition causes the walls of the heart to thicken, making it harder for the heart to pump blood effectively.
Symptoms can sometimes be difficult to spot early on, but may include lethargy, rapid breathing, reduced appetite, or breathlessness. In some cases, vets may detect a heart murmur during a routine health check before symptoms develop. Although HCM cannot be cured, medication and regular veterinary monitoring can help manage the condition and support your cat’s quality of life.
Many reputable breeders now carry out routine heart screening on breeding cats to help lower the risk of passing the condition on to future generations.
Devon Rex cats can sometimes be prone to patellar luxation — a condition where the kneecap slips out of place. Some cats may briefly “skip” while walking or suddenly hold one leg up before carrying on normally again.
Mild cases may not cause significant discomfort and can often be managed through maintaining a healthy weight and supporting joint health. More severe cases may require surgery to improve mobility and reduce discomfort later in life. Regular vet check-ups can help monitor your cat’s joints as they age.
The Devon Rex’s unusual coat means they have less fur to absorb the natural oils produced by their skin. As a result, some Devon Rex cats can develop greasy skin, waxy ears, or irritation caused by yeast overgrowth.
You may notice symptoms such as frequent scratching, redness, a greasy coat, or dark discharge in the ears. Regular grooming and gentle ear cleaning can help keep their skin and ears healthy. Some owners also wipe their cat’s skin occasionally with a soft damp cloth to remove excess oils and prevent irritation.
What are the average costs of keeping a Devon Rex?
Bringing a Devon Rex into your home is a big commitment, but it can also be incredibly rewarding. In the UK, a Devon Rex kitten usually costs between £900 and £1,800. Kittens from reputable, registered breeders tend to be at the higher end of this scale, reflecting the cost of essential DNA health checks for the parents, vaccinations, and the careful socialisation that this affectionate, people-oriented breed needs in their early weeks.
But the costs don’t stop there. You should also plan for ongoing annual expenses of roughly £1,200 to £1,600. While their soft, “wash-and-wear” coats mean you won’t need to budget for professional grooming, you may find yourself spending a bit more on environmental comforts. Devon Rex cats have thin coats, so they often appreciate extra warmth — think high-quality heated beds or even cosy cat sweaters in colder months.
This yearly budget also covers premium nutrition to support their lively lifestyle, comprehensive cat insurance, and routine dental care. Investing in a Devon Rex’s health and happiness now can help prevent expensive vet bills later, and keep your feline friend thriving for years to come.
Grooming
Devon Rex cats have soft, wavy coats that are famously low-maintenance. Their “wash-and-wear” fur means they rarely need professional grooming. Regular gentle brushing helps remove loose hairs and keeps their skin healthy, and a quick check of ears and nails each week will keep your feline friend comfortable and looking their best.
Exercise
These lively, playful cats love to stay active. Providing daily opportunities to climb, jump, and chase toys will keep them physically fit and mentally stimulated. Interactive play with wand toys or fetch-style games is perfect for burning off energy and strengthening the bond between you and your Devon Rex.
Enrichment
Devon Rex cats are curious and intelligent, so they thrive on enrichment. Puzzle feeders, climbing structures, and new toys can help prevent boredom. Rotating toys and introducing small changes to their environment keeps them engaged and happy, while giving them plenty of cosy spots to nap satisfies their love of comfort.
Diet
A nutritious, balanced diet is key for this active breed. High-quality wet and dry foods rich in protein help support their energy levels and maintain a healthy weight. Because they have high metabolisms, feeding small, frequent meals throughout the day can keep them satisfied and prevent digestive issues.
Origins of the Devon Rex cat
The story of the Devon Rex began in 1960 in Buckfastleigh, Devon, when a local woman named Beryl Cox discovered a stray curly-coated kitten among a litter born near a disused tin mine. The kitten, later named Kirlee, was initially believed to be linked to the Cornish Rex breed, which had been discovered around a decade earlier. However, breeding programmes soon revealed that Kirlee carried an entirely different genetic mutation, making him the foundation of a completely new breed.
This unique discovery helped shape the Devon Rex we know today, famous for its soft, “crushed velvet” coat, oversized ears, and wide, mischievous-looking eyes. During the 1960s, breeders carefully worked to preserve the Devon Rex’s distinctive “pixie-like” appearance and affectionate personality, helping the breed quickly gain popularity both in the UK and around the world.
Unlike some cat breeds with centuries of carefully documented history, the Devon Rex is considered a relatively modern breed and a true English original, proudly named after its Devonshire roots. Today, these playful and loving cats are adored for their unique looks, social nature, and entertaining personalities.
Did you know?
Because Devon Rex cats have such a fine, thin coat, they often feel much warmer to the touch than many other breeds. Some owners even describe them as feeling like a “living hot water bottle” when curled up beside them!
Playful, loving, and full of character
Devon Rex cats are affectionate, playful, and endlessly curious. They love being around people and often follow their favourite humans from room to room. This breed thrives on attention and enjoys interactive play, making them ideal for owners who can offer lots of companionship and mental stimulation.
Needs attention and warmth
While their affectionate nature is one of their biggest charms, Devon Rex cats can be demanding. They may not enjoy long periods of being left alone and require regular play and engagement. Their thin coats also mean they need extra warmth, especially in colder months, so you’ll need to provide heated beds or cosy spots for them to snuggle into.
Best for engaged and caring homes
Devon Rex cats are best suited to households where someone is often home or where they have another friendly pet for company. Families with older children or adults who understand a cat’s need for attention and gentle handling will find this breed a wonderful companion. They can adapt to busy households, provided they receive enough interaction and care.
Devon Rex FAQs
Devon Rex kittens are highly social and thrive on human interaction. They need plenty of daily attention, playtime, and mental stimulation to stay happy and healthy. Short, frequent play sessions using interactive toys or gentle games will keep them entertained, while cuddles and quiet bonding time help strengthen your relationship.
Without enough attention, they can become bored or anxious, so be prepared for a cat that loves to be involved in your daily life.
Early socialisation is key for Devon Rex kittens. Introducing them to different people, other pets, sounds, and environments helps them grow into confident, well-adjusted cats. Gentle handling, positive reinforcement, and consistent routines will make new experiences enjoyable rather than stressful. Because this breed craves interaction, starting socialisation while they’re young can prevent shyness or behavioural issues later.
Devon Rex cats are generally sociable and can get along well with other cats, dogs, and even small pets if introduced carefully. They appreciate company and often enjoy having a feline or canine companion to play with. Slow, supervised introductions and positive reinforcement are important, and each pet’s personality should be taken into account to ensure everyone feels safe and comfortable.
No cat is completely hypoallergenic, but Devon Rex cats are often recommended for people with mild allergies. Their short, fine coat produces less shedding and dander than many other breeds, which can reduce allergic reactions. However, allergy sufferers should still spend time with the breed before committing, and regular grooming and cleaning can help minimise allergens in the home.
