Siamese vs Sphynx — at a glance

The Siamese (2.5–5 kg, 12–15 years) and the Sphynx (3.5–5 kg, 8–14 years) sit in different — or sometimes overlapping — corners of dog ownership. Here's how they really compare for an everyday Irish or UK family.

Energy levels are well-matched between the Siamese 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.

For allergy sufferers, the Sphynx is the lower-shed, more hypoallergenic option.

Siamese

Temperament

Vocal, social, intelligent, demanding. Siamese cats want to be involved in everything you do and will tell you about it loudly. They bond closely with one or two people and don't do well alone all day.

Exercise

Highly active and play-driven. Need interactive toys, vertical space, food puzzles. Many do well with a feline companion to play with.

Grooming

Short, fine coat. Weekly brushing is plenty.

Health

Generally healthy. Watch for: amyloidosis, asthma, dental disease, glaucoma, eyes (some lines have crossed eyes which is harmless), separation anxiety.

Sphynx

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.
