I remember reading somewhere that there was a drug one could give an
animal to make their urine fluoresce or change color if it contained
blood. I have a multiple-cat household with a number of
semi-permanent rescues and I hate to start caging to find which one
is ill. None appear to be acting ill but then cats frequently don't.
All I can find in Google is test strips to identify blood in urine,
but I already know there is blood. Which cat is the problem.
My vet doesn't seem to know of this drug, or at least the office
staff doesn't.

Does it exist? Is it safe? What should I ask my vet to order? Can
anyone point me to a web site?

I don't know if these are safe for cats, but two drugs used in human
medicine that color urine are Pyridium, a urinary anesthetic, and
methylene blue, which might be hard to find as it has only specialized
clinical applications. Pyridium colors urine a brilliant red-orange,
which will stain cloth.

That just stains the urine and would let you isolate the cat to which
you gave it. Blood often fluoresces; there's a spray used in forensics
that intensifies it. Again, that's not much better than caging.

I can think of some approaches, but they would involve considerable
laboratory support and expense.

Thanks, I guess it's continue caging till I find the right cat. I've
started with the males but so far no luck.

The link below mentions using fluorescein to help identify which cat is
the culprit urinator:
