Almost every apartment has the same problem: your cat wants the window, and the sill is three inches deep. The K&H EZ Mount window perch is the answer most owners run into first, because it skips the sill entirely and sticks a padded cradle onto the glass with heavy suction cups. It has been the default suggestion in cat groups for years, which is exactly why it deserves a closer look.
K&H sells the EZ Mount system in a plain version and in a heated version, and the two suit very different homes. This review covers how the mounting behaves, which windows it works on, and when a bracket design is the smarter call. If you are still weighing perch styles in general, our hub guide to the cat window perch is the wider view.

Quick Answer
Is the K&H EZ Mount window perch worth buying?
- Yes, if you have smooth, clean, untextured glass and a shallow sill. The suction mount gives a cat a real lookout in a spot that was previously useless.
- No, if your windows are frosted, textured, leaded, or heavily coated, or if the frame blocks a flat run of glass. Suction needs a smooth surface to grip.
- Pick the heated version for drafty rooms, senior cats, and winter window watching. Pick the plain version if there is no outlet nearby or your cat already runs warm.
K&H EZ Mount Window Perch at a Glance
K&H Pet Products builds the EZ Mount line around one idea: put the bed on the glass, not on the sill. Here is the profile in one view before we get into how it holds up.
| Detail | What to know |
|---|---|
| Product type | Suction cup mounted window perch, sits directly against the glass |
| Brand | K&H Pet Products, a long-running US pet bedding maker |
| Mounting | Heavy duty suction cups pressed onto clean glass, no drilling and no hardware in the wall |
| Construction | Rigid frame with a padded surface, shaped as a shallow cradle so the cat settles in rather than on top |
| Cover | Removable and machine washable |
| Versions | Unheated, and a heated variant with a low wattage element and a power cord |
| Capacity | K&H lists a hold well above the weight of any housecat, though real grip depends on the glass |
| Ideal for | Renters, shallow or absent sills, apartments, homes where drilling is not an option |
| Less ideal for | Textured or frosted glass, very large or nervous cats, windows without a clear flat panel |
| Care | Wash the cover, wipe the cups and the glass with rubbing alcohol, and reseat the mount every few months |
What It Gets Right
The core promise holds up. Cats want height plus a view, and the average modern sill is far too narrow to lie on. Mounting to the glass turns a spot your cat was already trying to balance on into a proper bed, without a single hole in the wall. For renters that is the whole argument, and it is a strong one.
The cradle shape is smarter than it looks. A flat shelf leaves a cat feeling exposed at height, while a shallow curved surface with raised edges gives contact on more than one side. Owners report cats settling in for long naps rather than sitting for a few minutes, which is the difference between a perch that gets used daily and one that becomes a shelf for junk mail.
Washability is the quiet win. A sunny perch collects fur and dust faster than any other cat bed in the house, and a cover you can pull off and machine wash keeps it usable for years, where cheaper hammocks often have fixed covers. Installation is quick too: clean the glass, press the cups, done in a few minutes with no tools.
Where It Falls Short
Everything depends on your glass. Suction cups need a smooth, non porous, flat surface, and a surprising number of windows do not offer one. Frosted panes, textured glass, leaded panels, some low emissivity coatings, and small divided lights all reduce or eliminate the grip. Before ordering, put a hand flat on the pane and ask whether you have a clear smooth area big enough for the whole footprint.
Even on good glass, suction is not maintenance free. Cups lose vacuum slowly, and faster with the temperature swings a sunny window delivers every day. The fix is simple, wipe the glass and the cups with rubbing alcohol and press them home firmly every few months, but it is a habit you have to keep. Owners who report a perch coming loose almost always describe a mount that went unchecked for a long time.
Size is the third limit. This is a perch for one average adult cat rather than a sprawling Maine Coon, two cats will not share it, and a heavy cat that lands hard puts far more sudden load on the cups than a steady climber does. Give the mount a firm tug before you trust it, and place it low enough that a fall would be short. Our guide to cat furniture safety covers the same logic for climbing furniture generally. Some cats also simply refuse to trust anything that hangs in mid air, which is a temperament question rather than a product fault.
