Soaking tortoises are important because the normal waste product for protein metabolism is ammonia. Tortoises convert this ammonia to uric acid, which is less toxic to the bladder wall and lets them hold water in their bladder for long periods of time.
Do you need to soak a tortoise?
So, why do tortoises need to soak? Tortoises need to soak twice a week or so to help them stay hydrated and clean. This keeps them strong and healthy, avoiding getting sick from dehydration or bacteria that can build up on their body. Tortoises also need to soak so that the shell and the skin do not crack from dryness.
How often should you soak a tortoise?
Unless directed by a veterinarian, only bathe your tortoise once every few weeks, or if the tortoise has built up grime under her arms. Tortoises are naturally quite dirty, and this is normal. They do not need frequent baths, but one every now and again won't hurt.
