Quarantine Bedding: What a Cattery Does for a New Cat

Short answer: quarantine bedding is cheap, disposable and boring. A new cat gets bedding that can be washed hot or binned without grief, nothing shared with other pets, and familiar scent moved across on a clean cloth. Each piece is chosen for how it leaves the room, not how it looks.

Eleven years of running a boarding cattery in Sydney taught me that a quarantine pen is planned before the cat arrives, not after. One pen stayed permanently empty, stripped to the frame, and the bedding trolley was stocked separately: single-use liners, towels on their last legs, two washable mats and a stack of cheap face washers. New arrivals, cats on treatment drops, any cat that sneezed twice in the night, they all went in there. Their bedding never crossed into the general laundry until the period ended. What surprised new owners most was how little I spent on it. Quarantine bedding is not about comfort first. It is about what happens to it afterwards.

Why bedding never leaves the pen

In a boarding setup, bedding sits on the same checklist as bowls and litter scoops. A cat in isolation gets its own set, and none of it mixes with the general pool until the period is over. The reason is mechanical rather than dramatic. Fur, dander and moisture settle into fabric, and fabric carries them further than most people expect. A mat resting on top of a washing basket can seed a whole laundry shelf. So the rule was absolute: bedding goes into the pen and comes out either into a hot wash or into a lined bin, never onto a bench or a chair in between. At home the same logic applies. If your new cat is isolated in a spare room, that room's soft furnishings belong to that cat alone. Do not carry their blanket out to the lounge for the family to pat.

What got used and tossed

The toss pile did most of the work. Newspaper went down under everything as a catch-all layer and came off daily, rolled and binned. Cardboard boxes cut low made beds and scratch surfaces in one, and when a box was soaked or shredded it went out whole. Cheap fleece offcuts, the kind sold as remnants for a few dollars, sat on top for warmth, and if a cat had loose stools or a burst of sneezing on them, they were binned rather than washed. Old towels earned the same treatment once they reached rag stage. The trick was cost. Nothing in that pen carried any value, so nobody hesitated at the bin, and a couple of dollars of liner was always cheaper than an afternoon of scrubbing. Owners can copy this at home: a stack of old bath towels, a few remnant fleece pieces, and a lined bin beside the door.

What was worth washing

Washable bedding earned its place by surviving hot cycles. Vet fleece and dense polar fleece mats were the backbone, because they dry fast, shed fur well and hold up to a 60 degree wash, which is the temperature I ran for anything out of a quarantine pen. Two mats per cat minimum, so one was always drying while the other was in use. Thick plush beds came last, because they hold moisture in the base and dry slowly, and a damp bed in a warm room is worse than no bed at all. Everything went through the machine as its own load, then the machine ran hot and empty afterwards, and the door seal and filter got wiped. If you are buying for this period, browse the washable cat beds available and read the care label first. A bed that wants a cold gentle cycle is the wrong bed for quarantine.

• One cat, one set of bedding, nothing shared for the whole quarantine period.
• Bin cheap liners and ruined towels instead of washing them.
• Keep two washable mats per cat so one is always drying.
• Wash quarantine bedding at 60 degrees, separately, then wipe the machine seal.
• Move scent between rooms with a clean cloth, never with shared bedding.

Handling scent across the door

A new cat cannot be near the others, but the others can still be introduced by nose. Cloth swapping was standard practice in the cattery and costs nothing at home. Take a clean washer, rub it gently along the new cat's cheeks and chin, then take a second washer and do the same to your resident cat. Swap them, and let each cat investigate the other's scent at their own pace. Feed the resident cat on the far side of the isolation door while the new cat eats on theirs, so the two smells get filed together as meal smells. What I avoided was swapping the bedding itself in the early days. Bedding carries a heavier scent load, and pulling a cat's bed out from under them mid-quarantine unsettles the very cat you are trying to settle. Washers are small and replaceable. Beds are territory.

Setting up a spare room properly

At home, isolation usually means a spare bedroom or a bathroom, and the bedding follows the room. Hard flooring suits the disposable route: a cardboard box lined with an old towel, replaced as needed, plus one proper washable mat in the quietest corner away from the litter tray. Cats in a new place tend to pick one spot and commit to it, so put the good mat where you want them to settle, usually with a wall behind it and no direct sightline to the door. Keep bedding flat or shallow. Deep plush beds hide mess, and during quarantine hidden mess is exactly what you need to see. Check the bedding at each feed rather than doing one big daily clean. Small, frequent swaps keep the room fresher and give you a daily read on appetite, litter habits and mood.

When the quarantine period ends

How long isolation lasts is a question for your vet, and I never guessed at it. In the cattery the ending was always the same, whatever period had been set. Bedding went first: a final hot wash of everything the cat had touched, while the cat itself was settled into a cleaned carrier. Then the pen was stripped, scrubbed and left to dry properly before its next resident. At home the same sequence works. Wash or bin everything, clean the room, and only then open the door. Do not carry the old quarantine bedding out into the living areas as the ongoing bed. Let the post-quarantine bed be a fresh start, sited where you actually want the cat to sleep long term. The old bedding did its job, and it can retire.
