If a suction-cup window bed starts slipping or detaching, do not assume the cause from one symptom alone. Recheck the exact model, mounting surface, suction cups and manufacturer installation steps before putting the perch back into use.
Quick answer
For the K&H EZ Mount Window Bed currently linked by Zavyro, the manufacturer’s instructions are straightforward: use a suitable solid glass pane, thoroughly clean and dry the window, clean the suction cups with mild detergent, rinse them thoroughly and dry them completely, then mount the product as instructed. K&H recommends cleaning the window and suction cups regularly, with monthly cleaning recommended.
K&H also notes that warm suction cups are easier to mount and suggests warming them in hot water or in the sun for a few minutes before installation.
Key takeaways
- Use the instructions for the exact model. K&H sells several EZ Mount products with different cups and different glass requirements.
- Start with clean, dry surfaces. That is the manufacturer’s instruction for the legacy EZ Mount Window Bed.
- Clean monthly. K&H recommends monthly cleaning of the window and suction cups.
- Warm cups can be easier to mount. K&H gives this as a mounting hint.
- Replace damaged or incompatible cups with the correct K&H replacement type. K&H lists model-specific replacement cup sets.
- Do not add oils, glue or other improvised materials unless the manufacturer explicitly approves them.
1. If the perch slips or falls
Several things can contribute: residue or dust on the glass, residue on the cup rim, incomplete installation, a cup that is damaged or no longer flexible, an unsuitable pane, or the wrong replacement cup for the model. A fall by itself does not prove which one occurred.
Remove the perch and restart from the manufacturer’s installation instructions rather than simply pressing a loose cup back onto the glass.
2. Recheck the window first
For the older EZ Mount Window Bed sold in the current Zavyro listing, K&H states that the solid glass pane must be at least 27 in wide and 11 in high. Newer K&H window-perch designs publish different requirements, so do not mix their measurements.

3. Manufacturer-based mounting routine
- Remove the perch. Inspect the cups and mounting hardware for visible damage or deformation.
- Clean the window. K&H says to thoroughly clean the window and make sure it is completely dry and free from residue.
- Clean the suction cups. Use mild detergent, rinse thoroughly and dry the cups completely.
- Warm the cups if needed. K&H says warm cups are easier to mount and suggests hot water or a few minutes in the sun.
- Install the perch according to the model instructions. Press the suction cups firmly as directed by K&H.
- Recheck the installation before use. If a cup does not hold as intended or shows damage, stop using the perch until the issue is resolved.
This guide intentionally does not recommend wetting the cup rim, adding petroleum jelly, oil, glue or tape. Those steps are not part of the K&H instructions used here.
4. Monthly maintenance
K&H recommends regularly cleaning the window and suction cups and specifically recommends a monthly interval. Cleaning requires removing the cups from the glass, so the product is remounted after the surfaces are clean and dry.
If a suction cup is damaged, permanently deformed or no longer functioning correctly, use the correct replacement part for the exact EZ Mount model. K&H’s replacement-cup page lists several different cup types because the parts are not universal across every mounting position.
5. Do not overinterpret the weight rating
K&H states that the suction cups on the legacy EZ Mount Window Bed hold up to 50 lb. Treat that as the manufacturer’s load rating for the product. It does not prove that a particular pane, installation or multi-cat setup is suitable, and it should not be converted into an invented dynamic-load safety margin.
6. A practical placement precaution
As a Zavyro precaution rather than a manufacturer specification, avoid mounting an elevated perch over stairs, sharp furniture edges or other hazards that would make any accidental detachment more consequential. Make sure the cat has a practical route on and off the perch, and provide another resting place elsewhere.
If your cat has a new mobility or vision problem or has started falling, discuss that change with your veterinarian rather than treating it only as a furniture problem.

8. FAQ
How often should I clean the suction cups?
K&H recommends monthly cleaning of the suction cups and window surface.
Should the cups be wet when I mount them?
The K&H instructions used for this legacy Window Bed say to rinse the cups and dry them completely before mounting. This guide follows that instruction rather than adding a separate wet-rim method.
Does cold weather mean the perch will fail?
We cannot confirm a universal winter failure rule. K&H does say that warm suction cups are easier to mount and suggests warming them before installation.
Can I use oil, petroleum jelly, tape or glue?
Those additions are not part of the manufacturer instructions used here, so this guide does not recommend them.
How much weight does this model hold?
K&H states up to 50 lb for the legacy EZ Mount Window Bed. Ratings differ by model.
