You are feeding a Devon Rex too much when its slight, pixie build starts to lose definition: the waist narrows less sharply behind the ribs, the belly hangs a little instead of staying trim, and your fingers have to press to find ribs that should sit close under that short, rippled coat. The Devon Rex is a small-to-medium cat with huge ears, long legs, and a mischievous, food-obsessed streak, so the honest evidence comes from hands, scales, and a realistic account of everything this talented thief actually eats.
The Devon appetite problem: theft counts as feeding
A Devon Rex does not limit its intake to what you serve. This breed is famous for stealing food from plates, worktops, other pets, and unsecured bins. A cat can be overfed while its official meals look modest, because the unofficial menu — toast crusts, a stolen chicken skin, the dog's leftovers — never gets counted. When you assess this breed, assess the whole day's eating, including what disappears when nobody is watching.
Shape checks tuned to a Devon Rex
Look down at your standing Devon Rex from above: a correctly fed Devon shows a definite waist between ribcage and hips, giving the body a light hourglass line. From the side, the tummy should stay fairly level and trim, not swing below the chest line. Stroke along the ribs with flat hands; you should feel each rib readily under a thin covering, and the cat's chest should feel firm and muscled rather than spongy. Because the Devon's wavy coat is short and fine, padding shows sooner than on a longhaired breed — a softness spreading over the shoulders and at the tail base is an early, visible warning worth acting on.
Weigh and record, because small cats hide small gains
A Devon Rex is a light cat, so an amount of gain that would be trivial on a large breed is proportionally serious here, and it arrives gradually enough that daily handling normalises it. Weigh your Devon monthly — a cat carrier on bathroom scales works — and keep a written record. Pair the trend with photographs taken from above every couple of months; the top-down picture exposes a vanishing waist that fond eyes forgive. If the record climbs while the waist fades, the diagnosis is plain: intake exceeds need, wherever those calories are sneaking in.
Cutting back in a house with a food thief
Reduce the measured meals slightly, then attack the unofficial supply. Move human food out of reach, fit a lid the cat cannot defeat on the bin, feed other pets behind a closed door, and clear plates promptly, because a Devon Rex experiences an unattended plate as an invitation. Swap edible rewards for the things this breed loves nearly as much — shoulder rides, fetch games, and warm laps — and use puzzle feeders to stretch a smaller portion into a longer, more satisfying hunt. Keep every feeder in the house working from the same measured amount so generosity at one meal is not quietly undoing restraint at another.
When gain in a Devon Rex needs veterinary input
See your veterinarian if your Devon Rex keeps gaining after meals are measured and theft is controlled, since unexplained gain in a normally slight, active breed deserves a proper check. Book promptly if the weight rise comes with new tiredness, increased thirst, breathing effort after mild play, or a belly that looks round and tight rather than softly padded. Take your weight record and a truthful list of the cat's known raids; that honesty helps the vet judge quickly. Back home, KinsLe's Care Teams keep the new feeding plan shared and visible, with each meal ticked off and time-stamped by whoever served it, which suits a breed always scouting for a duplicate dinner.
