Kevin's looking great, Gio! So are the other Morelia on this thread, too -- I'm fairly confident that some sort of Morelia (or something Morelia-adjacent) will make it into this house eventually.
By chance, are any of Kevin's perches easily removable? My longi actually acts the same way sometimes when I try to take him out (though thankfully not so "pissy"), and I've found that he doesn't throw a fuss and is to content to come out when I pick him up on his perch. It's a trick that I picked up from listening to some Corallus/GTP podcasts that seems to work with semi-arboreals. Perhaps it would work with Kevin as well?
...though I imagine it might be quite something removing a snake of his size on his perch! I'm already having visions of me carrying a ~6 foot longi around the house on a tree branch...![]()
