Overview
- The Mini Rex carries the recessive rex gene, which shortens the guard hairs to the level of the dense undercoat and produces a plush, velvet-like coat standing about 5/8 in (1.5 cm) deep.
- Monna Berryhill developed the breed in Texas in 1984 by crossing a Dwarf Rex buck with a small standard Rex doe, the ARBA recognized it in 1988, and it has ranked among the most popular pet and show rabbits in the United States ever since.
- At 3-4.5 lb (1.4-2 kg) a Mini Rex sits between the tiny Netherland Dwarf and mid-sized breeds like the Dutch, with a normal muzzle rather than the flattened face of a Holland Lop.
- It is still a full rabbit commitment of 8-12 years.
- The welfare standard is a neutered, bonded pair with generous permanent space and daily exercise, never a lone rabbit in a hutch.
Housing
- Give a bonded pair a permanent enclosure of at least 3 m x 2 m and 1 m high (roughly 10 x 6 ft, 60 sq ft), accessible day and night, plus supervised free-roam time in a rabbit-proofed area, as a shop-bought hutch on its own is not enough.
- Flooring matters more for this breed than for most rabbits: the short rex coat leaves the footpads almost unpadded, so wire floors are ruled out entirely and hard surfaces should be covered with mats, fleece, rugs, or deep bedding.
- House them indoors or in a fully predator-proof, weatherproof shelter away from damp and draughts.
- Rabbits tolerate cold far better than heat, so avoid sustained temperatures above about 77°F (25°C).
- Add hides, tunnels, platforms, digging boxes, and a litter tray, which most Mini Rex learn to use quickly once neutered.
Diet
- Unlimited grass hay such as Timothy should make up at least 85% of the diet, wearing down the continuously growing teeth and keeping the gut moving.
- Add a daily portion of varied leafy greens and a small measured ration of plain pellets, about an eggcup or one tablespoon per kilogram of body weight per rabbit, with fresh water always available, ideally from a bowl.
- Avoid muesli mixes, sugary treats, and more than occasional fruit, which drive selective feeding, obesity, and dental disease.
- Extra weight is doubly harmful in a Mini Rex because it presses the thinly furred hocks into the floor.
- Introduce any diet change gradually to protect the sensitive gut from stasis.
Health
- Sore hocks (pododermatitis) is this breed's signature risk: rex fur leaves the feet with little protective padding, so check the hocks weekly for thinning fur, redness, or scabs and improve the flooring at the first sign.
- Obesity, overgrown nails, damp bedding, and dirty litter all make hock sores dramatically worse.
- Gut stasis is a life-threatening emergency whenever a rabbit stops eating or passing droppings and needs same-day veterinary care.
- Vaccinate against RHDV2 (in the UK and Europe also against myxomatosis and RHDV1, where those vaccines exist), neuter to prevent uterine cancer in does and ease bonding, and register with a rabbit-experienced vet early for annual dental and weight checks.
- The velvet coat itself needs almost no brushing, and stiff brushes can damage it.
- Strip loose fur during moults with damp hands or a soft grooming mitt instead.
Temperament
- Mini Rex are generally calm, tolerant, and people-oriented, closer in temperament to the steady Dutch than to the more reactive Netherland Dwarf, though youngsters can be lively.
- Like all rabbits they are prey animals that prefer four feet on the ground and dislike being picked up and carried.
- The velvety coat invites constant stroking, and many Mini Rex genuinely enjoy long floor-level petting sessions, which suits gentle, seated interaction better than a child's lap.
- They are social animals and should live with a neutered, bonded companion, as neutering also improves litter habits and pairing success.
A good fit for
- Keepers wanting a calm, low-grooming small breed
- Households happy to interact at floor level
- Owners committed to a neutered, bonded pair
- Homes offering soft-floored free-roam space
Common mistakes to avoid
- Wire or bare hard floors causing sore hocks
- Over-brushing the delicate rex coat
- Obesity adding pressure to thinly furred hocks
- Keeping a single rabbit or hutch-only housing
- Skipping RHDV2 vaccination and neutering
Is your enclosure big enough?
Is this urgent?
A rabbit that stops eating is an emergency, not a wait-and-see. Nothing else on this page is as time-critical.

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 mini 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.
Never (23)
Rare treats (13)
Occasional (18)
Everyday foods (9)
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.
What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
