Pain causes them to stop eating. The stone blocks the urethra (?) plus the sheer size of it causes the colon to be compressed so waste can't pass through, and the size of the stone presses on the nerves, which may cause temporary back leg paralysis.

Is this most common in Sulcata?
It sounds like an $75 xray every few years could be money well spent.
1. What are the symptoms of a bladder stone?
2. If a Sulcata had a bladder stone removed in the past, are they more susceptible to developing them in the future, or is it totally management related?
3. Any veterinary teaching University (ie Texas A&M Vet School) would have all the necessary exotic specialists and equipment to deal with tort issues and are very good at working with you financially.
