Build a route through the rooms
An apartment needs more than one cat tree in the corner. Give the Siamese a route from a quiet bed to a window, a scratching post and a higher resting place. A shelf, a stable tree and a clear landing spot can turn a modest room into a place with choices.[1]
Keep the key resources apart. Food, water, litter, resting places, hiding spots and scratchers serve different moments of a cat's day. FelineVMA guidance recommends that cats have choice and separation among these resources. That principle matters even more when every room has several human jobs.[1]
Treat the litter space like real living space
Put the box where the cat can reach it without passing a noisy machine, a slamming door or a busy kitchen path. Make it large enough for turning and digging. Scoop often enough that the box remains an easy choice, then keep the same basic setup through the first weeks.[1][2]
An accident is information, not a reason for punishment. Cornell explains that litter problems can involve a medical issue, the box, the location or a change in the cat's environment. Check the practical details, note what changed and ask a veterinarian for help when the pattern continues.[2]
Make an honest plan for the voice
GCCF describes the Siamese as a breed with a distinctive voice. In an apartment, that is part of the household soundscape. Think about early meetings, work calls, bedtime and the wall you share with a neighbor. A cat's calling cannot be designed away with a prettier room.[3]
What you can build is a more satisfying indoor day. Put play near the times when the household is already awake, leave safe places to climb and watch, and keep a calm retreat away from the front door. The home then gives an active cat something useful to do before it asks you for company.[1][3]

A steady high perch gives the cat a way to step out of the main route, watch the room and rest in a compact home.[3][1]
A good apartment fit when the cat has choices and the voice has a place
Let the cat use the apartment in layers
A practical Siamese apartment has a quiet low spot, a reliable high spot and clear paths between food, litter and play. Once that structure is in place, make sure the cat's voice still fits the life happening around it.[3][1]
