Plants, cupboards and household physics to sort before kitten day.

A kitten is a toddler that can jump five times its height and fit behind the washing machine, so an hour of preparation before collection day saves genuine drama. This is the room by room sweep we recommend to every family, learned from a house that has raised many litters of professional troublemakers.
Kitten proofing begins on your hands and knees, because the hazards live at their altitude, not yours: charging cables and earbuds that read as chewy snakes, hair bands, buttons and bread bag clips sized perfectly for swallowing, houseplant leaves within lunge range, and the looped cords of window blinds, which deserve special mention as a genuine strangulation risk and should be cleated up high, every one.
Do the crawl in every room the kitten will access, and repeat it after any redecoration or new gadget, because hazard maps go stale. Ten minutes at floor level is the cheapest safety equipment ever invented.
Every home should know the short list by heart: lilies above everything, so dangerous to cats that pollen groomed off fur can cause kidney failure, meaning the only safe lily in a cat house is none; antifreeze, lethally sweet tasting, wiped up to the last drop and stored sealed; human medicines, with painkillers the headline; and concentrated cleaning products locked behind a childproof latch.
Add the seasonal supplements, festive plants and chocolate in winter, permethrin dog flea products year round, and the rule that covers the gaps: anything you would keep from a toddler, keep from a kitten, in a cupboard that actually closes.
Kittens treat height as a rumour and gaps as invitations, so the exit audit is non negotiable: upstairs windows opened only with secure screens or limiters, because cats do fall and the folklore about always landing well is paid for in veterinary bills; tilt opening windows flagged specifically, since the tapering gap can trap a climbing cat with awful results; and balconies treated as open windows with furniture.
Ground floor doors get a household protocol during the settling weeks, one door at a time, checked before opening wide, and every visitor briefed. The kitten only needs to be lucky once to be out; the household needs to be consistent always.
Thread, ribbon, wool, tinsel, hair ties, blind cords and dangling phone cables form a single hazard family: linear objects that kittens cannot resist and cannot safely swallow. A swallowed length can gather the intestine like a drawstring, one of feline medicine’s true emergencies.
Proofing means elevation and eradication: sewing kits boxed, blind cords cleated high, ribbons binned after wrapping, hair ties treated like loose change near a toddler. And the iron rule: never pull a visible thread from either end of a kitten, mouth or otherwise; that is the vet’s job, immediately.
Kittens seek warmth and enclosure, which makes appliances a lethal lottery: washing machines and tumble dryers with doors ajar, dishwashers mid load, reclining chairs and sofa beds with kitten sized voids in their mechanisms. The accidents are rare and uniformly terrible.
The countermeasures are pure habit: appliance doors kept shut, a bang on the machine and a headcount before every cycle, recliners operated only when the kitten is visible. Households that adopt the drum check in week one keep it for life, which is exactly the point.
Bathrooms concentrate risk in a few square metres: toilet lids left up are a drowning hazard for tiny kittens, razors and cotton buds sit at paw height, medicine cabinets hang open, and cleaning products live under the sink behind doors a determined paw can swing.
The audit takes five minutes: lids down as house policy, sharps and swallowables into closed cabinets, child latches on the chemical cupboard, and hot straighteners or curling tongs never left cooling where a cat can land. Small room, biggest habit density in the house.
Half of kitten proofing is briefing the household: doors closed means checked first, because kittens teleport into wardrobes and airing cupboards; feet shuffle rather than stride for the first weeks; guests are told about the door dash risk before it happens, not after.
Put the poison list on the fridge, lilies, paracetamol, ibuprofen, antifreeze, and the vet’s number beside it. Rules written down get followed by visitors, children and tired adults alike, and the kitten is protected by the whole team rather than the most careful member.
Kitten proofing is crawling your home at kitten height and thinking like a curious burglar: cables, cords, gaps, poisons, dangling temptations and small swallowables all managed before arrival day. The classics cause most emergencies, lilies, human medicines, string and open windows, and thirty minutes of preparation prevents nearly all of them.
Lilies are catastrophically so, every part, even pollen groomed off fur, and several common plants cause lesser harm. Audit against a reliable toxic plant list and rehome the failures; the kitten will taste test eventually.
Young teeth find cables irresistible: sheathe the reachable ones, unplug the idle ones, and offer legal chewing alternatives during teething. A bitter deterrent spray adds a second line where sheathing is impractical.
Locking restrictors that limit openings to a few centimetres, plus screens on favourites, keep air moving and kittens inside. Tilt and turn windows need special attention; the tilt gap can trap a climbing cat.
Adolescence retires some risks and keeps others: string, lilies, human medicines and open drums stay dangerous for life. Think of proofing as graduating from total lockdown to permanent good habits.
The poison trio: lilies out of the house, human painkillers locked away, antifreeze stored sealed and spills cleaned instantly. Everything else on the list injures; these three kill.
Lilies are the one to say out loud: every part of the plant, even the pollen, can cause fatal kidney failure in cats, so lilies simply do not enter a cat household. Check other houseplants against a reliable toxic plant list before kitten day. Second, washing machines and tumble dryers, which read as perfect caves, so doors stay shut and drums get checked every single time. Third, windows above ground level and balconies, which need restrictors or mesh, because kittens have no fear and imperfect judgement. Fourth, the medicine and cleaning cupboards, which stay closed, with the reasons spelled out in our health basics guide.
Cables get tucked away or sleeved in protectors, especially charger cables at pouncing height. Hair bands, string, ribbon, tinsel and dental floss are swallowing hazards that can require surgery, so they live in drawers now. Small toys with parts that detach, needles and thread, and rubber bands join them. Blind cords get cloud hooks or cleats, because a loop at kitten height is a trap.
The kitchen wants a lids on, hobs guarded, bin closed policy. The bathroom keeps the toilet lid down and razors out of reach. The garage is generally off limits entirely, since antifreeze tastes sweet to animals and tiny amounts are lethal. And everywhere, get low: crouch to kitten height in each room and look for the gap behind the sofa, the hole under the units, the space behind the bookcase, then block what you find.
Proofing works best alongside provision: a scratcher where the sofa corner tempts, toys where the cables were, a step up to the sofa instead of claws up the fabric. The Cat Shop exists for exactly this handover, and the safe room setup for the first days is covered step by step in our settling in guide.
