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: EZ Mount suction cups, a reinforced steel frame, a stated rating with 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.
- EZ Mount suction cups on a reinforced steel frame that is built for a heavy cat
- Two levels, and K&H says it is safe for multiple cats when installed correctly
- Lower shelf works as a landing step for older cats that no longer jump to sill height
- Removable, machine-washable fleece pads, and the frame folds up against the glass so blinds still work
- Needs a large clear pane, listed at 27 inches wide by 31 inches tall or more
- 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.
- Cordless braced metal-pipe frame 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
- Needs glass thicker than 5 mm and enough flat span, so measure before ordering
- Cups need periodic reseating, sometimes a hot water soak, and some long-term owners report frame hardware loosening
- The maker page lists no weight capacity, so a very heavy cat is a reason to go the other way
