Build the Pen Around Rex Feet and That Velvet Coat
A Rex rabbit should come home to a pen whose floor is finished before she steps onto it. Add a large hide, a hay-filled litter tray, a spill-proof water bowl, and a clear corner for stretching out, because a Rex is a medium, athletic rabbit who needs room to turn, dig at a mat, and flop fully sideways.
Open the carrier inside the pen and let her walk out onto that soft surface at her own pace. Resist the urge to stroke the famous coat straight away. A Rex who is allowed to sniff, chin-mark the hide, and eat hay undisturbed on arrival learns the pen is hers, and handling offered after that choice goes far better than handling imposed at the door.
Reading a Rex in the First Few Days
A settling Rex rabbit often looks bolder than a tiny dwarf breed, exploring sooner and investigating people with her whiskers forward. Treat that curiosity as an invitation to sit nearby, not as consent to be scooped up. Rex rabbits are strong kickers with fine skin under thin fur, and a rabbit who twists during a lift can scratch herself or be dropped.
Watch her gait on the new flooring each day. A Rex who shifts weight off a hind foot, sits hunched on her hocks, or leaves a pink, hairless patch visible on the heel is telling you the surface or her weight needs attention.
Keep the Diet Steady While Everything Else Is New
Feed a newly adopted Rex exactly what she was eating, even if you plan a better diet later. Unlimited grass hay does most of the work for her teeth and gut, with measured pellets and, after a settled few days, leafy greens introduced one kind at a time.
Place hay in the litter tray and in a rack she can reach while sitting on soft ground, since a Rex will often refuse hay that means standing on a hard tray edge. Note her droppings for size and quantity across the first days; a steady stream of large, round droppings says the move has not upset her digestion, while a sharp drop in eating or droppings is a same-day reason to call a veterinarian.
First Room Time and Other Animals
Give a Rex rabbit room time only after the pen routine looks boring: eating on schedule, using the tray, resting stretched out in the open. Let her leave and re-enter the pen freely during these sessions so the pen stays her chosen base.
Introduce resident dogs and cats at pen distance first, rewarding calm looking and then looking away. A Rex is large enough that some cats treat her as a peer, but no early meeting should involve chasing, pawing through bars, or a dog fixing her with a hard stare at close range. End sessions early and repeat them daily; dull repetition, not one long test, is what makes a multi-pet home feel safe to a rabbit.
One Care Sheet for a Social, Active Rabbit
Record this Rex rabbit's pellet amount, hay type, flooring setup, litter routine, and the handling approach that works for her, and share it with anyone who feeds or cleans while you are out. Rex rabbits thrive on active, predictable households, but only when every person follows the same rules about treats, floor surfaces, and lifting. A short note about her favourite herbs, her active hours, and how her hocks looked this week keeps small problems visible before they become sore ones. Storing that profile in KinsLe with Family Sharing keeps this Rex's care details in front of every helper, so her routine survives busy days and different hands.
