The small cage sold as a rabbit home asks an athletic, intelligent animal to live in a space she can cross in two hops. The better indoor answer starts from her body instead: she needs to stretch out completely, rear up, move at speed, hide, graze, and choose where to be, and the setup that allows all of that looks like territory rather than furniture.
A Pen or a Proofed Corner, Not a Small Cage
Choose a large pen or a rabbit-proofed room corner rather than a small cage. A pen built from modular panels can wrap a corner, run along a wall, or enclose most of a spare room, and a proofed corner gives her a defined territory inside a room the family uses. Floor the area with something non-slip and cleanable, because rabbits get poor grip on smooth boards and can injure themselves scrambling, and protect every cable within reach with covers or by lifting cables out of the territory entirely. Baseboards, furniture legs, and door edges inside the pen will be chewed, so accept sacrificial cardboard and wooden chew pieces as the planned alternative she is meant to work on.
Height matters less than footprint, but the pen must still contain a rabbit who stands to investigate, and the door or gate should let you enter for cleaning and social time without dismantling the setup each day.
The Home Base Inside the Territory
Inside the pen, build a home base holding unlimited hay beside a roomy litter tray, fresh water in a heavy bowl, a hideaway, and space to stretch fully, stand, and take several hops. Hay beside the tray works because rabbits graze and toilet at the same time, so the arrangement encourages good litter habits while keeping the main food where she spends her resting hours. A heavy bowl resists tipping better than a bottle for many rabbits and lets her drink in a natural position, refreshed daily and checked whenever you pass. The hideaway, a house or a sturdy box with an entrance she fits through easily, gives her the retreat every prey animal needs, a place where she is never dragged out and can feel the day is hers to leave.
That home base is her secure address even when the wider room is open to her. She will eat there, nap there, and run back there when a noise startles her, and keeping its layout stable while the wider room changes gives her one constant in a busy house.
Life Beyond the Pen, Where the Family Is
Litter habits reward the setup rather than training sessions. Rabbits typically choose one corner for toileting, so place the roomy tray in the corner she picks instead of the corner you picked, line it with paper-based litter, and keep the hay rack or a hay pile directly beside or above it so grazing and toileting happen together. Move stray droppings into the tray during the first weeks, clean the tray often without scrubbing away every trace of her scent from it, and the home base usually stays the tidy center the rest of the room depends on.
Daily exercise beyond the pen in the proofed room completes the setup, because even a generous pen cannot offer a full sprint or a long exploring circuit. Rabbit-proof the room as you did the pen, supervise the session, and let her choose her routes between furniture, tunnels, and boxes. Site the whole arrangement where the family actually spends time rather than in an unused room, since rabbits are social animals who bond through proximity, and a rabbit housed where life happens is handled, noticed, and checked far more than one shut away alone. In a shared home, pen cleaning, hay refills, water checks, and exercise sessions rotate between people, and keeping those jobs and her layout notes in one place everyone reads is how Family Sharing supports rabbit keepers on KinsLe.
