Cat Lovers - Deadly FUS - Info all Cat Owners should read!
The Home Vet Website ^ | 1/5/1998 | Dr. Jeff

Posted on 02/24/2003 7:31:25 AM PST by Tunehead54

Cat lovers please go over this - my cat (4 years old)went from healthy to near death in less than 24 hours! We noticed (he's an outside cat) he didn't show for dinner - unusual. When I found him under a shed I thought he was dead and even got my wife to hold the light as all I could see is his tail and hips. When I dragged him out he was "out of it" but breathing! Bang out the door ... off to the vet.

Apparently neutered males are more susceptible to this. Please bump this because I'm not going to put it in Breaking News even though it was news to us. Ping any cat friends please.

Only $500 for an overnight stay at an emergency vet place plus over the weekend at our regular vet - I'm expecting another $400 minimum.

Sure wish our vet had mentioned a diet when we had our guy neutered. Whatever the "correct" cat food costs its go to be cheaper than this weekend's festivities.

Probably most important is feeding your cat properly. Shouldn't be all dry food and most brands have a special variety for urinary tract health. I'll know more when I get back from the pet store.

Thanks for listening,

Charlie

BTW the article is just one of many but my wife thought it was a good summary of the problem.

What Is Feline Cystitis?

The term "cystitis" literally means irritation of the urinary bladder. Although this term is rather general, there is a common form of cystitis that occurs in male and female cats. This disease is also known as Feline Urologic Syndrome (FUS) or Feline Lower Urinary Tract Disease (FLUTD). It affects the bladder (not the kidneys), resulting in the production of tiny crystals and bloody urine. The cat often urinates much more frequently than normal, usually with the passage of only a few drops of urine. This can be confused with constipation. Many cats will urinate in places other than the litter box due to the irritation of the bladder wall, Hard cool surfaces such as tile floors, counter tops, sinks, and bathtubs are often used. They should not be punished for doing so.

What Causes Feline Cystitis?

We are not completely sure of the cause of this problem. Bacterial infections are the most common cause of cystitis in dogs and humans, but most cats with cystitis do not have bacteria in their urine. Neutering of male cats has been proposed as a potential cause, but this has been disproved as an initiating factor. Dry foods may not initiate, but will aggravate the problem after it begins. This is because of the higher mineral content (ash) and lower water content of dry foods. A herpes virus has also been incriminated. Despite extensive research, the cause remains elusive.

Return to menu.

Are Bloody Urine and Straining to Urinate the Main Problems?

Most cats with cystitis exhibit blood in the urine and discomfort in urinating. The discomfort is usually mild but can become much worse if it is not treated. Some cats may develop stones in the bladder which can be surgically removed, or dissolved with a special diet. Male cats may develop enough crystals in the urethra (the narrow tube carrying urine out of the body) to cause an obstruction. This obstruction prevents elimination of urine from the bladder. If the obstruction is not relieved within 48 hours, most cats will die from kidney failure and the retention of toxins that were not removed by the kidneys. Because the urethra is relatively larger in the female cat, the emergency posed by complete obstruction is almost always found in male cats.

Return to menu.

How Is Cystitis Treated?

Each cat with cystitis is treated according to the changes in the urine (pH, crystals, bacteria, blood, etc.), the type of crystals present, the presenting clinical signs (straining, increased frequency, etc.), and the presence or absence of a bladder stone or urethral obstruction. The first line of treatment is always to increase water consumption, decrease minerals in the diet and decrease stress. This is accomplished by eliminating dry food, and mixing water in with the canned food (which is preferably a food which promotes an acidic urine pH) If neither a bladder stone nor urethral obstruction is present, proper medication will generally relieve the discomfort. A urinalysis is necessary to determine the proper medication. A special diet will help to dissolve crystals in the urine and hasten recovery. If the cat has an obstruction of the urethra, a catheter is passed into the bladder while he is under a short-acting anesthetic. The catheter is frequently left in place for about 24 hours. The cat is discharged from the hospital when it appears unlikely that obstruction will reoccur, usually 1-2 days later. If he is experiencing kidney failure and toxemia, intravenous fluids and additional hospitalization are needed.

Return to menu.

How Long Is Treatment Continued?

Following initial treatment, you will be asked to return the cat in 7-10 days for a recheck of the urine. This is very important because some cats will appear to feel much better, but the urine is still bloody or contains crystals. If medication is stopped based on how the cat appears to feel, treatment may terminated prematurely and a relapse will probably occur.

Return to menu.

