Due to our cats excitement watching critters both at home and in the rig, I used Pfifer Pet Screen to replace flimsy OEM screening. Stuff is strong enough to support a 23 lb. cat climbing it on a doorwall screen. It comes with spline, but if you carefully remove the spline from your RV screen, it works better due to the smaller thickness. Using a pointed tool, remove the glue from the corners of the screen before trying to remove the spline.
