Walk the room at ankle height first
Sit on the floor and look at your room the way a rabbit, guinea pig, or free-roaming rat will meet it. From there the hazards line up: charger cables dangling at chew height, a gap under the wardrobe wide enough for a whole animal, skirting boards with a tempting painted edge, a bed base a pet can vanish into, and cleaning sprays stored at floor level. Student rooms concentrate all of this in one small space, because the pet's home, your desk, your bed, and your storage are all the same few square metres.
List what you find before you fix anything. Working through a list stops the common pattern of proofing the obvious cable and missing the gap behind the bed.
Cables, gaps, and chewable fixtures
Cables are the urgent job. A rabbit or rat can cut through a phone charger in seconds, and a mains cable is dangerous to the animal as well as to your deposit. Run cables inside split trunking, lift them onto wall hooks above reach, or route them behind furniture pushed flush to the wall so there is no explorable channel behind it. Never rely on a pet being uninterested; chewing starts the week you stop watching.
Block gaps with solid boards, mesh panels, or storage boxes that fill the space completely. A pile of soft items is a tunnel waiting to be dug. Protect skirting and door edges in the floor-time area with clear guards or furniture placement, because a landlord will charge for chewed woodwork and the chewing happens quietly, usually at night.
Protecting floors, walls, and your deposit
Stand the enclosure on a large washable mat or a sheet of vinyl offcut that extends beyond its edges, catching kicked bedding, hay, and the inevitable water-bottle drip before they reach rented carpet. Under a litter or hay area, add a second smaller mat you can shake and wash weekly. Photograph the floor, skirting, and walls around the pet area before the animal arrives, and keep those pictures; condition disputes are much simpler with dated evidence of how the room started.
Choose an enclosure position that is not against a damp outside wall and not over the only route to the door, so a hay-heavy clean-out does not mean carrying waste across your bed.
Poisons, plants, and other people's habits
Move cleaning products, laundry pods, medicines, and cosmetics into a closed cupboard or a lidded box the pet cannot open; free-roam accidents usually involve something left on the floor after use. Check every houseplant in the room and move any you cannot confidently identify as safe for the species out of reach or out of the room.
Then proof the humans. Flatmates leave doors open, offer unsuitable snacks, and bring guests who pick animals up. Agree three house rules and put them where visitors see them: the door stays shut during floor time, nobody feeds the pet except from its own food box, and nobody lifts the pet without the owner present. Short, friendly, and written beats a long talk after something has gone wrong.
