Many people with allergies dream of owning a cat without the sneezing and itchy eyes. The Cornish Rex, with its unusual curly coat, is often mentioned as a possible option for allergy sufferers.
These distinctive cats have a wavy, short coat that feels like velvet to the touch.

Despite what many websites claim, Cornish Rex cats are not truly hypoallergenic. While they may shed less fur than other breeds, they still produce the Fel d 1 protein in their saliva and skin oils that causes allergic reactions in humans.
When the cat grooms itself, this protein gets on their fur and eventually into your home environment.
You might find that your allergic reactions to a Cornish Rex are less severe than with other cats due to their reduced shedding. However, if you have cat allergies, it’s important to spend time with this unique cat breed before bringing one home.
Some allergy sufferers report fewer symptoms with Rex cats, while others experience the same reactions they would with any other feline.
Understanding Hypoallergenic Cat Breeds

Many people with allergies seek out hypoallergenic cat breeds hoping to enjoy feline companionship without uncomfortable symptoms. These special breeds produce fewer allergens or shed less than typical cats.
What Does Hypoallergenic Mean?
Hypoallergenic refers to something that’s less likely to cause an allergic reaction. With cats, this term can be misleading. No cat is truly 100% hypoallergenic, but some breeds produce fewer allergens.
The main cat allergen is a protein called Fel d 1, found in a cat’s:
- Saliva
- Skin oils
- Dander (dead skin cells)
When cats groom themselves, they spread this protein onto their fur. As they shed, these allergens disperse into your environment.
Breeds like the Cornish Rex, Devon Rex, and Javanese cats produce less Fel d 1 or shed less fur, making them better options for allergy sufferers.
Common Misconceptions
The biggest misconception is that cat hair itself causes allergies. In reality, you’re reacting to the proteins in the cat’s saliva and skin oils that get transferred to their fur.
Many people incorrectly believe hairless cats are completely allergy-free. While they don’t spread allergens through fur, they still produce the allergenic proteins on their skin.
Another myth is that certain breeds are completely hypoallergenic. Even low-allergen breeds like the Cornish Rex can trigger reactions in highly sensitive people.
Your individual sensitivity level matters too. Some people with mild allergies might do fine with a so-called hypoallergenic breed, while others may still experience symptoms.
The Cornish Rex Cat Profile

Cornish Rex cats stand out from other breeds with their unique curly coat and playful personality. These distinctive felines combine an athletic build with sociable nature, making them popular companions for many cat lovers.
Distinctive Features and Personality
Cornish Rex cats have a distinctive athletic build with long legs, a slender body, and large ears. You’ll notice their egg-shaped heads and high cheekbones that give them an elegant appearance.
These cats are incredibly playful and remain kitten-like well into adulthood. Their curious nature means they’ll explore every corner of your home and participate in family activities.
You’ll find Cornish Rex cats to be highly sociable, often forming strong bonds with their human families. They enjoy interactive play and can learn tricks easily due to their intelligence.
These active cats are known for their impressive jumping abilities and speed. They thrive in environments where they can exercise both their bodies and minds.
The Unique Coat of a Cornish Rex
The most remarkable feature of a Cornish Rex is their wavy coat. Unlike most cats with three layers of fur, Cornish Rex cats only have the undercoat – the soft, downy layer closest to the skin.
This fine hair grows in tight curls or waves across their entire body. When you pet a Cornish Rex, you’ll notice the coat feels incredibly soft, often compared to velvet or suede.
Their unique coat requires minimal grooming compared to other breeds. The short tight curl makes many people believe these cats might be hypoallergenic, though this isn’t entirely accurate.
The wavy fur comes in various colors and patterns. Due to their fine hair, Cornish Rex cats often feel warmer to the touch than other breeds, and you might notice them seeking warm spots around your home.
Cornish Rex and Allergies

