My cat had blood in urine but has now cleared up and he is urinating normally. After a urine test however, the vet said there are crystal present. He has been on synulox antibiotics, garlic & fenugreek and vegetable tablets to help with urination. The vet now wants to do an x ray of the bladder to see if there are stones or crystals present. Does any one know if it is normal practice to investigate this way? I am concerned with exposure to radiation if it uneccessary. Thanks in advance for any comments.
