I'm wondering what your thinking is behind this fairly controversial black & white statement.
Because I keep my small collection in display-style enclosures (T8s), giving my animals the opportunity to thermoregulate without compromising their need to feel secure is something I feel is beneficial to their health and well-being. An easy way to provide a feeling of security is to provide a hide. More hides = more security. Of course, there are other situations and other enclosures that this is not necessary (many rack systems, for example). However, for most hobbyists (especially new keepers), the cost of a second hide is far lower than the potential negative effects of a ball python that doesn't feel comfortable in its own home.
Thoughts?
