Large scheffelera or ficus ali are my faves. Pothos is great for cover but offers no structure for climbing, but the vines are great to drape around your cage. I have picked them up at Lowes, Home Depot & at greenhouses. After bringing plants home you should always give them a good wash in your shower stall to clean them of any pesticides and chemicals. Then re-pot them in a new washed pot using organic soil with no perilite or vermiculite, on the off chance your cham decides to eat dirt. In my experience they seem to be attracted to the perilite or foam balls in commercial potting soil. A good drainage layer in the pot helps the plant handle all the water it will get inside a cage. A grow light like a 6500K fluorescent tube from Lowes or even wal-mart will REALLY benefit the plants and brighten your cage nicely. Here are a few photos of my cage for my largest mellers, Plinko. Also check out summoner12's free range set-ups... lotsa great ideas there. Cheers! Oh yea... how did the vet visit go?
