K&H Pet Products EZ Mount Double Stack Kitty Sill Cat Window Perch vs AMOSIJOY Foldable Cat Window Perch with Metal Frame
Which should you buy? Our verdict on both, pulled from our full The Best Cat Window Perches: 4 Compared (and One to Skip) comparison.
The K&H wins on hardware and track record: the largest push-and-turn cups in the group, steel shelf frames, generous rating headroom, and two levels for multi-cat homes. The AMOSIJOY is the better load path and the better-looking object for a single cat, provided your glass clears its stated thickness and span minimums.

K&H Pet Products EZ Mount Double Stack Kitty Sill Cat Window Perch
Buy itThe best suction hardware in the category, on steel-framed shelves that give two cats one window.
- Largest push-and-turn cups here, with a mechanism that actively pulls air out as you tighten
- Steel rod shelf frames stay flat under a heavy cat instead of folding
- Two decks with a pass-through cut-out, so two cats share a window without negotiating
- Lower shelf works as a landing step for older cats that no longer jump to sill height
- Strap-suspended, so the upper cups take a peel load rather than pure shear
- Looks like equipment: black steel and grey fleece in the middle of your window

AMOSIJOY Foldable Cat Window Perch with Metal Frame
Buy itCordless bracing loads the cups in shear, keeps the glass clear, and the reversible cover covers both seasons.
- Rigid brackets and a metal arm brace against the glass, the more favorable load geometry
- No cords across the window, so the view stays clean and nothing snags on the climb up
- Reversible cover: warm plush one side, breathable mesh the other, zips off to wash
- Folds flat in one motion, so curtains and blinds still work
- Real minimums for glass thickness and flat span, and the owners with hold problems mostly skipped measuring
- Cups need periodic reseating, sometimes a hot water soak, and some long-term owners report frame hardware loosening
- Rated below the K&H, so a very heavy cat is a reason to go the other way
