Devon Rex vs Sphynx — at a glance

Energy levels are well-matched between the Devon Rex and Sphynx — both need similar daily exercise.

Grooming is where these breeds really diverge: the Sphynx needs significantly more brushing, washing and coat care. Factor in €30–€80 every 6–8 weeks for a professional groomer if you don't do it yourself.

Temperament

Energetic, mischievous, intensely social, attention-seeking. Sphynx cats often follow their humans like dogs and can be jealous of a single owner's attention.

Exercise

Very active. Need play, climbing, mental enrichment. Many do well with another cat for company.

Grooming

Surprisingly high. Weekly bathing is essential — skin oils that fur normally absorbs build up on the skin. Wipe ears weekly. Sphynx feel cold easily and may need sweaters in winter.

Health

Hypertrophic cardiomyopathy (HCM — DNA test). Skin issues. Heat sensitivity (sunburn risk). Dental disease.
