Care Needs

Very High HCM Risk

Sphynx cats have one of the highest rates of hypertrophic cardiomyopathy (HCM) of any cat breed. Annual echocardiograms are essential. Always buy from breeders who screen for HCM.

What Makes Sphynx Cats Unique

The Sphynx's hairlessness creates specialized care requirements that differ significantly from other cats:

  • No fur insulation: Cannot regulate body temperature effectively; needs warm environment
  • Visible skin oils: Without fur to absorb oils, skin becomes greasy and requires regular bathing
  • Higher metabolism: Burns more calories to stay warm; needs more food than average cat
  • Sun sensitivity: Vulnerable to sunburn through windows; may need pet-safe sunscreen
  • Ear wax buildup: No ear hair to trap debris; ears need weekly cleaning

Major Health Conditions

1. Hypertrophic Cardiomyopathy (HCM)

>30% affected

The most serious health concern for Sphynx cats. The heart muscle thickens, reducing efficiency. Can cause sudden death, heart failure, or blood clots leading to hind leg paralysis. Some lines have very high prevalence.

Warning signs:

  • • Rapid breathing at rest (>40/min)
  • • Open-mouth breathing
  • • Lethargy, exercise intolerance
  • • Loss of appetite
  • • Hind leg paralysis = emergency

Management:

  • • Annual echocardiogram (mandatory)
  • • proBNP blood test between scans
  • • Buy only from HCM-screened lines
  • • Medications if diagnosed
  • • Avoid breeding affected cats

2. Skin Problems

Very common

Without fur, skin oils accumulate on the surface causing various issues. The skin is also exposed to environmental irritants and allergens that fur would normally block.

Common issues:

  • • Oily skin and blackheads
  • • Urticaria pigmentosa
  • • Skin infections/yeast
  • • Sunburn
  • • Contact allergies

Prevention:

  • • Weekly bathing routine
  • • Gentle, cat-safe shampoo
  • • Daily wipe-downs between baths
  • • Clean bedding frequently
  • • Pet-safe sunscreen if needed

3. Temperature Regulation

Constant concern

Sphynx cats cannot maintain body temperature like furry cats. They lose heat quickly and can become hypothermic in cool conditions or overheated in direct sun.

Signs of temperature issues:

  • • Shivering (too cold)
  • • Seeking heat sources constantly
  • • Excessive panting (too hot)
  • • Lethargy
  • • Cool ears and paws

Management:

  • • Keep home 68-77°F (20-25°C)
  • • Heated cat beds
  • • Cat sweaters/clothing
  • • Sunny spots with shade option
  • • Never leave outside unattended

4. Dental Disease

Common

Sphynx cats are prone to periodontal disease and may develop dental problems earlier than other breeds. Regular dental care is essential.

Signs:

  • • Bad breath
  • • Red, swollen gums
  • • Difficulty eating
  • • Drooling
  • • Pawing at mouth

Prevention:

  • • Annual dental exams
  • • Professional cleanings
  • • Daily tooth brushing ideal
  • • Dental treats/water additives

5. Respiratory Infections

Increased susceptibility

Sphynx cats may be more susceptible to upper respiratory infections. Their lack of fur provides less protection from environmental pathogens.

Signs:

  • • Sneezing, nasal discharge
  • • Watery eyes
  • • Congestion
  • • Decreased appetite

Prevention:

  • • Keep vaccinations current
  • • Avoid drafts and cold
  • • Clean environment
  • • Prompt veterinary care

6. Digestive Sensitivities

Common

Many Sphynx cats have sensitive digestive systems. Combined with their higher caloric needs, finding the right diet can be challenging.

Signs:

  • • Frequent diarrhea or soft stool
  • • Vomiting
  • • Gas and bloating
  • • Food sensitivities

Management:

  • • High-quality, digestible diet
  • • Consistent feeding routine
  • • Probiotics may help
  • • Food trials if needed

Bloodwork Considerations for Sphynx Cats

When reviewing your Sphynx's bloodwork:

  • proBNP (cardiac biomarker): Critical for HCM monitoring between echocardiograms
  • Complete blood count: Monitor for infection/immune issues
  • Chemistry panel: Check liver and kidney function, especially with higher metabolism
  • Thyroid levels: Higher metabolism can sometimes mask thyroid issues

Use our cat blood test value checker to interpret results, keeping breed-specific concerns in mind.

Daily Care Requirements

Skin Care Routine

  • Weekly baths — use gentle, cat-safe shampoo; adjust frequency based on oil buildup
  • Daily wipe-downs — use pet wipes or damp cloth between baths
  • Weekly ear cleaning — no ear hair means more wax buildup
  • Nail bed cleaning — oils accumulate around nails during baths
  • Clean bedding frequently — oil transfers to fabric

When to See the Vet Immediately

Emergency Signs - Seek Immediate Care:

  • Sudden hind leg paralysis or weakness (blood clot from HCM)
  • Open-mouth breathing or severe respiratory distress

Frequently Asked Questions

What is the average lifespan of a Sphynx cat?

Sphynx cats typically live 9-15 years. Their lifespan is significantly affected by hypertrophic cardiomyopathy (HCM), which is very prevalent in the breed. Regular heart screening and selecting cats from HCM-tested lines is essential for longevity.

Do Sphynx cats have a lot of health problems?

Sphynx cats have several breed-specific health concerns: high HCM (heart disease) rates, skin issues from oil buildup, temperature regulation challenges, and dental problems. However, with proper care, regular vet visits, and heart screening, many Sphynx live healthy lives.

How often should I bathe my Sphynx cat?

Most Sphynx cats need bathing weekly or every 1-2 weeks. Without fur to absorb oils, their skin becomes greasy and can develop blackheads and infections. Use a gentle, cat-safe shampoo. Over-bathing can cause dry skin, so adjust frequency based on your cat's oil production.

Why do Sphynx cats get cold easily?

Sphynx cats lack the insulating fur coat that keeps other cats warm. They have a higher metabolism to compensate but still lose body heat rapidly. They need warm environments (68-77°F), heated beds, sweaters, and sunny spots to maintain body temperature.

What is HCM in Sphynx cats?

Hypertrophic cardiomyopathy (HCM) is a heart condition where the muscle thickens abnormally. Sphynx have very high HCM rates, with some studies suggesting over 30% are affected. It can cause sudden death or blood clots. Annual echocardiograms are essential for all Sphynx cats.

Can Sphynx cats go outside?

Sphynx cats should generally be indoor-only cats. Without fur, they're vulnerable to sunburn, skin damage, temperature extremes, and injuries. If supervised outdoor time is desired, use cat-safe sunscreen, avoid extreme weather, and never leave them unattended.
