Mini Rex

The Mini Rex is the velvet rabbit: a 4.5-pound breed with a plush coat that people cannot stop stroking, and ARBA says it is consistently the number one or two entry at any ARBA Convention. Day to day it is a standard, sociable house rabbit that thrives on floor time, hay and a settled routine.

Size
Maximum 4.5 lb (ARBA); Merck's small class is 2–6 lb

Lifespan
7–14 years (House Rabbit Society); 8–12 years typical (RSPCA)

Daily attention
Daily hay, greens, water, litter scoop, bottom check; at least four hours out of the pen daily (House Rabbit Society) that can overlap your evening; weekly brush plus teeth and nail check

Sound level
Low; quiet compared with dogs and cats

Housing
Pen or free-roam room on soft or solid flooring. Merck's 18 x 24 in small-breed cage is a base only; RSPCA recommends no smaller than 3 m x 2 m x 1 m for a pair

Coat
Short, dense plush (rex) coat; sheds about every three months like other rabbits

Energy
Moderate to high; most active at dawn and dusk

Group
ARBA-recognized since 1988; small breed

Temperament

ARBA records that the Mini Rex was developed in Texas in 1984 by Monna Berryhill, recognized in 1988, and appeals to both new and seasoned breeders. None of the fetched registry or veterinary pages describes a Mini Rex temperament, so what follows applies to rabbits generally. Merck says rabbits are usually quiet, social and playful when treated gently, but not all like to be held, and they are most active at dawn and dusk. The House Rabbit Society describes rabbits as inquisitive yet cautious, skittish yet confident, energetic yet lazy, and says being held and cuddled is one of the most common misconceptions people have about them; most prefer to keep their feet on the ground. They are intelligent and constantly looking for activity, which is why chewing and digging show up when they are bored. Merck's size note applies: smaller rabbits are more delicate and need especially careful handling.

Daily needs and attention

The daily routine is the same as any small house rabbit and fits around a job because rabbits are up at the ends of the day. Merck says they are most active at dawn and dusk; LafeberVet says they can adjust somewhat to the family's schedule. Every day: unlimited grass hay, which LafeberVet says should make up the bulk of the adult diet, fresh vegetables at about 25% of the diet, a small pellet ration (VCA suggests a quarter cup per 5 pounds of body weight), clean water and a scooped litter box. The RSPCA wants a daily look at the bottom and tail area and a weekly check of front teeth and nails. Exercise is the big commitment: the House Rabbit Society sets it at least four hours a day or thirty hours a week, which is time out of the pen rather than time you spend entertaining the rabbit. Merck adds nail trims every one to two months.

Health and lifespan

The House Rabbit Society gives 7 to 14 years and the RSPCA 8 to 12. No fetched source names a Mini Rex-specific disease; the risks below are general. Feet deserve attention because the rex coat is short: VCA says rabbits housed on a hard surface or wire flooring may get pressure sores or abrasions on the hock, and Merck says treatment includes soft bedding and solid resting surfaces. GI stasis, the slowing of food through the gut, can become life-threatening in hours per VCA; Merck lists no droppings for more than 12 hours as a warning sign. Dental disease follows a low-fiber diet, since Merck says rabbit teeth continue growing throughout life; VCA recommends free-choice grass hay and a small daily pellet ration. Unspayed females have an 85% chance of reproductive cancer per the House Rabbit Society, and Merck calls uterine cancer common and often fatal after age 3. Merck advises an exam on arrival and yearly, plus the RHDV-2 vaccine.

Habits and behavior

These are rabbit habits, not Mini Rex habits; no breed-specific behavior data exists in the fetched sources. Chewing is a completely normal, natural and necessary activity that rabbits find highly enjoyable, per the House Rabbit Society, and destructive chewing or digging can be diverted into healthy projects. Rabbits instinctively choose a corner for urine and most droppings, so litter training generally works; the House Rabbit Society says they like to munch while they potty, so hay goes next to the box, and spaying or neutering improves habits. They will never be 100% tidy. Unneutered males spray. Body language is readable once you know it: a nose nudge to your shin means you are in the way, a flop onto one side means contentment, and ears back means they dislike what you are about to do. Rabbits are highly social, playful and inquisitive animals per the RSPCA, and LafeberVet notes they are territorial with a strong hierarchy.

