The Rex rabbit's daily amounts
A Rex rabbit needs unlimited grass hay every day — plan on a loose pile about the size of its own body, refreshed as it thins — plus roughly a third to a half cup of plain pellets and one to two packed cups of leafy greens. The Rex is a medium breed, typically around seven to ten pounds, and it sits between the dwarf and giant rations: more than a Lionhead eats, clearly less than a New Zealand. Fresh water in a bowl or bottle should be renewed daily, and most Rex rabbits drink more readily from a bowl.
Why the hay pile matters under that velvet coat
A Rex rabbit's plush, upright fur is the breed's signature, and the molars and gut underneath need the same long-strand fiber as any rabbit. Chewing grass hay sideways grinds the continuously growing back teeth, while the fiber itself keeps gut movement steady through the hair a Rex swallows while grooming that dense coat. A Rex that is filling up on pellets and picking at hay is on the road to dental and digestive trouble, so the hay rack should never sit empty to make room for a second pellet serving.
Pellets: the Rex weight trap
Rex rabbits have a well-earned reputation as enthusiastic eaters, and the breed gains weight readily when pellets are poured by eye. Measure the portion with an actual cup, choose plain hay-based pellets over colorful mixes a Rex can sort through, and split the ration into morning and evening servings so the day has two small events instead of one gorge. If your Rex is neutered, adult, and mostly indoors, start at the lower end of the range and let body condition — ribs felt under a light covering — argue for any increase.
Greens and treats that suit a Rex
Leafy greens give a Rex rabbit bulk and interest without pellet calories: rotate romaine, spring greens, coriander, and dandelion, adding one new kind every few days and watching that droppings stay round and dry. Herbs like parsley and mint work as the daily treat, fragrant enough to feel special at almost no caloric cost. Fruit and carrot stay occasional — a slice, not a handful — because sugar ferments in the hindgut and softens droppings in a breed already inclined to a generous waistline.
Moving a Rex onto a measured ration without a fuss
If your Rex rabbit has been free-feeding from a hopper, do not cut it to the measured cup overnight. Step the pellets down by a spoonful every few days across two weeks while the hay rack stays constantly full, so the Rex fills the gap with forage rather than hunger. Weigh at the start and again at the end of the changeover; a slow, steady trend toward ribs you can feel is the goal, not a sudden drop, and the greens bowl can stay generous throughout to keep the rabbit feeling fed.
Feet, weight, and when to call the vet
The Rex's fine, short foot fur offers less padding than other breeds, so extra body weight raises the risk of sore hocks; keeping the pellet measure honest protects the feet as much as the waistline. Check the soles monthly when you weigh. A Rex that stops eating, leaves its hay, or produces dwindling droppings needs a veterinarian the same day. Logging the measured pellets, greens rotation, and monthly weight for your Rex rabbit in KinsLe's Care Teams means the person feeding sees the plan rather than guessing at the scoop.
