Dark brown urine with large white cluster

[lydiaroman31]

My African Spurred Tortoise or sulcata tortoise is peeing dark brown reddish and today there were pretty large clusters of urites in his urine. We just moved to Virginia. I’m worried he may have eaten something bad while foraging. Please help

Dark brown urine means he needs to see a vet immediately. I don't want to frighten you, but it could mean significant kidney damage.
