Cat perch that won't stress your rabbit

Window perches are genuinely one of the best things you can do for an indoor cat — natural stimulation from birds, movement, and sunlight makes a real difference to their wellbeing. The critical things to get right are suction cup strength and a weight rating that actually matches your cat. Now, your setup is a bit more nuanced than most: you've got a rabbit near the window, which means you need a perch that gives your cat a satisfying vantage point without turning the rabbit's cage into a staring contest. Totally solvable. Can you tell me how heavy your cat is, what kind of windows you have (smooth double-glazed, older textured glass, etc.), and whether the rabbit cage sits directly below the window or to the side?

That's a really common layout and the tension is real — a cat sitting directly above a rabbit at eye level is stressful for the rabbit even if the cat is calm. The trick is getting the perch high enough that the cat is clearly above the rabbit's sightline, rather than hovering at the same level. What's the window height like — is there enough glass above the hutch level to mount a perch a good 30–40cm higher than the rabbit cage top?

Perfect — that gives you exactly what you need. I'd go with the K&H Pet Products EZ Mount Window Bed. It's a hammock-style suction cup perch rated to 9kg, so your 5kg cat is comfortably within range, and the suction cups are genuinely strong on smooth double-glazed glass. Mount it up high in that clear space above the hutch — the cat gets a brilliant outdoor view and a warm sunbathing spot, but critically they're elevated well above the rabbit rather than looming directly over it. Rabbits read threat from lateral staring far more than from something clearly above them, and the height separation tends to break that fixated predator posture cats fall into. The hammock design also means the cat sinks into it slightly, which naturally softens their silhouette from below. One thing worth doing: put it on the side of the window slightly away from directly above the hutch if you can, even 20cm of horizontal offset helps the rabbit feel less targeted.

The K&H holds up well on clean smooth glass — the key is prep. Wipe the glass with a dry cloth before mounting, press each cup firmly and give the lever or tab a full lock, then leave it unloaded for a few hours before letting the cat on it. Most suction cup failures happen because people mount on slightly dusty or cold glass. On double-glazed windows in a warm room this one is reliable. A quick weekly press-check keeps it solid long term. Given the rabbit situation I'd also avoid mounting near a drafty frame edge where temperature fluctuation could weaken the seal.

Great choice for this setup. Mount it high, offset it slightly from directly above the hutch, and your cat gets a proper enriching perch while the rabbit keeps its peace. Both pets will settle into the arrangement faster than you'd expect once the positioning is right.
