Step 1: The Theory Behind the Fence
By attaching plastic mesh garden fencing to my wooden fence, I have been able to keep my cats in and the neighbor cats out (for the most part).
Step 2: Supplies Needed
4' Vinyl coated garden posts (Lowes) Count the number of 4x4 posts that are holding up your fence and buy that many.
40" Green garden fencing (Lowes) This comes in 25' rolls, buy the same length as the fence you are going to attach it to.
2' of 2x4 boards (scrap boards will do)
1' of 2x2 board (also scrap)
1/2" Plastic leg tips (Home Depot) One for every garden post.
Hacksaw or Saber Saw With Metal Cutting Blade
1/2" Electric Drill
1/2" Drill bit
Electric or Manual Staple Gun with 1/2" or 9/16" staples
Chop saw or Radial Arm Saw
