Mini Rex Rabbit

Oryctolagus cuniculus (domestic rabbit)

The Mini Rex is not simply a small version of the original French Rex breed — it descends from a separate, later American breeding effort that deliberately combined the rex coat mutation with a smaller frame, and it carries its own ARBA standard, color range, and show history distinct from the larger Rex. The defining rex-coat gene is shared with the standard Rex (it shortens the coat's longer guard hairs to match the plush undercoat, giving the famous dense, upright velvet texture down to the footpads), but a lighter body carrying that same coat mutation changes some of the day-to-day care emphasis compared to the heavier standard breed. General rabbit digestive and dental biology — the need for near-continuous hay intake, molar wear, gut motility, and GI stasis risk — is identical across every domestic rabbit breed and is covered in depth in this site's GI stasis guide rather than repeated here. What genuinely sets the Mini Rex apart from the original Rex, beyond raw size, is the show and pet-trade history behind it: Berry's program deliberately selected for the smaller frame while retaining ARBA's full recognized color range, and the breed quickly became one of the most popular rex-coated rabbits in North America specifically because its smaller size suits apartment and indoor-only households better than the larger standard Rex does.

Husbandry

Enclosure size

A minimum 8-10 sq ft footprint suits one adult comfortably — noticeably less than a full-size Rex requires, tracking the breed's lighter build — with time outside the enclosure every day still essential regardless of the smaller footprint

Temperature gradient

Keep the room steady in the 60-75°F (15-24°C) band year-round; overheating is the bigger danger of the two extremes for any rabbit, since the species has essentially no working panting or sweating mechanism, and the velvet coat's density buys this breed nothing on that front

Diet

Unlimited grass hay as roughly 80% of intake, a measured pellet portion scaled to this breed's smaller adult weight, and daily fresh leafy greens — see the GI stasis guide for full digestive detail

Cohabitation

Bonding with a second rabbit is generally the better long-term arrangement for this genuinely social species, best attempted in a slow, staged process on ground unfamiliar to both animals; breeders frequently point to the Mini Rex's easygoing average temperament as an asset in that process, though no pairing should skip a properly monitored introduction period on that reputation alone

Substrate

A fully solid floor is the only acceptable base — wire mesh is a firm no — cushioned in resting spots with towels or a soft mat, because the rex-coat mutation that gives this breed its texture strips away a layer of natural cushioning at the feet that a normally coated rabbit still has

Handling

A Mini Rex is genuinely easier to lift securely than its full-size counterpart simply by virtue of being lighter, though the core technique doesn't change: a keeper needs both hands committed, cradling the front end while fully bracing the rear, because a rabbit that kicks out against an unbraced hindquarters can hurt its own back regardless of how small the animal is. The breed has a reputation among owners and breeders for a calm, people-oriented temperament, and its smaller size combined with that even disposition has made it a popular choice for households wanting a rabbit that's genuinely manageable to handle day to day — though, as with any rabbit, individual personality varies and a specific animal's body language should always take precedence over the breed's general reputation. The plush coat itself needs surprisingly little grooming intervention: unlike a longer-haired rabbit, over-brushing a rex coat can actually flatten and damage its upright nap, so a light hand and infrequent, gentle grooming preserves the texture better than a regular brushing routine would. A monthly nail trim and a quick weekly hands-on check of the hocks, ears, and teeth alignment covers this breed's routine maintenance beyond feeding, and because the smaller frame can still mask a slow weight change, tracking actual body weight periodically catches a developing problem earlier than a visual glance would.

Signs of good health

• No redness, bald patches, or a hardened callus forming on either hock — a specific check this coat-linked breed calls for that most other rabbit breeds don't need as urgently
• A coat that keeps its dense, upright plush texture without patchy thinning or flat, matted areas
• Steady output of round, dry fecal pellets throughout the day with no multi-hour gap
• Weight holding steady within the breed's smaller normal range via actual hands-on weighing
• A level, weight-bearing stance on all four feet, without favoring one side in a way that might point to foot discomfort
• Dry, unblemished nostrils and bright eyes, with none of the paw-inner crusting that comes from a rabbit repeatedly wiping a runny nose
