This is the kind of mesh
Rocky chased little Bumboo across the car park yesterday night and she ran right into the orange plastic mesh that was put up because of some construction work.
Bumboo disappeared screaming and trashing under a car. I pulled the mesh with the entangled cat out from under the car...and luckily she managed to free herself.
The rectangular holes in the mesh are big enough to allow the head of a smallish cat or kitten to get caught and the mesh is made of very tough plastic material.
