Window screens

[monster]

Hello, I have a nice portascreen for the sash windows in my current flat but am going to need something different for the normal, plastic double glazed windows in the place I'm moving to in a few weeks (to keep the cats off the road out the front). Does anyone have any recommendations?

Flat Cats do a standard size screen or made to measure which are attached with a very strong Velcro, I've been using them for a few years now and wouldn't be without them now.
