A couple years ago my cat had a urinary tract infection (I assumed - he was peeing all around the house right in front of me and there would be little if any urine and blood in it). I took him off of dry food and put some drops of Pau D'Arco Herbal Glycerite Extract into his water bowl. Within a day his behaviour changed and his kitty litter box was put to good use. He went back to being the happy crazy cat he was before - and I no longer get cheap dry food! He's never had another infection in the past couple years and he has a preference for dry food. I probably put about 10 drops or so of the extract (mine was alcohol free and from Herb Pharm) into his bowl and kept him inside to make sure he wouldn't get water from another source.... but that was about 2 years ago so I'm not sure on the exact amount.
