Experiment Cot Confinement underway !!

And Fang is defintly unimpressed by my efforts at creating a cot from which he cannot escape !!! Its too low though so he cannot stand upp, then again he doesn't need to stand up when hes asleep does he !!!!! Am thinking now along the lines of attaching hinges to the cot base,( which is now the lid ! ) and then can simply lift the lid to put him to bed !! If I attach it higher up then it will give him room to stand up without him being able to escape !