Can Cystitis Occur Again?

After one episode of cystitis, a cat is predisposed to recurrence. This is due to both systemic and environmental factors. This is the primary reason that an appropriate diet should be fed in the future.

Return to menu.

Are There Ways to Prevent Recurrence?

Two things should be done to help prevent recurrence.

1. The most common type of crystals present in the urine are called struvite. These are dissolvable in acidic urine. Therefore, acidification of your cat's urine can be a significant means of prevention. It has been shown that environmental stress can produce the opposite of acidic (alkaline) urine. This is why cases of feline cystitis are associated with stress, e.g. travel, new pets, new people etc. Several special foods are available which acidify the urine. However, if your cat's crystals are not struvite, acidification may actually make recurrence more likely. Therefore, if at all possible, the crystals in the urine should be analyzed for their composition. This is the most important step in preventing future problems..

2. Restrict the cat's intake of dry cat food. Though dry foods do not cause cystitis, several studies have shown that the cat's total fluid intake is decreased when dry diets are fed. When the fluid intake is decreased, the urine is more concentrated with minerals and other materials that can cause future episodes of cystitis. Canned foods can result in increased fluid intake and more dilute urine. However, we know that many cats do not like canned food and that there are several distinct advantages to feeding dry food. Therefore, if there have been only a few infrequent episodes of cystitis, these other factors may be more important..

Return to menu.

What Complications May Occur Due to an Obstructed Urethra?

The most common complication of a urethral obstruction is bladder atony. Atony means that the muscles of the bladder wall are unable to contract to push out urine. This occurs when they are stretched to an extreme degree. Not all cats with obstructions develop atony. If this occurs, longer hospitalization is necessary. The muscles will nearly always rebound and become functional again, but this may take several days to over a week. Another complication that occurs occasionally is kidney damage. Although feline cystitis does not directly affect the kidneys, if the bladder becomes extremely enlarged, urine may backup into the kidneys and create enough pressure to temporarily or permanently damage them. If this occurs, prolonged hospitalization will be necessary to treat the kidney damage. However, with aggressive treatment, most cats will recover their normal kidney function. It should be noted that both complications, bladder atony and kidney damage, are the direct result of the bladder becoming extremely enlarged. Both problems may be prevented by prompt recognition of the problem and prompt medical care.

Return to menu.

My Male Cat Has Had Several Urethral Obstructions. Can This Be Prevented?

Male cats that have more than one urethral obstruction can benefit from a surgical procedure called a perineal urethrostomy. The purpose of this is to remove the narrow part of the urethra that is the typical site of the obstruction. Although this prevents future obstructions, some of these cats will still have an occasional recurrence of cystitis, though usually not as severe. This surgical procedure is also performed if the urethral obstruction is so severe that normal urine flow cannot be reestablished or if there are permanent strictures that develop in the urethra. Surgically changing the cat's urethra makes him more prone to bacterial infections in the bladder and bladder stones. Therefore, this surgery is only recommended if other means of prevention or treatment are not successful. However, the complications associated with the surgery are not life-threatening like urethral obstructions, so the surgery generally offers a significant benefit for the cat that really needs it.

Per the info you posted, it is essential to determine whether your cat is forming struvite crystals or calcium oxalate crystals, as good dietary preventive measures for the former are likely to cause in increase in the latter. There's really no point to launching into preventive measures without this info.

Perhaps I get a little irritated when I see so many pet nuts buying expensive operations and health care plans for their pets. It's pretty strange and financially irrational.

It's an amazing thing, freedom. People can actually choose to spend their money on whatever the hell they want. Whether it irritates you, or you find it strange and irrational, or not.

We feed them the best food, but occasionally, I've noticed that Taz develops the symptoms you mention. I merely mixed in a little silver water with their water and administered silver water through an eye dropper. Cleared right up.


What's "silver water" and how do you generate it?

Thanks so much for posting this information! Years ago we lost a beloved red tabby due to this aliment.

We make sure that Georgio W. Bush drinks plenty of water and we monitor hime for early signs of FUS. So far he's been doing well on IAM's dry food.

The following pair of webpages gives a partial nutritional analysis of virtually all cat foods on the market, including special prescription foods formulated to minimize crystal formation. The site is primarily designed for management of chronic renal failure, so it lists phosphorus and sodium content for each food (and not many other items that are key for other conditions), but it also lists protein and fat content, so you can compare those among the urinary tract formulations.

But pets are not livestock on a farm. They are members of the family and one gets quite close to them.

