Special Considerations for 2026 Owners

For Allergy Sufferers

Manage Your Expectations:

• Spend extended time with the breed before committing.
• Allergens are present in saliva and skin oils; regular cleaning of the cat and your home is key.
• Individual reactions vary greatly—what works for one person may not for another.

For Cold Climate Living

• Sphynx: Presents a significant challenge. Higher heating bills and a full wardrobe of sweaters are mandatory.
• Devon Rex: Much more manageable. Their coat provides some insulation, and standard indoor care suffices.

For Busy Lifestyles

• Sphynx: Not ideal. Their need for routine baths, skin care, and warmth requires a consistent time investment.
• Devon Rex: A better fit. While still social and playful, they are more independent and have lower grooming demands.

Final Verdict

Both the Sphynx and Devon Rex offer extraordinary companionship but cater to different lifestyles.

• Choose the Sphynx for an unparalleled, tactile bond and striking appearance, accepting the high-maintenance care that comes with it.
• Choose the Devon Rex for a playful, mischievous, and acrobatic friend with easier grooming needs, ready to bring constant energy to an active home.

Finding a Reputable Breeder in 2026

Essential Questions to Ask:

• Can you provide documentation for HCM and other genetic health screenings?
• What is the health history and temperament of the parent cats?
• Do you offer a health guarantee for your kittens?
• Can I visit to see the living conditions and meet the parents?
• What support and care guidance do you provide after adoption?

Major Red Flags:

• Breeders who cannot or will not show health test results.

• Prices significantly below market average.
• Unwillingness to let you see where the cats are raised.
• No questions asked about the home you will provide.

Pro Tip: Always consider breed-specific rescues and shelters. Wonderful adult cats often need loving homes.
