A Small Cat With a Fast Engine
The Cornish Rex is all fine bones and fine coat: a single soft, wavy layer with no guard hairs, a body that feels surprisingly warm to the touch, and a metabolism that runs accordingly. Rex cats are typically active, playful, and keen on food, often preferring several small meals to keep the engine fuelled. That build shapes today's question in two ways. First, appetite loss shows quickly, because there is little fat reserve and little coat to hide a changing outline. Second, comfort is thermal: a Rex who is cold, or housed somewhere draughtier than usual, may simply feel too unsettled to eat well, and will choose a heat source over the bowl.
Sorting Today's Refusal
Start with warmth and place. Is she camping on a radiator, under a blanket, or in the sun patch instead of eating, and has the house cooled, a window been left open, or her usual warm sleeping spot been moved? Then widen the check. A bright Rex who skips a meal but still plays, seeks laps, drinks, and uses the tray is likely having a minor day — a hairball is possible even in this short coat, a mild stomach upset from a stolen snack, or stress from visitors or a changed routine, which this sensitive, people-attached breed registers strongly. A Rex who stops seeking heat and company, sits hunched, or feels cooler and quieter than her warm, busy self has moved out of the minor category, and mouth soreness belongs on the list too if she approaches food and then backs away.
What to Do Across Today
Serve her normal food in small, fresh, slightly warmed portions — warming lifts the smell and suits a breed that grazes — in a warm, draught-free, calm spot away from other pets. Do not overhaul the diet today; novelty upsets stomachs and a Rex does not need a second variable. Make sure a genuinely warm resting place exists near, but not on top of, the feeding area, keep fresh water available, and invite a short play session before the evening meal to wake appetite up. Record each refusal and nibble with times, note litter output and any vomiting, and weigh her if she tolerates the scales, because in a cat this lean, small weight changes carry real information.
Thresholds Tuned to This Breed
A healthy adult Rex who is warm, bright, and drinking can be observed through a day of poor appetite, but do not stretch the watching: a complete refusal beyond a day, any kitten off food, or appetite loss combined with vomiting, drooling, hiding, or a cat who cannot get warm and settle needs the vet. Tell the clinic she is a Cornish Rex who has stopped eating; they will understand the thin margin the breed carries and why condition can slip quickly once intake stops.
Keeping Warmth and Appetite in the Record
Log today fully: room conditions, where she chose to rest, how much she ate and when, and how the episode ended. For this breed, the pairing of appetite with heat-seeking is a repeatable pattern, and two or three logged episodes will show whether refusals track cold snaps, household stress, or nothing obvious at all — the last of which is itself useful information for a vet. Filing those notes with weights and visit outcomes in KinsLe's Pet Passport keeps this delicate breed's history as well organised as her care needs to be.
