Six months is the kitten energy summit: the body is athletic, the confidence is new, and the hunting sequence is switching on at full strength. A kitten at this age does not have a behaviour problem to suppress — they have a daily energy budget that will be spent somewhere, and the owner's whole job is deciding where. Curtains get climbed when they are the tallest, most interesting vertical in the kitten's world at the exact moment a burst arrives; scheduled play and a better climbing landscape remove both halves of that equation.
The hunt-cycle session, run properly
Play in three or four daily sessions of roughly ten minutes, spread across the day with the last one shortly before your own bedtime, because the pre-bed session is the one that buys the household a quiet night. Run each session as a real hunt in miniature. Drag a wand toy away from the kitten, not toward them, letting it pause, twitch and hide half behind furniture, since prey that runs in straight lines in the open bores a predator quickly. Build to fast chases, then slow the game down and let the kitten catch and hold the toy — a hunt that never ends in a catch leaves a kitten more wound up than no hunt at all. After the final catch, offer a small meal immediately, completing the sequence the kitten is wired for: hunt, catch, eat, groom, sleep.
Redirecting the curtain route
Do not simply guard the curtains — outcompete them. Place a tall, stable scratcher right beside the favourite curtain, tall enough for a full vertical stretch and sturdy enough not to wobble, and add a shelf, cat tree or cleared bookcase level nearby so the upward route continues somewhere legal and more interesting than fabric. Reward every use of the approved route with play or a treat in the first weeks, and when the kitten does launch at a curtain, respond without drama: lift them down calmly, carry them to the scratcher, and start a game there — the lesson is a redirection, not a telling-off, and shouting only adds excitement to the event. Rotate boxes, tunnels and paper bags through the room every few days as well; novelty is fuel at this age, and a landscape that changes slightly stays more attractive than furniture that never does.
Solo outlets between sessions
Interactive play does the heavy lifting, but a six-month-old also needs somewhere to put the smaller bursts that arrive between sessions. Offer puzzle feeders that make part of the daily ration get worked for, a rotating cast of kickable toys and balls refreshed from a cupboard rather than all left out to go stale, and a window perch with a view of birds or street life, which occupies a young cat's hunting brain surprisingly well. Time the solo outlets for the moments you cannot play: a puzzle feeder set down as you leave for work covers the morning burst that would otherwise find the curtains.
What not to do, and what to expect
Never use hands or feet as the toy, even through bedding, even when the ambush is adorable: you are rehearsing the exact hunting behaviour you will live with in an adult cat, and unlearning it later is miserable for everyone. Equally, do not punish curtain climbing with water sprays or shouting; a kitten punished mid-burst learns that you are volatile, not that the scratcher is better, and may simply climb at 4 a.m. instead. Expect the peak to be genuinely intense for some weeks and to soften gradually as the kitten matures; if energy ever comes with appetite loss, hiding or a sudden change in litter habits, that combination is a vet conversation rather than a play problem. When every person plays the same hunt game at the agreed times, curtains stop being the sport, and a Care Teams schedule in KinsLe quietly proves which session length actually settles your kitten overnight.
