I have a 10 year-old calico who has what is becoming a chronic bladder crystal problem. She has been treated 4 times with anti-biotics and diet. The first treatment was a success, but after a month the crystals returned. The last 3 treatments were not effective. The symptoms are very frequent attempts to urinate and pink urine. The vet is now recommending surgery. Is anyone familiar with this surgery? Is it safe for a 10 year old cat? Is the recovery easy? Is it effective? Are the results lasting? Surgery is the last thing I want to do, but of course I will do it if it is the only way to go. Does anyone have any other suggestions for treating bladder crystals? Supplements, homeopathic remedies, food change, etc? I would really appreciate any help. This has been going on for a few months and I need to do something. Thank you.
