I had a geriatric female cat who had recurring URI symptoms which did not respond to abx therapy...just kept returning. What finally resolved her symptoms was a homeopathec remedy. Her symptoms did not return after that. The remedy was one mixed by an alt. vet and he did not disclose what was in it, but I may be able to find out. There are also standard homeopathic remedies for treating urinary symptoms available.
URI's are usually more uncomfortable/annoying for female cats and not a life-threatening situation as it can be for a male cat who becomes plugged up and needs to be catheterized. Your post about the new info for URI's is interesting...look forward to hearing more about it. Sally in San Jose
