Jack Aviary mesh is an economical, small aperture lightweight mesh, ideal for most small home variety birds. It allows good visibility into the aviary whilst keeping the vermin out. 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.
