Biocare Insect Mesh - Ideal For Covering Windows (Grey Mesh 1.2 mt wide)

What is the mesh made from, is it cotton, fibreglass or some other material please?

Anyone with cats - Has the mesh proven strong enough to keep the cats at bay? (Ours is a big tom cat who most likely will hang off it by his claws)

After fitting the mesh, how do you use the handle to open the window?? Or am i missing something 🤣

Can you stick hook part of velcro to upvc window and then sandwich mesh between smooth velcro and hook velcro? will mesh be too thick to do this
