Cat window perch for older less mobile cats

Window perches are honestly one of the best enrichment additions you can make for an indoor cat — birds, passing movement, patches of sunlight, it all adds up to genuine daily stimulation that makes a real difference to their wellbeing. For a less mobile cat, the priority shifts a little: you want something with solid suction cups rated well above the cat's weight, but also side bolster walls so they can lean and feel secure without having to hold themselves upright. Before I point you in the right direction — how heavy is your cat, what kind of windows do you have (smooth glass, double-glazed, textured?), and is this just for the one cat?

Perfect — 4.5kg is well within range for most suction-cup perches, and smooth double-glazed glass is actually the best surface you can have for suction cups holding reliably. At nine years old with reduced mobility, the thing I'd be most focused on is that bolster cushion around the sides. She'll want to lean into something rather than balance upright, especially if her joints are a bit stiff. Can I ask — does she still jump to windowsill height on her own, or are you planning to add a step or ramp to help her get up?

That's a really sensible approach — giving her an intermediate step means she'll actually use the perch rather than avoiding it because the jump feels too much. Based on everything you've said, I'd go with the K&H Pet Products EZ Mount Kitty Sill with Bolster. It's a well-established perch with a thick, wraparound bolster cushion on three sides, which is exactly what a less mobile cat needs to feel supported and settled rather than perched tensely. The suction cups are strong and well-reviewed for smooth double-glazed glass, and the weight rating is comfortable for a 4.5kg cat. The platform itself is generously sized so she has room to shift position without feeling precarious. It's straightforward to fit, and the cover is removable for washing — worth noting at her age if she's spending long, relaxed stretches up there.

The main things are: clean the glass thoroughly before you attach them — any dust or grease and they won't seal properly. Press each cup firmly and twist slightly as you push. Then give it 24 hours before letting her use it, so the seal has time to set. After that, check them every couple of weeks by giving the perch a firm tug. If one has loosened, remove it, wipe the glass and cup clean, and reattach. Most failures come from dirty glass at the point of fitting rather than the cups themselves being weak. With smooth double-glazed glass and a cat under 5kg, you should have no issues with the K&H.

You're welcome — she sounds like she'll really take to it, especially with the stool in place to make the approach easy. The bolster sides will make a genuine difference for a cat her age. Enjoy watching her reclaim her birdwatching spot.
