Reptiles kept as pets have complex temperature, humidity, and behavioral needs that are frequently inadequately met, resulting in widespread welfare compromise.
Reptile welfare in captivity is poorly served by widespread misunderstanding of their needs. As ectotherms, reptiles depend on environmental temperature gradients to regulate body temperature — a fundamental physiological requirement that requires thoughtful terrarium design. Inadequate UV-B lighting causes metabolic bone disease in many species. Most reptile keepers underestimate the space, thermal management, and behavioral enrichment their pets require, resulting in chronic welfare deficits that manifest as immune suppression, abnormal behavior, and shortened lifespans.
