Jack Cage Mesh is a versatile, heavy duty mesh with good viewing properties. It is ideal for cages or pen housing small animals such as rabbits and guinea pigs. Note: It is recommended that new galvanised wire mesh used in aviaries and pet cages be treated to remove excess zinc that could possibly harm pets. Shave off any zinc spikes with a utility knife. The mesh should then be scrubbed with a mild solution of vinegar (2 cups in a bucket of water), and rinsed with clean water.
