Choose the corner with a kitten's priorities
The right corner is quiet, draught-free, away from the room's main walking route, and close enough to family life that the kitten hears ordinary voices and sounds without being in the middle of them. A spot near a radiator that cycles on and off, or under a window with direct hot sun, gives her temperature swings she cannot yet manage, so prefer an internal wall with steady conditions. If the room is large, define the nursery with a playpen or a low barrier at first, because a tiny kitten in a whole room can feel exposed and can also wander too far from her tray to make it back in time. The corner should be a place you can sit comfortably too, since your presence in it is part of the furnishing.
Lay out the essentials in the right relationship
Place the bed at the most sheltered point, with bedding that holds her scent and can be washed in rotation so one familiar-smelling layer always remains. Put food and water at a clear distance from the litter tray, because cats strongly prefer not to eat near their toilet, and keep the tray itself low-sided enough for short legs to step into without a climb. Add a small scratching post or pad, a couple of safe toys, and, for a very young kitten, the gentle heat source at one end of the bed described in good orphan-care guidance. Fresh water belongs in the corner at all times, refreshed when you visit rather than on a schedule she cannot predict.
Make the corner safe at her scale
Safety-proofing a nursery corner means inspecting it from ground level. Block the gaps behind and under furniture that border the corner, because a small kitten can squeeze into a space she cannot reverse out of and become trapped silently. Lift cables, blind cords and chargers out of reach, remove small objects she could swallow, and check that nothing heavy stands where her climbing could bring it down. If other pets use the room, the corner needs a barrier they respect or supervision whenever they share the space, since the nursery's purpose, a place where she is never ambushed, collapses if a boisterous dog can wander into it at will.
Keep the layout boringly unchanged
Young kittens navigate by memory and scent far more than by sight, so a nursery that is rearranged every few days is a nursery she has to relearn constantly, and litter accidents are usually the first sign. Keep bed, tray, bowls and post in their places while she is small, clean around them rather than relocating them, and expand her territory by opening the room in stages instead of moving her base. As she grows confident, the corner naturally becomes her bedroom within a larger home range, and you will see her return to it to sleep and regroup long after she no longer technically needs it, which is the surest evidence the setup did its job.
Notes that let anyone run the corner
A nursery corner works only if every carer maintains it identically: which bowl, which side the tray sits, how the heat source is refreshed, and what must never be moved. Write those details down where the household and any helper will actually see them, rather than relying on a tour given once. KinsLe Family Sharing keeps the nursery notes with your kitten's profile and care information, shared with the family members who help, so a feed covered by someone else leaves the corner exactly as the kitten expects to find it.
