Hi. My guinea pig Daisy is eight years old and has had recurring UTIs for most of her life. 17 days ago, I noticed blood in her urine and she was prescribed SMZ-TMP, which did not make the blood go away. She was then given enrofloxacin, assuming that the bacteria had developed antibiotic resistance. This antibiotic did not work either and I had an x-ray done which, I have attached a photo of. The vet said that she either has stones clumped together or mineralization of the bladder wall. She said that an ultrasound will have to be done to find out which it is, which Daisy is being scheduled for. The vet also said that bladder mineralization can be caused by recurrent bladder issues and that this condition isn't very treatable. I am wondering if anyone has heard of this condition and if any advice can be given. Any advice will be appreciated. Thank you so much.
