Overview
The Rex is a medium-large breed famous for its dense, plush coat, in which the guard hairs are the same length as the undercoat, giving a velvet feel.
First developed in France in the early twentieth century, it is now one of the most popular companion breeds.
Rexes are widely described as calm, confident, and people-oriented, which makes them a strong choice for keepers who want an interactive house rabbit.
Like every rabbit they are a long, social commitment best kept as a neutered, bonded pair.
Housing
Provide a secure base of at least around 3 square metres for a pair, ideally a pen, converted room, or free-roam setup, plus several hours of daily exercise in a larger space.
Small hutches are wholly insufficient for a rabbit of this size.
Flooring matters more for Rexes than most breeds: their foot pads have thinner protective fur, so hard or abrasive floors quickly cause sore hocks.
Offer soft mats, bedding, or carpeted resting areas throughout the enclosure.
Diet
Unlimited grass hay should form the vast majority of the diet, wearing down continuously growing teeth and keeping the gut moving.
Add a daily portion of leafy greens and only a small measured amount of plain pellets.
Limit fruit, carrot, and sugary treats, and keep fresh water constantly available, ideally in a bowl.
Watch body condition: Rexes are food-motivated and gain weight easily, which worsens hock pressure.
Health
Sore hocks (pododermatitis) is the breed's signature problem, so check the hind feet weekly and act on any redness or thinning fur.
Gut stasis remains the big emergency for any rabbit that stops eating or passing droppings.
Dental disease, flystrike in warm months, and obesity are the other major risks, and vaccination against myxomatosis and rabbit haemorrhagic disease is essential in many regions.
The plush coat needs only an occasional gentle groom; over-brushing can damage it.
Temperament
Rexes are consistently described as laid-back and tolerant, often happier being petted at floor level than carried, like all rabbits.
Many enjoy lounging near their keepers once trust is established.
They are intelligent and respond well to routine, litter training, and clicker-style work.
Neutering improves temperament, litter habits, and pairing success, and reduces uterine cancer in females.

Keepers wanting a calm, cuddly-natured house rabbit
A rabbit that stops eating is an emergency, not a wait-and-see. Nothing else on this page is as time-critical.
Go now
Not eating, or not producing droppingsCall an exotics vet. Some sources treat 3 to 4 hours as the point to start worrying and 12 hours as an outright emergency; do not wait to find out which camp is right for your rabbit. Gut stasis can become life-threatening within 12 to 24 hours, and every hour of delay makes it harder to reverse.
8 hours
Hunched with the belly pressed to the floorGo now. A rabbit in this posture is in significant pain.
Now
Loud teeth grindingGo now. Distinct from the soft purr of a content rabbit. This is a pain signal.
Now
Hard, bloated abdomenGo now. Do not force-feed and do not massage. Bloat may need decompression rather than gut motility drugs, and the two treatments conflict.
Now
Maggots or fly eggs near the rearGo now. Flystrike. Check the rear twice a day in warm weather, every day, for every rabbit.
Now
Cannot cope with heat — panting, wet nose, lying flat and unresponsiveMove to shade, offer a wrapped cool pack, wet the ears, and go. Rabbits cannot pant effectively to cool themselves; distress starts around 28C and rises steeply.

Two rabbits are the minimum, and a bonded pair will also tell you when something is wrong — a rabbit sitting apart from its partner is worth a second look.
This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a rex rabbit eat that?
Hay first, greens second, everything else barely at all. A rabbit fed mostly pellets and treats is a rabbit with dental disease waiting to happen.

