I was trying out an animal plastics rack that was given to me in a trade, well the tubs had about a half inch gap that i thought was too small for my pastel to squeeze through. Turns out it was too big a gap he got out , lucky for me I walk into my room and he had just crawled up the rack to the higher level and was hanging out he has since been put in my regular escape proof rack .
It's funny when I walked in he was looking in the spiders tub as if to either make fun of him like haha I'm out here or to say hey come join me, then I said "Houdini what are you doing?" he turned to me as if to say oh crap I'm busted.
So happy he was in plain sight and have taken proper precautions to make sure it never happens again