Please don't assume that my animals are just 'livestock' even if that term is technically correct and their lives are only possible because of economic utility to the society at large.

Rural people get very attached to their animals and herds.

Part of the difference between me and others here is that I have a herd outlook, not a pet outlook. Though I have very personal relationships with my cat and horses and a certain emotional attachment for the cows and their welfare as well. You just can't help it even if you try to be a cold bastard. They're not just some bunch of meat machines. They love, they have joy, they interact with you, they're smarter than most people think. Even a cow.

more people should look at these matters from a broader perspective and realize that certain choices made for individuals have consequences for the species.

That is bull...what you need to realize that the disclaimer in your first or second post "I have a farm with a lot of animals" should have told you that your problems are so different than that of a pet owner who has one, that you should have left it at that.

There is no "too much" for people who have the means to do this. From that, we learn more about animal medicine than we knew before.

There is a "too much" for people who have many animals. That is fair. I have many animals too, three of which are aged. I have to be smart about how I treat their aging, because I have to conserve resources for the others. Many don't have that problem.

BTW.... you can come up with as many reasons as you want to to shoot your pets rather than have them euthanized with drugs (I find that to be a horrible way to treat a pet), but one of those reasons cannot be that shooting them is just as 'kind' as drugs. That is ridiculous.

Well, I'll spend some, being a bit sentimental. But there is a definite limit and always keeping in mind that there are other animals who need a caring home too.

There is research that shows the drugs used in human executions may be far more cruel than anyone previously expected. A shooting squad or cyanide might be a kinder death. The same may be true of putting down animals.

Every time you open a can of 'pack in spring water' tuna, give the fluid to the cat(s), and add a bit of cool water to the mix. Increasing fluid intake is the best way to avoid the urinary tract problems. Skim milk, diluted with three to one water to milk won't give the cat the stinkies, but it will increase fluid intake.

"I have a friend whose neutered female cat absolutely refuses any people food (steak, chicken, whatever) and will eat only one brand of very cheap cat food even when offered the priciest foods but she is healthy."

That describes my neutered female cat exactly - also does better and has better stools on Chef's Blend. She hates people food so much that I've even seen her gag after sniffing some of it! Great - that's what we eat.

She's gorgeous, great thick coat - here's her pic:

Iams is the cat food we used too and our cat Paul was very healthy his entire life. It was a very sad day when he died but he had a great life. We still have a little calico, about 7 years old.

Thanx Johnny! How'd you ever guess I'd have a little experience with this topic? Could it be the 39 critters begging me to feed their starving little selves right now? LOL!!!

I'm sorry to hear about your kitty Tunehead54. I hope you got him to the vet in time to save the kidneys. If not, you're best bet, very honestly, is to let him go. Believe me, I adore cats.......we have 39 thanks to irresponsible pet owners who tire of them and dump them off near our farm. My world revolves around my "babies". But if it's to the point the cat is suffering, I don't hesitate to have it put to sleep. To me, to let it continue to suffer is just selfishness on my part, not wanting to say good bye. I know everyone has their own opinions on the matter but that's mine. I hate to see an animal suffer and it's because I do love them so much.

I've had the problem a few times with my cats but have been fortunate to have it happen primarily with the females. It's easier to treat, definitely. One male had the problem but I recognized it in time to save him. He was blocked and was catheterized for a couple of days but the meds helped and he's been fine ever since. I watch the ash content in the foods I buy and mix water with their food. I haven't had any problems for a while now. Whew! We keep our vet happy enough with all the shots and FLV tests. LOL! Wanna meet some of my "herd"? Here's a third of them, waiting to go outside. They use the kitchen window as their door. Cleaning spray is kept under the sink for use as soon as they're out. LOL!

They call me the Certified Crazy Cat Lady....can't imagine why! :-D

Very charming. It's good thing for them that they have such beautiful fur. We're helpless before their aloof and sleek furriness.

I know of other cats that are also exclusively Chef's Blend.

Whatever. Tell yourself whatever you want. I have been present when animals are put down with drugs, large and small ones. There was zero suffering. I think the potential for a screw up, fear, pain and desecration of your pet by shooting it is a much higher risk.

Iams practically killed our cat within hours of feeding it to him. It brought on an instant urinary tract crisis. There's simply no one-size-fits-all solution to this problem. See your vet for advice, and make sure the vet is well experienced in felines .


Thanks - good advice!

Dear Library Lady, See #81 & 87 - very important - in fact I'm going over the whole thread and taking notes! Thanks also for your concern.
