so notice the wire on the ground, folded and doubled over will get grass over it eventually, and nothing can dig under the fence.
The wire on the top is cut strips of 2x4 welded wire.
I just sit in a lawnchair and cut strips, then attach with small wire ties and poultry net staples.
The note here is that you have large sharp wire cutters and cut the wire at as slanted an angle as you can, so the resulting cut is very sharp, not blunt.
I then go along and point the sharp ends in different directions so any critter climbing the posts will get nailed on his way up, and all along the top to discourage any other critters !
Good luck !
Greg also had alot of computer discs and other glittery stuff to scare off intruders too.
Guess I should also explain that the fence with flight netting on top, and green plastic netting around the bottom is the baby pen, and the other big pen just has the cut wire around the top.
Get a big trap Jess ! They had fun and food at your house they will surely return !!
