Sometimes you can improve such 'hides' by crumpling a paper towel or two & stuff them in. Keep in mind snakes prefer hides with doorways just big enough
to fit thru (with a meal) & that some commercially-available hides have lovely dramatic 'doorways' that snakes hate. They make them so people can see their
pets, but snakes feel stressed & vulnerable...same goes for those open-ended tree bark tunnels...they're fine as "cage furniture" but not actually as hides. I
like to use them sometimes in front of their actual hides...like the protected canopy in front of a fine hotel,-they work fine that way. It's all about privacy.
Snakes don't like high ceilings either. Just think of a home decor magazine, & do the opposite for a snake, lol...
