[Blue Feather]

Does anyone have any ideas to prevent our new rescue cat from puncturing our polytunnel plastic, without banning him completely. He has an addiction for catching moths and butterflies and leaps up the polytunnel walls to catch them, making lots of holes in our plastic!

Sorry, I can't think of much except perhaps draping 3' wide lightweight fleece loosely against the side walls.  When he repeatedly gets tangled in it, that might deter him eventually (as long as you are there to disentangle him)  Cats do hate to look foolish
