I use enclosures by Focus Cubed Habitats but have friends who use Zen enclosures and they are happy with them. I've seen the enclosures and they are nice, but I prefer Focus. If I kept snakes in Zen Habitats I would feel fine keeping the snakes that don't require high humidity and/or can tolerate wider humidity ranges. I have to admit I would not keep my GTP in a Zen Habitat, though I know that a youtuber (Reptilian Garden) keeps her GTP in Zen and is happy with it. Then again, Zen sponsors her channel so I take her opinions with a grain of salt.
