A wide comfort band, with limits at both ends
A Selkirk Rex kept indoors settles happily in rooms held between about 66 and 76 degrees Fahrenheit. That comparatively wide band reflects the breed as it is built. The Selkirk's famous curls sit in a plush, dense coat with a real underlayer, quite unlike the fine single coats of the other Rex breeds, and the cat itself is solid, medium-to-large, and famously tolerant about the small disruptions of household life. A healthy adult Selkirk Rex in a mildly cool room will usually just curl into its bed and sleep contentedly. The ends of the band still deserve respect for a Selkirk Rex. Below the mid-sixties for long stretches, a young kitten, an elderly cat, or a Selkirk in a thin patch of its coat cycle will burn energy staying warm and may start hiding in bedding or behind appliances for heat. Above the upper seventies, that same plush coat traps warmth, and a cat that cannot move into a cooler room will go flat and quiet on hard flooring. The number on the thermostat matters less than whether the Selkirk Rex can always walk away from the warmest and coldest spots in the home.
Letting the curls do their work
A Selkirk Rex's coat is part of its temperature system, so the room plan and the grooming plan meet. Loose curls insulate best when the coat is clean and unmatted, because matted patches press the fur flat against the skin and leave the thinner areas exposed to cold air. Set up the Selkirk Rex's resting choice the way the breed itself prefers life — unhurried and varied. An enclosed, cushioned bed in a warmer room covers the cold end of the day. An open mat on a cooler floor, near but not inside the household's main traffic path, covers the warm end.
Seasonal shifts a Selkirk owner should expect
A Selkirk Rex may vote differently about the same room in different months, and owners sometimes misread that vote. In winter the cat may claim the bed nearest the heating source and abandon a summer perch by a window that now leaks cold air at the frame. In summer the same cat may spend afternoons stretched full-length on an entryway floor, using the tile as a heat sink under all that fur. Both moves are the Selkirk Rex regulating itself normally, as long as it is eating, playing, and greeting its people as usual. What should prompt a closer look in a Selkirk Rex is a change that does not match the weather. A cat that suddenly seeks heat constantly in a mild room, shivers, or loses interest in the play sessions this sociable breed usually joins deserves a veterinary check, because temperature-seeking that changes without the temperature changing can be the cat reporting that it feels unwell. Equally, a Selkirk panting in a hot room needs the room cooled and prompt veterinary advice if the breathing does not settle quickly once the cat is somewhere cooler.
Recording the setup so it survives a busy week
A Selkirk Rex is often the cat of a household that includes children, other pets, and visiting family, which means its warm bed gets moved, its cool room gets closed, and its window perch gets borrowed. A short shared note — the target range, which rooms stay open to the cat, and where its beds belong — keeps the arrangement intact when the person who designed it is not home. Keeping that home routine attached to the Selkirk Rex in KinsLe through Family Sharing means every helper restores the cat's chosen warm and cool spots instead of guessing.
