Hello, I originally wrote back in May 2009 about my cat Spillo who has been suffering from cystitis for most of his life. I just wrote recently saying that he reached the one year mark and he was in total remission. Well he had a change last week and the information I found out from the vet in very important for those who want to use ACV long term. Last Wednesday Spillo started peeing what looked like pure blood. I took him to the cat hospital and the vet said his bladder felt small and very hard. He was there for a few days and basically what he ended up having was a severe bladder infection (on the first feel the vet thought it might be cancer). The vet said that ACV used (daily like we were giving to Spillo) will make the ph very alkaline. Alkaline is good when you are trying to prevent crystals, but when you go too alkaline it becomes a breeding ground for bacteria.
Bottom line, if you are going to use acv long term, maybe check with your vet about the quantity. We discussed the dosage with the vet and he thinks that 1cc 2 to 3 times a week is plenty sufficient. The one good thing about this visit is that the urinalysis showed that Spillo had no crystals or questionable blood cells in his bladder. ACV does work and is very good for cats with this problem. I will continue to give 1cc of raw acv to Spillo twice a week.
