Naked Skin vs Curly Waves
The biggest visual difference is the coat. Or the lack of it.
Sphynx
These guys are famous for being hairless. Most have a thin layer of peach fuzz that feels like warm suede. Without fur, you see every muscle and expression. Big ears, lemon-shaped eyes, and wrinkled skin give them that “alien but adorable” look. Skin shows color too—you’ll see spots, tabby patterns, and tortie right on the skin.
Cornish Rex
They have fur, but it’s nothing like a normal cat. No guard hairs or awn hairs — only soft, curly down. The result is a coat that waves like crushed velvet or marcel waves. Run your hand over them, and it ripples. Their bodies are slender with big ears and high cheekbones, so they look like a supermodel version of a cat.
Bottom line: Want a warm, suede-feeling companion that looks sculpted? Go Sphynx. Want a soft, wavy coat that stands out without being hairless? Pick the Rex cat.
Grooming: Baths vs Light Wipes
Less fur doesn’t always mean less work.
Sphynx grooming: No shedding, but their skin produces oils that fur would normally absorb. Skip baths, and you’ll get greasy skin, blackheads, and acne. Plan on a bath every 1-2 weeks using a gentle pet shampoo. Ears need cleaning 1-2x per week because wax builds up fast with no hair to catch it. Nails, too—oil stains fabric.
Cornish Rex grooming: Much easier. The curly coat doesn’t trap as much oil, so full baths are only needed every 6-8 weeks or when they get dirty. A damp cloth wipe for the ears/chin once a week handles most oil. Weekly brushing with a soft rubber glove removes loose curls and keeps the waves defined.
If you hate bath time, the Rex cat wins. If you don’t mind spa days with your pet, the Sphynx routine becomes bonding time.
Personality: Velcro vs Playful Acrobat
Both are people-oriented, but they show it differently.
Sphynx temperament: These are the “dog cats.” They crave contact and will follow you, sit on your shoulder, or sleep under your blanket. Leave them alone for 8+ hours, and they get stressed. They’re goofy, demanding attention, and make great therapy animals. Perfect for someone home most of the day.
Cornish Rex temperament: Just as affectionate, but with more independence and mischief. They’re kitten-like for life—climbing, jumping, chasing toys, and investigating everything. Smart breeds like this one learn fetch and puzzle toys fast. They’ll cuddle, but on their terms, usually after a play session.
Think: Sphynx = cuddle buddy 24/7. Cornish Rex = playmate who also cuddles.
Health & Temperature Sensitivity
Both are healthy overall, but their coats create special needs.
- Skin & temperature: Sphynx skin gets sunburned, dries out, and gets cold fast. You’ll need pet-safe sunscreen and sweaters for winter. Cornish Rexes are sensitive too, but less extreme because of their coat.
- HCM: Hypertrophic cardiomyopathy shows up in both breeds. Always buy from breeders who do annual heart scans. ICatCare HCM guide explains warning signs.
- Skin issues: Sphynx can get fungal infections or rashes if oils build up. Cornish Rex sometimes gets “stud tail” oil buildup at the base of the tail.
Lifespan is similar: 12-15 years with good care. Vet checkups every 6 months are smart for both.
Family & Pet Compatibility
Both thrive in busy homes. Sphynx cats do best with kids and other pets because they’re so tolerant and attention-hungry. They’ll accept a dog, another cat, or even a rabbit if introduced slowly. They fail in quiet, empty houses.
Cornish Rexes adapt well but need 2-3 days to warm up to new people or pets. Once they trust you, they become clowns. They’re gentler with play, rarely use claws, and are great for families with respectful kids. See our best breeds for kids list for more options.
Rule for both: they hate being alone. If you work long hours, get two cats or a pet sitter.
Trainability & Intelligence
Forget the “cats can’t learn” myth. These two are exceptions.
Sphynx cats learn tricks fast if food is involved. Leash training, sitting, and fetching are all doable at 4-6 months old. They’re motivated by attention.
Cornish Rex are problem-solvers. Clicker training works great. They figure out doors, cabinets, and puzzle feeders. Their athletic build makes them amazing at cat agility courses. If you like mental stimulation, you’ll be impressed.
Cost & Breeder Tips
Both are premium breeds. Expect $1,500-$3,000 from ethical breeders. Sphynx cats often cost more because breeding hairless cats is harder.
Red flags: breeders who don’t HCM test, kittens under 12 weeks, or “cheap hairless” ads online. Ask for TICA or CFA registration and health paperwork. A good breeder interviews you, too.

Final Verdict
Pick the Sphynx if you want a heat-seeking cuddle monster who treats you like their person. The weekly baths are worth it for that level of devotion.
Pick the Cornish Rex if you want a curly-coated athlete who entertains you with parkour and puzzles, but still sleeps on your chest at night.
Both will make your house louder, warmer, and way more fun. Just match the breed to your time, not just your taste.
FAQs
1. Which breed is better for allergy sufferers?
Neither breed is hypoallergenic. Allergies are usually triggered by Fel d 1 protein in saliva and skin, not fur. Some people react less to Sphynx because there’s no fur to trap dander, but others react more to skin oils.
2. Do they get cold easily?
Sphynx are very cold-sensitive due to no coat. They need sweaters in winter and warm beds year-round. Cornish Rex cats are sensitive to cold because of their thin fur, but they handle normal room temperatures better.
