When Luna is checked for her Uti,s do they culture her urine?If so what is the bacteria? If there is not any bacteria it could be Idiopathic Cystitis. I have a 13 year old female who has had it for 7 years. I treat her with glucosamine and a completly wet food diet with added water to the food.I hope it is not Idiopathic because having A cause is better than never knowing why.Best wishes for Luna I hope the bloodwork is just normal for her.katslady
