Reptiles are commonly kept pets but their welfare needs — precise temperatures, UVB lighting, humidity, and appropriate diet — are frequently misunderstood, leading to widespread chronic welfare problems.
A bearded dragon without adequate UVB develops metabolic bone disease causing painful skeletal deformities. A ball python kept too cool cannot digest meals, leading to regurgitation and nutrient deficiency. These are not rare outcomes — they are common consequences of inadequate preparation. Reptile keeping requires significant research investment before acquisition.
