Eriathwen
Adult Guinea Pig
Poor old Tilly is off to the vet in a little bit, she's been passing big clumps of calcium sludge when peeing, today her urine is slightly brown, having tested it there's no trace of blood, but some ketones and protein unfortunately looking like her kidneys are starting to struggle. At 8.5ish years old though, she's done pretty well, I'm hopeful the vet will have a way to keep her more comfortable.
