Reptiles also have one more type of excretion product, called urates or uric acid. This is the end product of protein digestion and is also stored in the urinary bladder as a creamy, off-white pasty semi-solid. ... When the tortoise urinates, it will pass the liquid urine and the semi-solid urates at the same time.
Perfectly normal shows all is in working order. Soak regularly and it will come out in the warm water soaks poo, urine and urates.
Heres my tortoise in a soak doing the splits ☺️ with urates. The more hydrated they are the thinner it is, if lumpy soak longer in a high sided container to encourage drinking and hydration.
