A climber needs somewhere to climb to
Climbing is not misbehaviour in a kitten; it is how a young cat maps her territory, escapes trouble, and finds the warm, high vantage points cats are built to seek. A home that offers no legal height simply guarantees she will select her own, from curtain rails, wardrobe tops and the refrigerator. Install the sanctioned route first: a tall cat tree with a stable base, or a stepped shelving path, placed where the household actually spends time, since a tree exiled to a spare room will lose to the bookcase beside the sofa. Make the top pay, with the best view, a comfortable bed and occasional treats appearing there, so the approved summit becomes her default destination.
Audit the house from one metre off the floor
Get down to kitten eye level and travel the rooms she can reach, looking for what her climbing will disturb or endanger. Push fragile and heavy objects well back from shelf edges, because a climbing kitten dislodges things by landing, not by pushing deliberately. Secure bookcases and any furniture that rocks when leaned on, since a piece that tips under a grown cat will certainly tip under a scrambling kitten. Tuck cables into covers or behind furniture, especially around the desks and entertainment units she will climb first, and move medicines, cleaning products and small swallowable items into closed cupboards, because height alone stops protecting them the day her climbing improves, which is to say, this week.
Plants, curtains and the other casualties
Check every reachable plant against reliable advice on plants that are unsafe for cats, and move or rehome anything doubtful rather than relying on the kitten leaving it alone; climbers chew what they land beside. Expect curtains to be climbed and, if they matter to you, swap in blinds or shorter curtains in the kitten's rooms for this season of her life rather than fighting a daily battle you will lose. Protect the tops she will use as runways by clearing them entirely, and accept a slightly more minimal home for a few months as the reasonable price of a kitten learning her routes on safe surfaces instead of valuable ones.
Redirect to the route, every single time
When she launches up the bookcase, lift her calmly to the nearest legal perch without scolding, and make the tree the more interesting option in that moment with a toy or treat. Consistency is the whole mechanism: a route that is sometimes allowed becomes a lottery she will keep playing, while one that is always interrupted and replaced by a better option fades from her habits. Scratching often happens at height too, so ensure the tree includes a tall post she can stretch fully against, and place another post near the sofa she is most tempted to use. If climbing is paired with frantic, unsettled behaviour rather than exploration, or she injures herself in repeated falls, raise it at a check-up instead of only managing the furniture.
One map of the house rules for everyone
Climbing management unravels when one person lifts her down, another laughs and photographs the curtain ascent, and a third leaves a forbidden shelf newly stocked with fragile things. Agree the legal routes, the protected items and the redirect response, and write them where the household and any sitters will see them. KinsLe Family Sharing keeps those house rules with your kitten's profile and care details, so everyone who shares her home works from the same map of what is hers to climb.
