Care information, not veterinary or human medical advice. Contact a reptile-experienced veterinarian promptly for illness, injury, appetite or behaviour change, or concern. Seek a healthcare professional for human health concerns. Do not wait for this note or an app reply. No care change, treatment or safe waiting interval is supplied.
Twilight and night are broad descriptions
RSPCA UK describes crepuscular activity; LafeberVet describes nocturnal activity. These labels are not an appointment when every gecko must appear. This page provides no lighting timer, wake-up test or overnight observation assignment. A real change remains a matter for actual veterinary advice.
Do not turn wording into a UVB waiver
VCA says UVB is not required but recommends it; RSPCA UK gives specific UVB guidance. Merck recommends broad-spectrum lighting even for nocturnal and crepuscular reptiles. The disagreement does not justify this website selecting no UVB or copying a universal exposure. The actual arrangement needs suitable expert review.
Food and light are not separate switches
The sources connect calcium, supplements and lighting but differ in schedules and detail. We provide no supplement dose, food portion, feeding clock or substitute for lighting. An insectivore label is not a complete diet, and wild food examples are not a menu to reproduce for a pet.
No equipment task to earn an answer
Do not move a fixture, change food, take a meter reading or handle an animal to complete the temporary question. It arranges existing broad wording only. Illness, injury or other concern needs prompt reptile-veterinary advice without waiting for a measurement or app answer.
