My sulcata tortoise was chilling in his water bowl enclosure when i noticed that there was this white powder in the bowl when my tortoise left. Is this normal?
Yes, that is urates
However, that bowl should not be used. They need a clay saucer one they can fit into and not have to climb up to.
The urates need to be like a tooth paste texture. If they are powdery or gritty or hard chunks your tortoise is dehydrated.
Your tortoise is also starting to pyramid and needs high humidity of 80% in a closed chamber enclosure.
