Rex rabbit housing ventilation advice

Before anything else — most rabbit hutches sold in pet shops are far too small. Rabbits need room for at least three full hops, the ability to stand completely upright, and separate zones for sleeping and toileting. That's a baseline, not a luxury. Now, Rex rabbits have a particular vulnerability worth flagging early: their dense, velvet-like coat means they lose heat less efficiently than other breeds, so ventilation and positioning aren't just nice-to-haves — they're genuinely important for welfare. Are you planning to house your Rex indoors or outdoors, how many rabbits do you have, and what sort of space are you working with?

That's a good amount of space — more than enough to set him up properly. For a Rex outdoors, the two things I'd prioritise above everything else are shade and airflow. You want a hutch that never sits in direct sun during the hottest part of the day, and one with solid mesh panels rather than solid wood sides, so air can actually move through. Solid-sided hutches trap heat badly in summer. Can I ask — are you looking at a hutch-only setup, or are you thinking about a hutch with an attached run?

Good instinct — that's the right approach. For a Rex specifically, I'd point you toward the Outback Double Hutch with Run by Pets Imperial. It's a solid two-storey hutch with a good-sized attached run, and crucially it has large mesh panels on the front and sides that allow proper cross-ventilation rather than just a small door opening. The upper sleeping area is sheltered but not sealed, which matters on warm days. Position it so the mesh faces away from direct afternoon sun — ideally backed against a fence or wall that provides natural shade from the west — and add a ceramic floor tile inside in summer as a cool surface for him to lie on. That combination handles Rex heat sensitivity better than most hutch setups I've seen.

Rex are medium to large rabbits — typically 3.5 to 4.5 kg — so size absolutely matters. The Outback Double is 5 feet wide, which clears the three-hop minimum for a rabbit of that size, and the run extension adds meaningful floor space for daytime movement. The upper deck gives him a retreat area separate from where he'll eat and toilet, which is what you want behaviourally. It's not a starter hutch — it's a genuinely usable size for the breed.

In winter the concern flips — you're protecting against cold and damp rather than heat. Cover the mesh panels with a breathable hutch cover or secure a piece of hessian sacking over them at night to cut wind chill, but never use plastic sheeting that seals all airflow. Rex coats, despite being dense, don't insulate quite as well as longer-haired breeds, so a thick layer of straw in the sleeping compartment is important. Position the hutch so the back faces the prevailing wind direction if you can. The ventilation you built in for summer is still there — you're just moderating it rather than removing it.
