What is a healthy weight for a Cornish Rex cat?

Between 2.5 kg and 4.5 kg (5.5–9.9 lb) for most adults, with females typically lighter (2.5–3.5 kg) and males heavier (3.5–4.5 kg). Body condition score is the best guide, as frame size varies between individuals.

My Cornish Rex looks very skinny — is that normal?

The breed naturally looks leaner than most cats due to its fine bone structure, minimal coat, and slender physique. Check body condition: if ribs have a small amount of tissue covering and the cat is active and healthy, lean appearance alone is not concerning. If ribs feel sharp with no covering at all, or if the cat is lethargic or losing weight, see your vet.

Can a Cornish Rex be overweight despite looking slim?

Yes, though less commonly than in heavier-coated breeds. If rib palpation requires firm pressure, the waist tuck has disappeared, or the cat's agility has noticeably reduced, these are signs worth investigating even on a naturally slender breed.