Housing: pen, free-roam room or hutch

Flooring is the Mini Rex-relevant detail; the rest is standard. Merck's minimum cage for small breeds is 18 x 24 inches, and Merck notes wire flooring keeps a cage cleaner but rabbits also need a smooth resting area on the cage bottom; VCA links hard or wire floors to hock sores. LafeberVet asks for solid flooring. In practice the answer is a metal-wire exercise pen, which the House Rabbit Society calls by far the most popular rabbit housing of recent years, on vinyl, a chair mat or a rug, expanded upward with ramps or step-ups to multiple levels. The RSPCA's benchmark for two medium rabbits is a living space no smaller than 3 m x 2 m and 1 m high, which rules out a hutch as the whole home. Free-roam in a bunny-proofed room, with the pen left open as home base, is the other realistic setup. Keep it indoors; Merck warns that long exposure above 80°F can make rabbits sick.

Challenges

Things to plan for. Chewing: the House Rabbit Society names destructiveness as the number-one reason rabbits are surrendered, so cords, baseboards and rugs need protection before the rabbit arrives, and cardboard and untreated wood should be on hand. Feet: keep the rabbit off wire and hard bare floors so hock sores never start. Cost: the same guide says veterinary care for rabbits, categorized under exotics, can be quite expensive, and the RSPCA suggests pet insurance. Handling: Merck says smaller rabbits need especially careful handling and that you should always support the hind end and back legs when lifting. Company: the RSPCA says rabbits can develop abnormal behavior and may suffer if left alone with nothing to do for long periods, so a household that is out all day should plan on a bonded pair or a lot of enrichment. Lifespan: 7 to 14 years is longer than many people expect from a small pet.

The fun part

The coat is the obvious pleasure, but the behavior is better. The RSPCA describes the binky, the leap-twist a rabbit does midair, as a sign of a very happy rabbit, and the House Rabbit Society's guide catalogs the rest: a dash across the room with a 180-degree turn in midair, a flop onto one side after grooming, soft tooth grinding that means I am very happy, running circles around your feet. Rabbits toss, bat and shake jingle toys, dig through cardboard packed with paper, and tunnel through concrete-form tubes; the RSPCA suggests a toilet-paper tube stuffed with hay as a puzzle feeder. The House Rabbit Society's honest guide says rabbits may enjoy sitting beside you, gently nudging you with their nose, or even hopping onto your lap, and the RSPCA notes pet rabbits can be taught to respond to commands with reward-based training. This is general rabbit behavior; the Mini Rex just does it in velvet.

“Jingle-rattle toys are tossed, batted, and shaken.”

Living with kids and other pets

The soft coat invites petting, and petting on the floor is fine; picking up is the problem. The House Rabbit Society says rabbits often are not the best match for very young children under 7, that picking up a rabbit can frighten it and injure both child and rabbit, and that only adults should lift the rabbit when necessary. The rabbit's well-being will rest on the adult's shoulders, and the same source says it is common for children to lose interest or struggle with consistent care. Cats: indoor house cats typically coexist peacefully with rabbits given proper introductions and supervision, though cat claws and mouths carry bacteria and a playful swat can cause a serious abscess. Dogs: low prey drive is required, introductions happen with the dog lying down on leash, and never allow the dog to chase the rabbit, even in play. Another altered rabbit is often the best companion; Merck notes opposite-sex pairs will breed unless spayed or neutered.

What to ask the rescue

Is the rabbit spayed or neutered? Is it litter trained, and in what kind of setup? What flooring has it lived on, and have its hind feet been checked for sore spots? Is it eating mostly hay and at a healthy weight? How does it behave when approached on the floor, and how does it handle being lifted for nail trims? Has it lived with cats, dogs or another rabbit, and is it part of a bonded pair? Because the Mini Rex is bred and shown in large numbers, ask where this one came from and how much handling it has had. The House Rabbit Society suggests not fixing on breed, size or age, letting adoption counselors trained in evaluating dispositions match a rabbit to your household, and considering a bonded pair, since two rabbits are no more bother than one and keep each other company while you are away. The RSPCA favors a neutered male with a neutered female.

“Pay attention to the personality descriptions listed by the adoption counselors, who have been trained in evaluating dispositions and matching them with compatible families.”
