Visual Differences

Telling a Ragdoll from a Siamese

Siamese are fine-boned and tubular, with a short coat, a whip-thin tail, and a long tapering wedge head; Ragdolls are heavy, muscular, and semi-longhaired with a broad, rounded wedge head. Both are pointed with blue eyes, but Ragdoll patterns include white (mitted and bicolor), which the Siamese never has. Temperament differs too: Siamese are famously vocal and demanding, while Ragdolls are quiet and tend to go slack when picked up.

Telling a Siamese from a Ragdoll

Ragdolls are much larger, with a semi-long silky coat, a broad chest, and a plumed tail; Siamese are slender and tubular with a short, close-lying coat and large, wide-set ears. Both have blue eyes and color points, but the Ragdoll head is a broad, rounded wedge with full cheeks, while the Siamese head is a long, tapering wedge with a straight profile. Ragdolls go limp when lifted, which is how they got their name; a Siamese being held is usually planning an escape.

Frequently Asked Questions

How can I tell a Ragdoll apart from a Siamese?
Siamese are fine-boned and tubular, with a short coat, a whip-thin tail, and a long tapering wedge head; Ragdolls are heavy, muscular, and semi-longhaired with a broad, rounded wedge head. Both are pointed with blue eyes, but Ragdoll patterns include white (mitted and bicolor), which the Siamese never has.

How can I tell a Siamese apart from a Ragdoll?

Ragdolls go limp when lifted, which is how they got their name; a Siamese being held is usually planning an escape.
Do Ragdoll cats shed?
Yes — Ragdolls shed moderately year-round despite their silky single coat. Weekly brushing significantly reduces loose fur on furniture and clothing. Because they lack a dense undercoat (unlike Persians or Maine Coons), their shedding is generally less heavy than double-coated breeds, but they are not a low-shed or hypoallergenic breed. Expect some fur tumbleweeds, especially during seasonal coat changes.
Are Siamese cats hypoallergenic?
No — Siamese are not hypoallergenic. They produce normal levels of the Fel d 1 protein (the primary cat allergen found in saliva and skin oils) and shed dander like other shorthaired breeds. Their short coat may release slightly less airborne hair than longhaired breeds, but they are not considered a low-allergen breed. If you have cat allergies, spend time with a Siamese before adopting to test your individual reaction.
