The Rex coat breaks under normal rabbit grooming
The mistake that harms a Rex is treating its velvet coat like any other rabbit's fur. A Rex carries very short, dense, upright hairs with guard hairs the same length as the undercoat, which is exactly what makes it feel like plush. Those short guard hairs snap easily, and a standard slicker or stiff brush dragged through the coat breaks them off at skin level. The result is patchy, bald-looking areas, often along the back and sides, that owners then brush more in an attempt to fix.
A Rex in good health needs its loose fur lifted, not its coat worked, and the gentlest tool for that job is a slightly damp hand.
What a moult does to velvet fur
A Rex moult tempts owners into the very brushing that harms it, because loose velvet fur comes away in visible clouds. During a moult the coat releases hair in patches, and the new coat underneath can look thin or uneven for a while. That unevenness is the moult's normal geography, not a problem brushing can solve. Working at the thin patches breaks the new short growth and turns a temporary stage into genuine baldness.
Stroking with a damp palm or a soft rubber grooming mitt picks up the released hair through light static and surface grip, without bending the standing hairs. Short daily stroking sessions through the heaviest week of a Rex moult remove more loose fur than one determined brush-out, and the rabbit usually leans into them instead of dodging.
Thin hocks and the Rex skin underneath
Rex skin runs thin under thin fur, and the breed is known for sore hocks when conditions conspire. The fur on a Rex's hind feet is sparser than on most rabbits, so the skin over the hock takes pressure directly. Grooming mistakes here include scrubbing at dirty hock fur, pulling matted bits off the feet, and ignoring early pinkness because the rabbit still hops normally.
Check the hocks during every grooming stroke session: part the foot fur gently and look for pink, hairless, or callused spots. Soiled foot fur is softened with a damp cloth and patted dry, never rubbed. Deep bedding, clean dry flooring, and nails kept trimmed so weight spreads evenly across the foot all protect Rex hocks more than any cleaning does. A hock that looks red, swollen, cracked, or is being guarded belongs to a veterinarian promptly, since foot sores worsen quickly once skin breaks.
Baths, powders, and other Rex no-goes
Bathing a Rex mats the velvet as it dries and strips the coat texture owners love, quite apart from the chilling and stress any rabbit suffers in water. Powders and dry shampoos cake in dense Rex fur and are licked out during self-grooming. Scented sprays sit on the coat surface and go the same route.
Nails and scent glands are the parts of Rex grooming that do need real attention. Nails grow long under all that plush presentation and need regular tip trims, and the scent gland folds either side of the genitals collect a waxy build-up that can be softened with a damp cotton bud and eased away gently.
One simple rule everyone in the house can follow
A Rex stays velvet when the household rule is short enough to remember: hands and a soft mitt only, never a brush. That rule matters most with visiting helpers and children, who reach for a brush because brushing is what grooming means to them.
Because the Rex routine is mostly what not to do, assigning the moult stroking, nail checks, and hock checks as named duties in KinsLe Care Teams gives every helper the same short instructions, so nobody improvises with a slicker.
