Full trait-by-trait breakdown

Which one should you choose?

Both breeds are highly social, vocal, and people-focused, so this comparison is less about temperament category and more about degree and coat. Few cats narrate their day as constantly as a Siamese does, while the Devon Rex talks less but makes up for it with near-constant physical interaction and curiosity.

Coat is the clearer divider: the Devon Rex's sparse, wavy fur sheds very little but needs attention to warmth and occasional skin care, while the Siamese's short, fine coat is close to wash-and-go and sheds minimally without any special skin considerations. Build differs too — the Siamese carries a slender, long-lined frame, while the Devon Rex stays compact, with an elfin face and oversized ears.

A household that wants a highly vocal, opinionated companion and doesn't mind frequent conversation should lean Siamese. A household that wants an equally attention-hungry cat but with less noise, and is willing to keep the house warm and manage the coat's specific needs, should lean Devon Rex.
