Before offering calcium with vitamin d3 powder
- Check the exact animal and preparation: the listed suitability is Bearded dragons; Leopard geckos; Crested geckos; Chameleons; Amphibians. A food being edible does not make it a complete diet.
- Follow the preparation advice: Place insects in a bag or tub with a pinch of powder and shake to coat lightly. Do not substitute a seasoned or processed version and assume the same safety.
- Portion guidance: Follow a species-specific schedule, typically calcium without D3 at most feedings and calcium with D3 once or twice weekly. For a pet on a prescribed diet, discuss extras with the vet first.
- If your pet develops vomiting, diarrhoea or discomfort, stop offering the extra and seek advice. Suspected poisoning or breathing difficulty needs immediate veterinary help.
