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)

Hi, and thanks for your question.
These signs might be compatible with a urinary tract infection/inflammation. Stress related (idiopathic type of inflammation) infection and presence of crystals are the most common causes of it.
A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.
