Rex rabbit enclosure for a 4-month-old

Most rabbit hutches sold in pet shops are far too small — rabbits need enough room to do at least three full hops, stand completely upright on their back legs, and have separate areas for sleeping and toileting. A Rex is a medium-to-large breed, so getting the sizing right from the start really matters. Before I point you in the right direction, a few quick questions: are you planning to keep your rabbit indoors or outdoors, do you have just the one rabbit, and roughly how much floor space do you have available for the enclosure?

Good news — that space gives you some solid options. Rex rabbits typically reach around 3.5 to 4.5 kg fully grown, so your four-month-old has a fair bit of growing left to do. At that size they need a minimum footprint of about 120 by 60 cm just for the enclosure itself, with height enough to stand upright. Can I ask — are you thinking of a solid cage setup, or would you be open to an indoor pen that gives him more roaming room? And is he already litter trained or working on it?

That makes complete sense, and the litter training makes everything easier. For an indoor Rex at this age — one who's going to grow into a proper medium-large rabbit — I'd recommend the Savic Residence. It measures 100 by 54 cm on the base with a full 62 cm of interior height, which means he can stand fully upright comfortably now and when fully grown. It has a large front opening door so he can hop in and out freely when you let him roam, a deep plastic base that contains litter scatter, and a removable divider so you can section off a sleeping area from his toilet corner. The bar spacing is 2.3 cm, which is appropriate for a rabbit his age — he won't squeeze through and it won't catch a curious nose. It's genuinely one of the better-built indoor cages at this size without jumping to the very expensive end. You'll likely still want to give him a couple of hours of free-roaming time in the room daily, but as a home base it does the job properly.

It's one of the better ones for cleaning. The base tray pulls out completely from the wire top section, so you can dump and wipe it down without disassembling the whole thing. The plastic is smooth rather than textured, which matters — rough plastic holds odour over time. A weekly full clean plus a spot-clean every couple of days around the litter tray and you'll stay on top of it easily. One tip: line the base tray with a layer of newspaper under his bedding — it makes the weekly swap much quicker.

Ha — you'd have been back in three months frustrated that he'd outgrown it. The Savic Residence should genuinely see him through from now to adulthood without needing to upgrade. Enjoy him — Rex rabbits are brilliant characters.