Many people with cat allergies wonder if Cornish Rex cats might be a better option for them. These unique cats have distinctive curly coats that shed less than many other breeds, but this doesn’t necessarily mean they won’t trigger allergic reactions.
How Cornish Rex Cats Affect Allergies
Cornish Rex cats are often marketed as “hypoallergenic,” but this term can be misleading. No cat is truly hypoallergenic, as all cats produce allergenic proteins. The main allergen, Fel d 1, is produced in cats’ saliva, skin glands, and urine—not primarily in their fur.
When Cornish Rex cats groom themselves, they spread this allergen onto their coat. Their advantage comes from their unique coat structure: they lack the normal undercoat that most cats have, which means less hair to trap and spread allergens.
The Cornish Rex does shed minimally, which can reduce—but not eliminate—the amount of allergens in your home. This makes weekly brushing and regular bathing especially helpful in managing allergies.
Allergen Levels in Cornish Rex
Despite popular claims, Cornish Rex cats still produce the Fel d 1 protein that causes most allergic reactions in humans. Many websites incorrectly claim these cats are hypoallergenic, which can lead to disappointment for allergy sufferers.
The reduced shedding does mean fewer allergens spread around your home, but the cats themselves still produce the same allergens as other breeds. Individual Cornish Rex cats may produce varying levels of Fel d 1, with some producing less than others.
If you have cat allergies but want to try living with a Cornish Rex, consider:
- Spending time with a Cornish Rex before adopting
- Using HEPA air purifiers in your home
- Establishing “cat-free” zones, especially in bedrooms
- Regular grooming (ideally by someone without allergies)
Your reaction to a Cornish Rex will depend on your specific allergies and sensitivity levels.
Comparing Hypoallergenic Cat Breeds

For allergy sufferers looking for feline companions, understanding the differences between hypoallergenic cat breeds can help make the right choice. Several breeds produce fewer allergens than others, though none are completely allergen-free.
Cornish Rex vs. Other Hypoallergenic Breeds
The Cornish Rex stands out with its unique coat of tight, marcel waves that shed minimally. When compared to the Devon Rex, both share curly coats, but the Cornish Rex has a finer, more uniform wave pattern.
The Sphynx cat, unlike the Cornish Rex, has virtually no coat at all. While the Cornish Rex requires minimal grooming, Sphynx cats need regular bathing to remove oil buildup.
The Siberian cat surprisingly produces fewer allergens despite having a fuller coat than the Cornish Rex. Meanwhile, the Russian Blue produces less of the Fel d 1 protein that triggers allergies.
Traits of Other Hypoallergenic Cats
The Balinese cat and its close relative, the Javanese cat, produce less Fel d 1 protein despite their medium-length coats. They’re good options if you prefer a cat with more fur than the Cornish Rex.
The Oriental Shorthair and Siamese cat have short, fine coats that shed minimally, making them easier on allergies. Both breeds are known for their vocal and affectionate nature.
The Selkirk Rex differs from the Cornish Rex with its looser, plushier curls. It’s worth noting that standard tabby cats aren’t considered hypoallergenic, regardless of their coat pattern.
Remember that individual reactions vary, and some people with allergies may respond differently to each breed.
Health and Care Considerations
Cornish Rex cats require specific care routines to maintain their unique coats and overall health. Their distinctive physical traits demand attention to certain aspects of daily maintenance.
Regular Grooming and Care
Cornish Rex cats have minimal grooming needs compared to other breeds. Their short, curly coat doesn’t require frequent brushing, but you should gently wipe them with a soft cloth weekly to remove excess oils.
These cats may be extra greasy and waxy, making regular cleaning important. Their thin coat offers less protection, so keep them warm during colder months.
Monitor their skin for irritations or sunburn, as their minimal fur provides less natural protection.
Ear cleaning is essential for Cornish Rex cats. Check ears weekly for wax buildup and gently clean with a vet-approved solution. Their large ears can collect dirt more easily than other breeds.
Trim nails every two weeks and brush teeth regularly to prevent dental issues.
Diet and Health Monitoring
Cornish Rex cats may have sensitive stomachs that develop food sensitivities over time.
Monitor their reaction to different foods and consult your vet about appropriate diets.
High-quality protein should form the foundation of their diet. These active cats have fast metabolisms and may need more calories than other breeds of similar size.
Provide fresh water daily and consider a pet fountain to encourage drinking.
Proper hydration helps prevent urinary issues common in cats.
Watch for signs of yeast infections, as Cornish Rex cats can be more prone to them due to their coat type.
Regular vet checkups are important to catch potential health issues early.
Interactive play sessions help maintain healthy weight and provide mental stimulation. Aim for at least 15-20 minutes of daily play.
