The Sphynx breed originated from a spontaneous genetic mutation. In 1966, a domestic shorthair in Toronto gave birth to a hairless male kitten named Prune. Breeders recognized the potential of this recessive gene and, through careful outcrossing and selection, developed the breed we know today. It's important to note that most Sphynx cats are not completely hairless; they typically possess a fine, suede-like down.

Devon Rex Origins

English Discovery:

• Origin: Devon, England
• Discovery: 1960
• Founder: Kirlee (a stray cat with a unique curly coat)
• Development: A dedicated breeding program established the breed standard.

The Devon Rex began with Kirlee, a stray cat discovered in Devon, England, who possessed an unusual curly coat and large, bat-like ears. Genetic testing later confirmed that the Devon Rex's curl is caused by a different, recessive gene than that of the Cornish Rex (found in neighboring Cornwall). Selective breeding preserved and refined these distinctive traits.

Temperament Comparison

Special Care Requirements

Sphynx Skin Care (High Maintenance)

Weekly Routine is Essential:

1. Bathing: Weekly to bi-weekly with a gentle, pH-balanced cat shampoo to remove oil buildup.
2. Ear Cleaning: Weekly cleaning to prevent wax and oil accumulation in their large ears.
3. Nail Care: Weekly cleaning of the nail beds where oil collects.

Environmental Needs:

Devon Rex Coat Care (Low Maintenance)

Minimal Grooming Required:

1. Brushing: A weekly gentle brushing with a soft brush or grooming with your hands is sufficient. Avoid over-brushing, which can damage the delicate curls.
2. Bathing: Only occasionally needed (every few months) if their coat becomes greasy.
3. Ear Cleaning: Weekly checks and cleaning due to their large ear size.

Environmental Needs:

• Standard cat comforts are adequate. They appreciate warm beds but don't have the same critical need for external heat sources as the Sphynx.
• Provide plenty of vertical space (cat trees) and interactive toys to channel their high energy.

Health Considerations

Sphynx Health Issues

Common Concerns:

1. Hypertrophic Cardiomyopathy (HCM): A form of heart disease. Regular cardiac screening is recommended.
2. Skin Conditions: Prone to yeast or bacterial infections due to oil buildup; sunburn is also a risk.
3. Dental Issues: Periodontal disease can be common; establish a dental care routine early.

Devon Rex Health Issues

Common Concerns:

1. Hypertrophic Cardiomyopathy (HCM): As with Sphynx, regular cardiac screening is advised.
2. Patellar Luxation: A condition where the kneecap dislocates.
3. Hereditary Myopathy: A rare genetic condition causing muscle weakness (most lines are now clear).

Preventive Care for Both: Regular veterinary check-ups, a high-quality diet, and maintaining a healthy weight are crucial.

Cost of Ownership

Initial & Annual Costs (Estimates)

Lifetime Cost Estimate (14 years):

• Sphynx: $27,000 - $40,000+

Frequently Asked Questions (2026)

Q: Are Sphynx cats hypoallergenic? A: No cat breed is 100% hypoallergenic. The primary allergen (Fel d1) is in saliva and skin oils. While Sphynx cats lack fur to shed the allergen, they still produce it. Some allergy sufferers tolerate them better, but individual reactions vary widely.

Q: Do Devon Rex cats shed? A: Yes, but minimally. Their short, curly coat sheds far less than that of a typical domestic shorthair. You will likely notice less hair on furniture and clothing.

Q: Can Sphynx cats go outside? A: Absolutely not. They are highly vulnerable to sunburn, frostbite, and skin injuries. They must be indoor-only cats.

Q: Are these breeds good for first-time cat owners? A: Generally, no. The Sphynx's specialized care and the Devon Rex's high energy and intelligence are better suited to experienced cat owners who understand feline needs deeply.

Q: Why do Sphynx cats feel so warm? A: With little to no fur to insulate them, their body heat is directly transferred to your touch. Their normal body temperature is also slightly higher than that of furry cats.

Disclaimer: Both the Sphynx and Devon Rex are wonderful but demanding breeds with unique needs. Thorough research and preparation are essential before welcoming one into your home. Always seek a reputable breeder who performs health screenings.
