The info I was going to give, is on a computer the wifi went out on. However, I used Google and searched several ways for woods safe to parrots and foods. YouTube.com is also another research tool with a search window. I copy and paste to a Desktop folder these various articles or even video's sometime. Youtube has a save function and you can make a folder in it. Grapevine is a safe wood, a coffee tree (not bush), Eucalyptus, Bamboo, Dogwood, Crab apple, Magnolia or Rubber tree for a few. OMG, there are so many "DON"T's" though. Plants, fruit pits like apple, avacado (at all), candles and scents, teflon in the kitchen. By all means skim this site's various threads and topics. jh PS: By all means don't be afraid to build the play gym yourself. Here is a fairly simple way. Use grapevine that is dried and whittle the ends to fit into pvc or its fittings. Use the pvc pipe and fittings to join the grapevine horizontal pieces. Use pure stainless steel or other no toxic metal hardware. Peel the bark from grapevine (or which other wood), lightly sand, soak in few gals of water with 1 tablespoon of bleach for 1 hour, then rinse seally well with fresh water and dry in oven at 250 degree's F (article says); then whittle end's to tight fit in pvc connectors and drill small guide hole into fitting so as to put a screw into the wood. I would be glad to consult. Same name on facebook. jh
