A moderately warm band for a Devon Rex
A Devon Rex kept indoors suits a room temperature of about 70 to 76 degrees — warmer than a thick-coated cat needs, short of the near-tropical setup owners sometimes imagine. Her coat is a short, loose wave with minimal guard hair, her body is small and fine-boned, and her famously large ears are thin and lightly furred, radiating heat away. Within that band she relaxes, plays and sleeps out in the open. Below it she goes looking for supplementary heat, and her behaviour, not the thermostat display, is the more honest instrument.
How a Devon Rex shows the room misses her range
A Devon Rex who is too cool becomes a shoulder cat, a lap cat and an under-the-duvet cat in rotation, tucking herself against any warm body available and sitting hunched with her paws pulled in tight. She may claim the top of a warm appliance and resist being moved from it. A Devon Rex who is too warm does the opposite tour: hard floors, stretched postures, rooms away from the sun, and a sudden disinterest in the hooded bed she adored all winter. Either itinerary, repeated daily, is her review of your temperature setting.
Short dips are not emergencies. Houses cool overnight and warm by afternoon, and a healthy adult Devon bridges those swings with bedding and body contact. The pattern to fix is the all-day, every-day compensation routine.
Microclimates matter more than one number
Because a Devon Rex is small, she lives in microclimates: the two degrees between floor and sofa height, the cold pool beside a patio door, the warm shelf above a radiator. Set the house in her band, then finish the job locally. A covered bed or blanket nest in her main room gives her a pocket several degrees warmer than the room when she wants it. In air-conditioned summer rooms, that same covered bed shields her from the vent's cold stream, which matters more to her than the room's average reading. Place water where she rests in hot weather so she drinks without crossing a room she finds chilly or stifling.
Avoid sealing her into the warmest room as the solution. She wants her people as much as her temperature, and a Devon shut away from the household will cry to rejoin it at almost any temperature.
Adjusting through the year for a Devon Rex
In winter hold the upper half of her range in the rooms she uses and expect her under blankets; in a heatwave drop toward the lower half, close sunny blinds and offer tile or stone floors for sprawling. Senior Devons, kittens and cats recovering from illness sit at the sensitive end of the band in both directions, so check on where they are actually sleeping during weather extremes instead of assuming the usual spots still work. A simple room thermometer at cat height in her favourite room often explains behaviour the wall thermostat never predicted.
Call a veterinarian if she shivers despite a warm bed and blankets, pants or drools in a hot room, stops eating during a weather swing, or feels limp and unresponsive — those signs move the problem past bedding and thermostats.
One range, shared by everyone who sets it
Thermostats get adjusted by whoever passes them, which is how a Devon Rex ends up in a freshly chilled house. Write down her 70-to-76 band, her covered-bed location and her summer cool floor, and keep it with her everyday profile. Saving those Devon Rex room preferences in KinsLe Family Sharing means every person in the home works from the same numbers instead of their own comfort.
