Right, that's got the cats sorted - I've just ordered some of this
I will do what my father did - cut it in lengths and bend it into 'tunnels' - I will make 'hoops' out of galvanised wire and thread them through the 'tunnels' at the ends and in the middle and place them over the seed rows - this will keep the cat off - I will not be beaten by a cat!!!
I have 2 cats and I've been doing that for ages. Also use smaller "squares" which I put over bare patches in the flower beds where I've planted seedlings, can move them from place to place. Works fine!
