i was told minimum size for a grown on to adult yemen cham would be a 4-6 foot high, 2 foot long and 1 foot in depth viv made of either mesh all over or wood and glass with plenty of vents. this one cham in interested in comes with a wooden viv (glass at the front) and its 4foot long. it wont fit in a car. so...does a viv really need to be that long? chams need more height i know, and i havnt got room for another 4foot viv next to my beardies viv. a 2 or 3 foot long one yes, and height isnt a problem.
