In 4 years, I've never had a problem with my cham escaping or falling out of the Chameleon Canopy. However, it is important to keep all vines and perches trimmed so they don't extend out over the edge of the bottom bowl. If they fall into the bowl, they hit the slanted sides and it really should be no problem for them. Also, I ordered an accessory that was called a "habitat expander" which is basically a clear, stiff plastic sheet that installed all around the circumference of the bottom bowl and extends the "edge" of the bottom bowl by another 6 " all around. If they fall, they hit this plastic sheet and slide down into the bottom bowl. They then grab the rope and climb back up. I have not had any electrical problems as legendchams describe in 4 years but remember, these are not the same guys who made the Chameleon Canopy, so maybe do their wiring differently. All I know is that my cham really thrives on the Canopy, it looks good and pretty easy to maintain. But it does have it's problems....the leaky drip system is basically unfixable once it starts and is a pain in the ass. BTW, humidity for a veiled is pretty much taken care of by the drip vine and the live plants...the plant roots stay wet all the time and constantly let out evaporated water, and the leaves of the live plants expirate moisture also. It's very easy to get 40% humidity just by running the drip slowly for 4-5 hours per day....about 2 quarts of water(the resevoir holds 1 gallon)