Rare treats (13)
AppleSugar. The seeds contain a cyanogenic compound and must be removed. A thin slice, once or twice a week. Never the seeds or core.
rare treat
BananaVery high in sugar and starch, and most animals will overeat it given the chance. A slice the width of a fingernail, rarely.
rare treat
BlueberrySugar, but a small portion size makes it easy to control. One or two berries, twice a week.
rare treat
Brussels sproutsHighly gas-forming. Half a sprout, rarely.
rare treat
CarrotSold as the archetypal rabbit food and it is nothing of the kind: carrot is a root vegetable with a high sugar content. The leafy tops, by contrast, are an excellent green. A thin slice as a treat. The tops can be fed freely.
rare treat
CauliflowerOne of the most gas-forming brassicas. A very small piece, occasionally.
rare treat
GrapesVery high in sugar. Halve them, because a whole grape is a choking hazard. One halved grape, rarely.
rare treat
OrangeAcidic and sugary; can irritate the mouth and gut. A tiny segment, rarely if at all.
rare treat
PearSugar. Remove the seeds. A thin slice occasionally.
rare treat
PeasHigh in starch and sugar. The pods and leaves are better than the peas. A few pods occasionally.
rare treat
StrawberrySugar, though lower than most fruit. The leaves are actually the better part. Half a small berry, once or twice a week.
rare treat
TomatoThe ripe flesh is safe in small amounts. The leaves, stems and any green fruit contain solanine and must never be offered. A small piece of ripe flesh, occasionally. Never the plant.
rare treat
WatermelonSugar and a very high water content, which together can loosen the gut. Remove the seeds. A small cube in hot weather, rarely.

BroccoliNutritious but a notable gas producer. Leaves and stalk are better tolerated than the florets. A small floret or a piece of stalk, twice a week.
occasional
CabbageA brassica. Gas-forming in quantity, and goitrogenic with heavy long-term feeding. A small piece, once or twice a week.
occasional
CelerySafe and well liked. Cut across the stalk so the long fibres cannot catch. A short piece, cut into segments.

occasional
DillSafe in rotation. A few fronds.
occasional
Green beansSafe cooked or raw in small amounts. Gas-forming in quantity. One or two, occasionally.

occasional
ParsleyNutritious but relatively high in calcium. Fine in rotation, not as the whole green portion. A few sprigs, a few times a week.
occasional
PelletsA uniform pelleted nugget, not a muesli mix. Muesli lets a rabbit pick out the sweet bits and leave the fibre, which is how dental disease starts. An eggcup per rabbit per day, no more.
occasional
PumpkinSafe and well tolerated in small amounts. A small cube occasionally.
occasional
RocketPeppery and well tolerated in rotation. A small handful, a few times a week.
occasional
SpinachHigh in oxalates, which bind calcium and contribute to bladder sludge and stones in animals prone to them. A single small leaf, no more than once or twice a week.
occasional
WatercressNutritious, strongly flavoured, high in calcium. A small handful occasionally.

Everyday foods (9)
Bell pepperOne of the best everyday vegetables here: high in vitamin C, low in sugar, no oxalate problem. Remove the seeds and stalk. A few strips daily.
everyday food
Bramble leavesBlackberry leaves are excellent forage and rabbits take them readily. A few leaves daily.
everyday food
Carrot topsThe leaves are a proper green and much better food than the root. A handful as part of the daily greens.
everyday food
CorianderWell tolerated, aromatic, and most animals take it readily. Part of a daily mixed handful.
everyday food
Dandelion leavesOne of the best greens available, and free. Pick well away from roadsides and anywhere that may have been sprayed. A generous handful daily.
everyday food
GrassFresh growing grass is excellent. Lawn clippings are not: they ferment in the bag and cause severe gut upset. As much as they will graze. Never mown clippings.
everyday food
Grass hayShould be about 80 percent of what this animal eats, available at all times. It is what wears the teeth down and what keeps the gut moving. Unlimited, always.
everyday food
PlantainA common lawn weed and one of the better forage plants. A handful daily.
everyday food
Romaine lettuceDark leafy lettuce with real nutritional content and a good water balance. A generous handful daily as part of a mixed selection.
everyday food
That plant or food is not on our list. Do not offer it — a rabbit cannot vomit, so anything that goes in has to go all the way through. Check with an exotics vet.
A rabbit that has not eaten for 8 hours needs a vet, whatever the reason. Diet changes are the most common trigger for that, which is why new foods go in one at a time.
