About Cornish Rex

Cornish Rex cats are slender, fine‑boned, and elegant, with large ears and a distinctive egg‑shaped head. Their short, wavy, velvet‑soft coat needs gentle care and warmth. Extremely active, playful, affectionate, and people focused, they crave interaction, mental stimulation, and indoor living.
