Check mounting compatibility, the cat’s route and the window environment before treating a perch as ready for everyday access.

1. Installing on an unapproved surface

Read the requirements for the exact attachment system. Similar-looking glass, trim or replacement fittings may behave differently. If the surface is outside the instructions, choose another installation rather than experimenting with the cat’s weight.

2. Reading the load limit too narrowly

Include all intended occupants and added bedding when reviewing the stated limit. Do not assume the product is suitable for shared use. Follow the manufacturer’s installation and inspection method before allowing access.

3. Forgetting the approach and descent

Check the jump or intermediate surface in both directions. Keep landing areas stable and clear. A comfortable platform can still be a poor choice if reaching it requires an awkward or unreliable route.

4. Trusting an ordinary insect screen

Do not rely on a standard insect screen to contain a cat. Keep the window arrangement secure independently of the perch. Review the opening mechanism and remove reachable blind cords or other entanglement hazards.

5. Cleaning without resetting the mounts

Removing covers or washing glass can disturb the installation. Follow the attachment system’s instructions for drying, refitting and checking. Do not assume a previously secure fitting remains correct after maintenance.

6. Ignoring changes through the day

Observe sunlight, temperature and nearby activity during likely use. A pleasant morning position may differ later. Provide an alternative resting location rather than assuming the window is always the most comfortable option.

7. Continuing after repeated slipping

Remove the perch from use and investigate the mounting problem. Do not use the cat as a test load or improvise unsupported adhesives. Replace unsuitable equipment or choose a different approved installation.

Put inspection on the cleaning sequence

When the glass or cover is cleaned, include refitting and checking every attachment according to the instructions. Keep the perch unavailable until complete. A simple written sequence helps prevent a caregiver from restoring the cushion while overlooking a disturbed mount. Remove the item if any part cannot be made secure as designed.
