K&H Pet Products EZ Mount Double Stack Cat Window Perch for Large Cats, Steel Frame, Suction Cups, 2 Washable Review (2026)

What the double stack design offers

This K&H perch stacks two separate hammock levels on the same steel frame, mounted to a window with push and turn EZ Mount suction cups. The idea is to let two cats each claim a level without competing for the same spot, or to give one cat two sunny options depending on the time of day and where the light falls. Each level has its own soft fleece sleeping area measuring 23 by 12 inches, and the whole unit is built around a reinforced, high-grade steel frame rather than lighter materials, which the manufacturer credits with the added durability needed to support two occupied levels at once.

Weight capacity and mounting

K&H rates the industrial-strength EZ Mount suction cups and steel frame to hold up to 50 pounds, and the company states the cups are designed to install in seconds without tools or drilling into the window frame. Like other suction-mounted perches, the hold depends on a clean, smooth glass surface, so any dust, film, or texture on the window will weaken the seal over time. The design carries a U.S. patent, which points to a purpose-built suction and frame system rather than a generic mount adapted from another product, though buyers should still expect to re-press the cups occasionally as part of normal upkeep.

Window size requirements

This double stack unit needs a window glass space of 27 inches wide by 31 inches tall or larger to fit both levels, which is noticeably taller than most single-level perches. Apartment renters with shorter or narrower windows, or windows broken up by grids and mullions, will not have enough continuous clear glass to mount this properly. Because the unit covers more of the window than a single-level perch, it will also block more of the view and natural light coming through, a tradeoff worth considering for anyone who values keeping their window mostly clear when the perch is not in active use.

Cleaning and folding

Both shelf covers are removable and machine washable, an important detail for multi-cat households where two cats shedding onto the fabric can build up fur and dander faster than a single-cat setup would. The whole frame folds up against the glass in seconds, which lets blinds, curtains, or shades operate normally without needing to uninstall the perch first, a detail that matters in apartments where the same window handles both light control and lounging duty. The one-year limited warranty backing the frame and suction system gives some reassurance against manufacturing defects, though it does not cover normal suction wear from dust and window film. Washing both covers on a regular rotation, rather than waiting until they visibly need it, keeps the fleece from matting down under two cats' worth of regular use.

Who should choose the double stack over a single level

This model makes the most sense for households with two cats that want to avoid territory disputes over a single perch, or for one cat owner who wants a taller, more prominent window feature with two usable levels. Single-cat households without space concerns may find the single-level K&H perch a better fit, since it needs a smaller clear glass area and blocks less of the window. Given the steel frame, washable covers, and generous weight rating, this is a durable option for multi-cat apartments as long as the window has the height to support it. Measuring the glass pane before ordering is worth the extra few minutes, since returning a bulky window perch is more of a hassle than double-checking dimensions up front, especially in a rental where you cannot alter the window frame itself.
