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.
