Reptiles are among the most commonly kept exotic pets worldwide, yet their welfare needs are frequently misunderstood. Evidence-based husbandry transforms outcomes.
Pet reptile welfare suffers enormously from the widespread perception that these animals have simple needs and low sentience. Reptiles are ectothermic and physiologically dependent on appropriate temperature ranges for all metabolic functions including digestion, immune function, and reproduction. Inadequate thermal gradients cause chronic physiological dysfunction. UVB lighting is essential for vitamin D3 synthesis in many diurnal species; its absence causes metabolic bone disease, a painful and progressive condition. Psychological needs vary by species: some tolerate handling; others find it chronically stressful. Species-specific research is essential before acquisition of any reptile species.
