Pet's info: Small Animal | Guinea Pig | Female | spayed | 4 years and 2 months old | 3 lbs
My guinea pig has gritty, chalky urine deposits at her urethral opening (picture is of my shirt after holding her) and pain when urinating. Can this be caused by the very high mineral content in the ground water in my area? Her diet is as recommended. Her two cage mates have no issues. How can I help her? Thanks, Helena (from Denmark)

These signs are compatible with the presence of a urinary tract infection due to crystals but stones may be present as well. Diet (certain food is rich in Calcium here you can see a list of them http://www.guinealynx.info/diet_order-cal.html), water mineral content and individual predisposition are all possible causes. If you already considered all these predisposing factors, a check up to rule out urinary /bladder stones is required.
