Kittens get into things adult cats generally ignore, mostly because they’re small enough to fit into places you wouldn’t think to check and curious enough to try. A few passes through the house before your kitten arrives — or a quick catch-up if they’re already home — heads off most of the genuinely dangerous stuff, as opposed to the merely annoying stuff.
Why Kittens Get Into Everything
Kittens explore with their paws and mouths in roughly equal measure, and their small size means gaps and openings that look closed to you often aren’t closed to them. Combined with a short attention span and a lot of energy, this is a temporary phase — most cats settle into more predictable habits by around a year old — but it’s the phase where household hazards do the most damage.
Strings, Ribbons, and Small Objects — The Number One Danger
String-type items are one of the most common genuine emergencies in young cats: ribbon, thread, tinsel, hair ties, and the strings on hooded sweatshirts can be swallowed and cause serious intestinal blockages that need a vet, sometimes urgently. Keep sewing kits, gift ribbon, and dangling blind cords out of reach, and skip toys built around loose string or feathers unless you’re actively supervising play. Our toy safety FAQ covers this in more detail if you already have string-style toys in the house.
Toxic Plants and Household Chemicals
Several common houseplants (lilies are a well-known example for cats specifically) are seriously toxic, and a kitten investigating leaves by chewing them is a real risk. If you’re not certain a plant is safe, the simplest fix is moving it out of reach rather than researching every species you own. The same goes for cleaning products under the sink, laundry pods, and anything in a spray bottle — a childproof latch on those cabinets is a small effort for a real reduction in risk.
Windows, Balconies, and High Perches
Cats are confident climbers and kittens haven’t always learned their own limits yet. Make sure window screens are actually secure (not just closed) before assuming a window is safe, and treat balconies and upper-floor windows without secure screens as off-limits. A kitten that jumps toward something interesting outside a window doesn’t always judge the landing correctly.
Appliances and Tight Spaces
Washers, dryers, dishwashers, and even open recliners are genuine hazards — kittens climb into small dark spaces because it feels safe, and a machine that gets closed and started without a check can be fatal. Get in the habit of glancing inside the drum before closing the door, every time, for at least the first year. The same caution applies to reclining furniture with hidden mechanisms and gaps behind large appliances that a kitten can wedge into but not easily climb back out of.
Giving Curiosity a Safe Outlet
Proofing is easier to stick to when your kitten has satisfying, safe things to investigate instead. A collapsible cat tunnel gives them a hideaway to explore that isn’t a gap behind the refrigerator, and a plush toy without loose string is a safer outlet for the pounce-and-chew instinct than a hair tie off the bathroom floor. For supervised active play, an automatic laser toy redirects chase energy toward something designed for it. Our kitten toy buying guide has more on matching toys to this age and energy level.

Frequently Asked Questions
How long should I keep the house this carefully proofed?
Most cats grow out of the highest-risk exploring phase within the first year, but every cat’s judgment develops at its own pace. Relax restrictions gradually as your cat shows consistent good sense in a given area rather than all at once.
My kitten swallowed a piece of string or ribbon — what should I do?
Contact your vet right away rather than waiting to see if it passes on its own, and don’t try to pull a visible string out yourself if any part of it is still inside — this can cause internal damage.
Are all houseplants dangerous to kittens?
No, but toxicity varies widely by species and it’s not always obvious which ones are risky. When in doubt, keep plants out of reach or check with your vet or a poison control resource before assuming a specific plant is safe.
