You must have a much heavier version of deer fence available than what I can find here. I use the stuff to keep songbirds away from fruit I want to be able to harvest. I have seen a bunny go right through it as well as a turkey hen. The stuff that I have access to tears very easily. The only deterrent it would be to an owl is if the owl got entangled in it. It did work well as a snake trap. A bull snake crawled up into a twisted up section until it got stuck and could not go forward or back out.
