Is this hide good enough for my girl Luna?

I have been using this hide for about 1 month now, Luna (my albino bp) uses it VERY OFTEN as it has a heating pad (with thermostat of course :gj:) and she seems to love it but I am wondering if it is too open? She readily accepts food at feeding time weekly and doesn't seem to be in any discomfort so I am assuming she is doing ok?

Not sure if you tried adding a photo, but I don't see it.

If it's working though, then it's fine.

Cave-style snug hides are generally recommended, but if she's eating I see no reason to fix what ain't broken. :gj:

Sorry friends, just added a pic, and don't worry those cords for the thermometer/hygrometer are on the OUTSIDE of the tank ;)