Heated Versus Unheated: Which One Fits Your Home
K&H is best known for heated pet bedding, so it is no surprise the EZ Mount idea exists in both forms. The heated variant adds a low wattage element under the sleeping surface, designed to warm to around a cat’s normal resting temperature rather than to run hot, plus a cord that has to reach an outlet.
Go heated if the window is a cold one, if the room is drafty in winter, or if you have a senior or thin coated cat who abandons the perch as soon as the season turns. A window is the coldest surface in most rooms, and gentle heat is what keeps a cat there in January instead of on the radiator. Our roundup of the best heated cat bed options compares mounted, flat, and bolstered designs.
Stay unheated if there is no outlet near the window, if you dislike a visible cord in a living room, or if your cat already seeks out cool tile in summer. Either way, keep the cord out of chewing range and unplug it if the cat starts investigating it.
Check It Out
How we chose: we compared window mounted perches on mounting method, surface size, cover washability, and how consistently owners describe the mount holding over time. K&H sells several EZ Mount shapes under similar names, so confirm the version and the heating on the listing before you order.
🏆 Best Overall
The plain suction mounted window bed: a padded cradle, a washable cover, and four heavy duty cups that go up in minutes with no tools. The sensible default for a shallow sill on smooth glass.
Who It Is For, and Who Should Skip It
Buy it if you rent and cannot drill, if your sills are too narrow to nap on, or if your cat already spends its afternoon trying to balance on a window ledge. It suits average sized adult cats, single cat homes, and rooms where a floor standing tree would eat space you do not have.
Skip it if your windows are textured, frosted, or divided into small panes, if you have a very large breed or two cats who want the same spot, or if your cat dislikes surfaces that move under its weight. In those cases a bracket mounted or sill resting design removes the whole question, and our guide to the suction cup cat window perch walks through which glass types work and which do not.
Alternatives Worth Considering
If the suction route is not right for your window or your cat, these three cover the most common alternatives.
🔥 Best for Cold Rooms
The heated Kitty Sill from the same maker, resting on the sill rather than gripping the glass, with a gentle warming element and a removable washable cover. Worth it for senior cats and single glazed windows, as long as you have an outlet within cord reach.
💛 Best Value
A simple fabric window hammock on a metal frame with suction cups. You give up the padded cradle and some build quality, but it is a low commitment way to see whether your cat will use a hanging perch at all.
🔩 Also Great: No Suction Required
A perch that rests on the sill or fixes to the frame with brackets instead of gripping the glass. The answer for textured windows, big cats, and anyone who would rather not check a mount every few months.
Frequently Asked Questions
Will the suction cups really hold my cat? On clean, smooth, flat glass, yes, and K&H rates the mount well above any housecat’s weight. Grip depends on the glass surface more than on the cat, so textured or coated panes are the real risk factor.
How often should I reseat the mount? Check it monthly with a firm tug and reseat it every few months, or sooner if the window gets strong direct sun. Wipe both the cups and the glass with rubbing alcohol first, since even a thin film of cleaner residue weakens the seal.
Is there a heated version? Yes. K&H offers the EZ Mount design with a low wattage warming element as well as unheated, and the heated one needs an outlet within cord reach. Our heated cat bed guide compares it with flat pads and bolstered beds.
Can two cats use it at once? No, treat it as a single cat perch. With two window watchers, mount two perches rather than hoping they will share.
Does it work on double glazed or coated windows? Usually yes on standard double glazing, since the inner pane is still smooth glass. Some privacy and low emissivity coatings, plus any frosted or textured finish, can defeat the cups.
My cat ignores it. What now? Give it a week with a familiar blanket on the surface and treats placed on it, and check the height, since a perch mounted too high puts cats off. The wider window perch guide covers placement in more detail.
The Bottom Line
The K&H EZ Mount window perch solves a real problem without tools: it turns a useless narrow sill into a genuine cat bed with a view. Its weakness is entirely in the mounting, so smooth clean glass and a reseating habit are non negotiable, and textured windows or very large cats push you toward a bracket design. Choose the heated version for cold rooms and older cats, and the plain one everywhere else.
