as far as i no they can jump about 2inchs maybe and as for the wall i think they probs can climb it coz its rough i have some breez blocks in another room and my dragon can climb it.
I am amazed at how high they can jump! Always frightens me a bit when they jump off something that I think is too tall. I try not to let her jump off things that are up high.
i witnessed mine get atop its house and attempt to jump out of its cage even tho the screen top was on.. found it quite funny he jumped a good 4-6 in. and hes still small
