BaseGoal All-Weather Trellis Netting Mesh Plant Garden Vine Growing Flexible String Net (3.5" Mesh ployester, 5' Wx 30'L)

Does it support watermelon

I have a large (and unattractive) cinder block wall in my backyard. Would this work to put up on the wall for vining plants?

Will this work for grapes?

If you bought the 3.5" could a cat get its head through?
