This is a specific conversation about Cat window perches — giving indoor cats a view — ask about yours and get one honest answer for your exact situation.

Two Siamese at the same window is a lovely setup — but if there's only one perch, you'll almost certainly get squabbling over the prime spot. Window perches are honestly one of the best enrichment additions for indoor cats: birds, movement, sunlight, and a warm ledge all in one. The key things to get right are suction cup strength and weight rating, especially when you're planning two perches side by side. To point you in the right direction — how much does each cat weigh, what kind of windows do you have (smooth double-glazed, textured, or older single-pane), and are the two cats roughly the same size?
They're both around 5kg, pretty typical for Siamese I think. We have modern double-glazed windows with smooth flat glass. They're similar size but one is definitely the boss cat so I want them to each have their own space.

Perfect — smooth double-glazed glass is the best surface you can have for suction cup perches, they hold really reliably on it. At 5kg each you're well within the safe range for most suction-mount perches, which is reassuring. The dynamic you're describing — one dominant cat — is exactly why side-by-side matters. If the perches are at the same height, the boss will just claim both. Can I ask: is the window wide enough for two perches next to each other, or would you be open to stacking one slightly higher than the other?
The window is a standard UK sash window, probably about 70cm wide inside the frame. I think side by side might be tight. Stacking could work actually — would that stop the dominant one just bullying the other off both perches?

Stacking is actually the better solution here, and yes — height difference does reduce conflict. Cats naturally resolve hierarchy through vertical space: the dominant cat will take the higher perch and consider that a win, leaving the lower one in peace. For your setup I'd recommend two K&H Pet Products EZ Mount Window Beds. They're specifically designed to be used in multiples on the same window — the mounting hardware is independent for each unit so you can position them at different heights without them interfering with each other. Each one is rated to 9kg, so your 5kg Siamese are comfortably within that. The suction cups are large and perform very well on smooth double-glazed glass, and the fleece bed is removable and washable. Mount one about 60cm from the floor and the second roughly 30cm above that — the dominant cat will claim the top one, and both cats get uninterrupted views. That's the cleanest, most cat-logic-friendly solution for your window.
That sounds really sensible. Are the suction cups actually reliable enough that I won't come home to a cat on the floor?
inparticular.ai
On smooth double-glazed glass — yes, they're genuinely reliable. The most common reason suction cup perches fail is either textured or slightly dusty glass. Before you mount them, wipe the glass with a clean dry cloth, press each cup firmly, and then twist to lock. K&H uses oversized cups compared to cheaper alternatives, which significantly increases the hold area. I'd also suggest pressing the cup, locking it, and then leaving it unloaded for 24 hours before letting the cats use it — the seal improves as it settles. After the first week of use with no issues, you can trust it. Most failures people report happened in the first day before the seal had fully set.
Really helpful, thank you. I'll go with two of the K&H ones and try the staggered height setup.
inparticular.ai
Great choice — that staggered arrangement will suit their dynamic perfectly. Give it a few days for the boss cat to claim the top spot and settle in, and you should find the second cat relaxes into the lower perch without much fuss. Siamese are very visual cats so they'll both get a lot out of having their own uninterrupted window time. Enjoy watching them enjoy it.
