A Rex rabbit brings two heatwave complications that rarely appear on the same care list. The first is his coat: the Rex mutation produces a short, extraordinarily dense, plush pelt that feels like velvet and insulates like it too, trapping warm air across his whole body. The second is his feet: Rex rabbits are known for thinner fur on their hocks, and the classic heatwave advice — let the rabbit sprawl on hard tile — can rub sore spots onto a Rex's heels when he does it for hours a day.
Cooling a Rex without punishing his hocks
Bring your Rex's pen into the coolest indoor room and give him a choice of surfaces rather than a single cold floor. Lay a ceramic tile on one side of the pen for maximum belly-cooling, and a padded mat or folded fleece on the other, so he can alternate: tile when he is hottest, softness when his hocks need relief, which Rex rabbits will do instinctively if both options exist. Check his hocks every day of the heatwave — part the fur on the back of each hind foot and look for balding patches, pinkness, or broken skin; catching thinning fur early, and adding more padding, is what stops a hot week from becoming a sore-hock problem that lingers long after the weather breaks.
What the plush coat changes about cooling a Rex
Do not soak a Rex to cool him. That dense plush coat holds water against the skin instead of shedding it, dries slowly, and leaves him damp and uncomfortable while the skin underneath stays warm; it also ruins the coat's texture for days. The cooling that works for a Rex is environmental and conductive: the coolest room you have, tile contact, the frozen bottle, gentle air movement across the pen, and cool water lightly applied to the outer ears, where his coat does not interfere.
Keep a Rex eating and drinking when the room is hot
A Rex who parks himself on the tile and stops visiting the hay rack is the pattern to interrupt. Keep unlimited hay within reach of his cool resting area so grazing does not require sitting somewhere warm, and refresh his water bowl twice daily; offer his usual greens rinsed and wet for extra fluid. Also watch how he moves when he does get up — a Rex shifting weight off his hind feet or reluctant to hop may be telling you his hocks hurt, which heatwave sprawling can trigger, and sore hocks that break the skin need a veterinarian's attention.
Heat-stress signs in a Rex, and the fast response
Fast breathing with flared nostrils, ears hot to the touch, drooling, a wet chin, and lying flat and unresponsive are heat-stress signs in a Rex, as in any rabbit — but do not let his normally plush, sleepy look talk you out of checking. Move him to the coolest spot available, dampen his ears with cool water, offer water, and call a veterinarian immediately; a rabbit insulated by that coat can be deeply overheated while his surface still feels deceptively normal to a casual hand. If you find a hock that is open, weeping, or clearly painful at the same time, mention it on that call, because the two problems together change his care.
Keeping Rex checks from slipping during a long hot spell
The Rex routine has more moving parts than most — bottle swaps, tile time, hock inspections, dropping counts — spread across a heatwave that may run a week. KinsLe Care Teams lets you divide those exact jobs among the people in your household, each marked complete as it is done, so your Rex's hocks get looked at on the busy days and not only on the quiet ones.
