🏠Housing a Rex: a 4 m² pen and its layout

Rex : Flooring is the critical point: never wire or slatted floors; use thick mats, covered foam tiles or deep, soft bedding instead. Every resting spot should be padded.

In short: Between 3 and 4.5 kg as an adult, short and dense velvety fur, calm and affectionate temperament. A medium-sized rabbit, calm and people-oriented, that enjoys contact and ground-level play. The sparse fur under its feet rules out wire or slatted floors: thick mats and padded resting spots are the priority purchase.

How much space for a Rex?

For its 3 to 4.5 kg, plan a permanent pen of at least 4 m² — the shop “rabbit cage” is only an annexe (litter, hay), never a habitat. Modular 80 cm panels do the job for most individuals, the goal remaining open-door free-roaming.

Fitting out base camp

Underfoot, rugs or low-pile carpet come first: a Rex’s feet were not made for skating on parquet — doubly important for the rex’s sensitive feet, completed by a plant-litter tray with the hay rack right above it (the pairing works: rabbits nibble as they go), one hideout per occupant and a tip-proof ceramic bowl.

Temperature and location

Remember the 26°C threshold: above it, the Rex needs airflow and cooling (a wrapped frozen bottle) — and its pen permanently avoids both direct sun and draughts. A calm corner of the living room, where the Rex watches family life without being underfoot, is the ideal spot.

Frequently asked questions

What pen size for a Rex?

A permanent 4 m² minimum for an adult of 3 to 4.5 kg, plus daily free time — the shop cage serves only as a litter-and-hay annexe.

Can a Rex live outdoors?

Yes, with an insulated frost-free hutch, a predator-proof run (buried mesh, a roof) and summer shade — but indoor free-roaming remains the safest setup.
