Health & WellbeingMy cat has bloody urine, no UTI. Is it FLUTD, FIC, or idiopathic?
I'm so sorry that you are dealing with this with Fred. Since there is blood in her urine, I would first continue to look for medical causes of blood in the urine if she doesn't have a history of urinary tract problems. Here is more information on FLUTD. http://www.veterinarypartner.com/Content.plx?P=A&C=&A=611&SourceID= From that handout, in older cats (over 10 years old), here is the distribution of why they have FLUTD... 50% will have true urinary tract infections. 10% will have bladder stones. 17% will have a combination of infection and bladder stone. 7% will have urethral blockage. 3% will have urinary tract cancer. 5% will not have a cause that can be determined despite extensive testing. 66% will be in some stage of kidney failure. 5% will have urinary incontinence. So, my first recommendation if there is still blood in Fred's urine is to have your vet run a urine culture. That requires the urine to be sent to the lab to see if they can grow any bacteria from the urine. This
