UVB radiation is essential for most captive reptiles, yet its absence remains one of the most common preventable welfare failures in reptile keeping.
Metabolic bone disease from UVB deficiency is one of the most painful and common preventable conditions seen by exotic animal vets. Bones soften, fractures occur spontaneously, and animals experience chronic pain for months before diagnosis. The tragedy is entirely preventable with correct lighting. But many reptile owners are unaware that UV-emitting bulbs must be replaced on schedule — not just when they fail visually. Education is the primary welfare intervention.
