Invisible Grille for Corridor window

[Zoom1337]

Hi!

Am currently renovating my home and I'm planning to get Invisible Grilles for the following reasons:
1. Gonna get a cat
2. Aesthetics

However, my HDB flat is a corridor unit and I'm worried if invisible grilles are recommended due to safety issue.

Did my research around but can't seem to get any information regarding it's reliability in this aspect..

Hoping to get some insight on this
