What is the ideal weight for an adult Devon Rex?

Most adult Devon Rex cats are healthy between 2.7 and 4.5 kg (6–10 lb). Females typically fall in the lower part of this range and males toward the upper end. Body condition score is more informative than weight alone.

My Devon Rex looks very thin. Is that normal for the breed?

The Devon Rex is naturally lean and fine-boned, and a healthy individual can look quite slender compared to heavier breeds. However, if you can see ribs, hip bones, or vertebrae clearly without touching the cat, or if muscle mass feels reduced, a vet check is warranted to rule out underweight or health issues.

How do I check my Devon Rex's body condition at home?

Run your fingers gently along the ribcage. At an ideal body condition (BCS 4–5/9), you should feel ribs clearly with light pressure but without prominent protrusions. Check for a visible waist taper from above and no swinging abdominal fat pad when walking.
