Bladder Stones -------------- Hamsters are susceptible to formation of stones within the urinary tract. The bladder is the only location within the urinary tract in which stones would likely be detected upon physical examination by a veterinarian. Signs of bladder stones may or may not be detected by hamster owners and are usually associated with infection within the urinary tract, frequent urination, straining on urination, blood in the urine, increased water consumption, listlessness and inappetence. An experienced veterinarian 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 reccurrence is not practical with hamsters.
