What appetite and weight changes are common in an aging Devon Rex?

Published October 30, 2026

The short answer

An aging Devon Rex, famously food-enthusiastic, may surprise you by becoming choosier, grazing instead of finishing meals, and losing muscle around the shoulders despite a still-round tummy. That contrast matters because Devons carry weight unevenly as they age, and a playful appetite one week can mask a steady decline the next. Feel for condition during lap time and log meals alongside weight rather than trusting enthusiasm alone. With KinsLe, Pet Passport lets you keep your Devon Rex's meal patterns and vet findings together so changes are easy to show, not just describe.

The Devon Rex pattern as the years add up

Appetite in an aging Devon Rex often stays emotionally enthusiastic while the amount actually eaten quietly shrinks. The cat may still trot to the kitchen, watch food being prepared with those large ears forward, and then eat only a few mouthfuls before losing interest. Weight change can go either way at first: some senior Devons gain soft weight around the abdomen as activity drops, while others lose muscle from the neck, shoulders, and hindquarters, so the number on the scale barely moves while body shape changes a great deal. Owners who know this breed's pixie face well may notice the cheeks looking less full before the body looks thinner.

Reasons enthusiasm and intake part company

Several age-related shifts explain why an aging Devon Rex begs yet under-eats. Dulling smell reduces the reward of food that once smelled strong, dental discomfort can make the first bites promising and later bites sore, and a slower gut can leave the cat feeling full sooner. The Devon Rex also has a fine, short coat and a relatively lean build, so an older cat who spends more time curled up asleep expends less energy and may need frequent small meals rather than two large ones to take in enough. A sudden increase in appetite paired with weight loss is a different signal from fussy grazing and should not be dismissed as a quirk of the breed.

Reading body condition under a short coat

Hands-on checks suit an aging Devon Rex better than visual checks alone. During a settled lap cuddle, stroke along the ribs and spine: a healthy senior should feel smooth over the ribs with light pressure, without the spine standing out in sharp points. Look from above for a waist behind the ribs and from the side for whether the belly hangs lower while the back looks narrower, a combination that suggests fat gain alongside muscle loss. Photographing your Devon from the side and above each month, in the same light and spot, gives you a comparison that day-to-day familiarity hides.

Thresholds that should prompt a prompt booking

Contact a vet soon if an aging Devon Rex loses interest in food for a full day, vomits repeatedly, drinks noticeably more, or loses visible condition over a few weeks despite seeming keen at mealtimes. A ravenous appetite combined with weight loss, restlessness, or a faster-feeling heartbeat also deserves a timely appointment, because in a senior cat that pairing is a pattern vets want to investigate rather than watch indefinitely. Note changes in litter habits, vocalising at night, and willingness to jump onto favourite perches, since those details round out the picture you bring. Dental pain signs such as chewing on one side or dropping kibble belong on that same list.

Small adjustments that help a senior Devon eat well

Practical help for an aging Devon Rex centres on portion rhythm and comfort. Split the daily ration into three or four small servings, serve food at room temperature or slightly warmed to release scent, and keep the feeding spot away from litter and household traffic. If crunchy food is being left, offer a softer texture alongside and note the response over several days instead of swapping the whole diet overnight. Weigh weekly and keep serving notes brief but dated, so you can see whether a good week was a trend or an exception. Over time, KinsLe's Pet Passport holds your Devon Rex's weights, texture preferences, and examination notes in one place for whoever examines him next.
