only thing I can suggest it putting his pouch on outside of his cage (if he in house finding turds and crumbs of food anywhere?) if not then can hope for best luck and tie it to a tree and check it every morning and see if he in it by luck. also if in apartment let others know he escaped he might of just found a place to stay until you find him ( bumming on someone couch type deal if lucky) I never get up hope until a body is found or you have sub 50 temps fora week)
as for the stuff ( if you mean his cage and such put it on Craigslist or see if a local glider rescue can use any of it ( never waste a good cage )
