I want to open the windows now that spring has finally arrived. My crew could chew thru the current screens in seconds! Does anyone have some suggestions for something like a grate or a safe chicken wire type thing I can install between the glass and mesh screening? I want to leave the current screens there to keep bugs out, but I need to add something to keep the crew from escaping. I slid a window open for barely 5 minutes and someone chewed a hole already! So no more fresh air until I figure out what to do.
