looks like its going to be awsome! the tree should look great, do you think the foam will withstand monitor claws then?
currently collecting materials for mine, also designing it to be pulled apart in sections, the plan is to be able to set it up as a single square(ish) box, an L shaped enclosure and also as 2 separate enclosures connected by plastic tunnels, approx 9 x 7' floor space in the enclosure itself. when in L shaped setup, i'm building some walls which will allow him to roam outside his enclosure sometimes, giving a total of 9 x 12.5' roaming space - infact more than that, as one section will have 2 floors - hard to describe in text, still finalizing the designs, i'll post them up once i've finished the details
