Hamsters are susceptible to the formation of stones within the urinary tract. The bladder is the only location within the urinary tract in which stones would likely be detected on physical examination by your vet.
How do I know if my hamster has bladder stones?
Signs of bladder stones can sometimes be difficult to detect, but it is usually associated with:
Urinary tract infection
Straining on urination
Blood in the urine
Increased water consumption
Can my hamster be treated?
An experienced vet may be able to remove the stones; this is accompanied by appropriate antibiotic therapy.
Dietary management to help dissolve the urinary stones and prevent their recurrence is not practical with hamsters.
