Dr. Becker's Comments:
I want to specifically address urinary tract infections in cats because although pH issues and crystal issues can lead to feline lower urinary tract disorders -- including Feline Urologic Syndrome (FUS) -- the vast majority of the time there’s also a dietary component. And many cats end up with recurrent urinary tract infections.
How can you tell your cat has a recurrent infection happening in its bladder? Well, it could be that your vet has told you this, but other common signs include:
If you notice these signs you can presume your cat may have not only a urinary tract infection, but also inflammation present.
A urinalysis is an invaluable diagnostic tool to determine if there is blood, white blood cells or crystals present in your pet’s urine. Veterinarians can also evaluate urine sediment and determine if there are visible bacteria present in a urine sample. However, your veterinarian cannot determine exactly what bacteria is present without further testing.
A urine culture from your veterinarian can determine if your cat is dealing with a urinary tract infection as well as determine what medication must be used to treat the infection. Without culturing the bacteria present, your veterinarian has no idea what medication would be most successful in treating the infection.
Once you know for sure that your cat is dealing with urinary tract disease or infection, your veterinarian may prescribe antibiotics. Antibiotics are not necessarily a bad choice, however many cats suffer from recurrent urinary tract infections that are difficult to control and completely eliminate.
One important point all cat owners should know is how to recognize the difference between controlling a current infection and preventing additional infections from occurring.
This is where D-Mannose comes in.
D-Mannose is a wholly absorbable sugar that you feed to your kitty. It comes in capsule or powder form, which you include in your cat’s food. It’s a non-metabolizable sugar, which means it doesn’t wreck pH balance, it doesn’t wreck blood sugar, it doesn’t prompt additional pancreatic stress (insulin release), and it doesn’t change the level of good to bad bacteria in your cat’s digestive tract.
Your cat absorbs the sugar wholly and it is excreted through the kidneys and into the bladder. Bacteria are attracted to an energy source, so when D-mannose is present in the urine, the bacteria leave the lining of your cat’s bladder, clinging to the D-Mannose, and your cat voids out the bacteria.
It’s not a true antibiotic but D-Mannose absolutely has anti-microbial properties, which means it does a great job of fighting infections, naturally.
What’s especially interesting is that D-Mannose first got its roots in the large animal veterinary industry. Dairy cows, whether you know it or not, that are nursing are very predisposed to urinary tract infections. The dairy cow industry is really quite fanatical about trying to prevent urinary tract infections from occurring in dairy cows, because when dairy cows are lactating and are receiving antibiotics, the milk that is siphoned from those cows has to be thrown out because it has antibiotics in it.
So, dairy cow farmers do a good job of trying their darnedest to prevent recurrent urinary tract infections in the female herds, because it’s literally throwing out profits. About 10 to 15 years ago, dairy cow farmers were turned on to D-Mannose because it’s natural and side-effect-free, there’s no withdrawal period, which means you don’t have to throw the milk out for a period of time after it’s given, and it does a terrific job of really preventing urinary tract infections in dairy cows and large animals.
Somehow, it went from large animal veterinary medicine to human medicine and certainly many of you may have even tried it yourself. D-Mannose is being used for women who have recurrent urinary tract infections and if you’re looking for more information, Dr. Mercola covers D-Mannose excellently at Mercola.com.
However, one area that people haven’t thought about the benefits of D-Mannose is with companion animals like dogs and cats. They also suffer from recurrent urinary tract problems, and kitties especially are very prone to recurrent inflammation (cystitis) that can predispose them to infection.
My recommendation, if you have a cat that has recurrent urinary tract infections, is that you consider one of two plans. The first is pulse therapy, which means one week out of the month you put your cat on D-Mannose. The second is if your cat has consistent low-grade inflammation (chronic cystitis) that can predispose your cat to recurrent infection, I recommend adding D-Mannose into your cats’ protocol daily for preventive therapy as a means of helping to prevent infection from occurring.
Does Dr. Becker or anyone else ever monitor or bother to read any of our comments? It was asked several times, how much should the cat get, where can it be purchased (Mercola.com sells it), but does the bottle tell us what's appropriate for cats? By weight? Age? Hello!!!!! Anybody in there?
D-Mannose or anything else isn't helpful if we don't know how much/how often to use it or where to purchase it.
Wow! Thank you so much for posting this. Last year one of my cats had to have the surgery, and it appears as though the UTI is returning now since he cries a little when he starts to pee. They eat only canned food, since I have not been able to get them to eat raw food. At least they do not get grains.
Excellent information, Dr. Becker. I have a cat that is currently dealing with chronic cystitis. That's the current diagnosis anyway. She's only 2 1/2 years old so I would really like to "break the cycle" of reoccurence now. The D-Mannose makes a lot of sense. How much should a cat be given? Thank You! Sherry
My male cat has UTI, and he is always going to the doctor. The last thing I was told about is glucosamine-chondroitin . He said that they have discovered that the bladder of the cat is compsed of the same stuff that human joints are lined with, and taking GC helps. I have had him on this for several weeks now, but it doesn't seem to help much. I am trying to get more fluids into him. I will try this D-Mannose though. It sounds promising.
I called my vet and the "vacation substitute" vet gave me some measurement in grams which I tried to convert - sounded like a huge amount - so I have been using 1/4 teas powder form 3 times a day mixed in with canned food.(Kitty weighs about 13 lbs) No problems accepting it whatsoever and so far so good. I purchased mine from Swanson on line, but I will look locally before I buy again. We also changed over from dry food to wet only and since this kitty (we have 2) didn't drink enough water, have been adding a splash to their wet food as well. I have been dissappointed in our regular vet as he does teach you anything new - or preventative - I wish there was a holistic vet in our area, but alas there is not.
What is the dosage of d-manosse? for a 5 pound cat, a 10 pound cat, a 15 pound cat?
i would venture a guess that the dosage doesn't really matter. d-mannose powder goes through the body untouched, it's inert and harmless, I don' think there is such a thing as an overdose. Too much would be a waste, but if there are no more bacteria present in the bladder to attach to it, it will simply be excreted. (Imagine mopping up a small spill with a bathtowel - not efficient, but not "wrong", either. ) As a human, if I sense a UTI coming on I will take 1/2 teaspoon in a big glass of water several times a day, so that as the bacteria have a chance to build up again, I am constantly introducing a new supply of d-mannose to "sop them up".
You can get this in any health food store, or any online vitamin store, incuding Dr. Mercola's.
1/2 teaspoon to a small amount of milk twice a day.
Never heard of D-mannose. Thank you so much. On the rare ocassions a cat of mine (and I've had many) had a urinary tract infection Powdered Ester C really helped eradicate it. MY vet who'd never thought of using it thought it might be because it acidified the urine. What are your thoughts on this ?
The article doesn't tell us how much d-mannose to give the cat. Info, please, Dr. B.?
Dr. Becker u rock (<:
Please tell us where we can purchase this D-Mannose for our cat?
I never have seen a reply to the question of how much to give a cat of the D-Mannose. I would like to order for my cat. Thanks. Brenda
Hello Dr. Becker,
I just want you to know I love your articles! I am very curious as to what the dose of D-Mannose would be for animals. I have 2 cats, one that has had crystals in his urine before and would love to prevent any further issues. Also, we have 2 dogs that I would like to give D-Mannose to as well. If it is by weight, what is the dose per pound? I would love to order this from you or Dr. Mercola:) Thanks for all your help. Renee
