Urinary Blockage in Cats (Feline Urinary Syndrome)


Just thought I would share this with all the cat owners out there

who don't know this or maybe I'm the only one who didn't. Cats are


prone to urinary tract blockage or disease. It is caused by a

blockage as small as a grain of sand size crystal or stone which

forms in the urinary tract and causes a blockage. Having an outside

cat I was unaware of this and almost lost a beloved member of our

family today. Not to mention spending more than my mortgage on vet

bills to save him.

Yes our cat has had this. Our vet suggested to make sure your cat

gets a lot of liquids, giving them broth, and stay away from cat

foods which contain fish and seafood. There is special cat food

made for this condition Purina makes one. (01/28/2005)

My male cat was continuously getting urinary tract infections and I

spent several thousand dollars on his vet bills. I tried the special


food and it did not help at all. I read a magazine article that said

stress could cause the infection in nervous cats. Rufus was

definitely a nervous cat so I thought that might be the problem, but

the article offered no solution.

After a little brainstorming, I decided to try sprinkling

Chamomile tea leaves on his food. He quit having tract infections,

so it must have worked. Sadly, his kidneys had been so damaged from

all the previous infections that he died 3 years later from kidney


Ask your vet if he or she thinks this could be an option for your

cat. My aunt had a cat who was prone to urinary tract infections and

he had some kind of surgery. It cost a fortune, but it worked. I

probably paid more in total vet bills than she did for the one

operation, but my vet never offered an operation. You might want to


ask about this as well. (06/18/2005)

Urinary Tract Infection in cats

My cat used to have this problem, and she kept getting the

infections. I took her to specialists, and paid a lot of money, only

to discover on my own that it was a Christmas Cactus that was

causing it. I found the teeth marks in the leaves, too the plant

away and she has not had another one since. Hope this helps someone.

I work at an animal hospital and my male cat got blocked. Also he

had never had a UTI infection before he got blocked. I had the

surgery two days later for him. As most of you know, getting blocked

can be fatal for a cat. The surgery was two months ago. He is on his

special diet with no treats. But he is still showing signs of a UTI.

He has been on all the meds and so forth and nothing is helping.

Luckily though with the surgery I do not have to worry about him

getting blocked again. But I do have to worry about Kidney problems

in the future. So I hope this helps people that think surgery will

fix it. (03/11/2007)

Please, please be careful of Purina Indoor Cat Chow. It is the one

that comes in the green bag.
After 3 weeks of giving this food to my cat, his urinary tract

blocked. I never knew anything about this, but apparently that

particular food has a very high amount of magnesium in it, and

that's what blocked poor Wiley's tract.

He is fine now, I have switched his food and paid the 1300 dollar

vet bill. I have spoken with several veterinarians who have told me

that Purina Indoor Cat Chow has been the cause of many urinary

blockages,sometimes resulting in deaths of cats.
Please be careful. (05/03/2007)

If you feed your cat Science Diet from the time you bring it home,

FUS should be a non-issue. I know it's too late for those pets

mentioned in the posts, but remember this for future pets.

Urinary Blockage in Cats (Feline Urinary Syndrome)

I've had 3 male cats that blocked with the crystals in the urine. I

lost the first two with the problem. The vets would just unplug them

and send me home with them. The 3rd time, I went to a different vet

that had an assistant that had about 13 cats of her own. This time

the cat was hospitalized for 3 days and not returned to me until he

was stabilized. They then explained the importance of the cat's diet

in controlling this problem.

I have fed only Hill's Feline CD or Purina UR, both prescription

diets, since to all my cats (current population is 4 males and 11

females) and have not had the plugged up male problem. My last

problem was about 12 years ago and that male is still a healthy 15

year old today. The prescription diets are expensive, but my

personal experience has been that they are worth every penny in

prevention as they are high quality foods and I have very few health

issues given the number of animals I care for.

I do have a female with reoccurring bacterial infections of the

urinary tract, a different problem, and this feed does not prevent

her problems from coming back. She is a crippled Manx with birth

defects in the hindquarters which may contribute to her problems.

My 3 year old male cat BUBBA had a UTI last year that was cured by

meds. This past week he showed signs of another and instead of

bringing him in we tried feeding him food that would help with the

UTI. The next morning he was throwing up. I figured it was from the

new food because we had never changed his food before. After a few

hours of him getting sick I took him into the Vet who felt his

bladder and told me it was as hard as a rock.

He had a blockage and that was causing him to get sick. At that

point he was too damaged and it was too expensive to try to cure

him, we had to put him down. They wanted $700-$1000 to try to do

surgery when the Vet let us know it was a bad case of blockage and

that he felt would be difficult to do. I guess in some cases they

even have to remove part of the penis to clear the blockage. I

didn't want to put him through all that. We are lost and lonely

without him, but after reading some posts about how blockage can

reoccur in most cats I know it was better to not have him go through

all the pain.

My advice is to read the labels on your cat food and make sure

that there is not a lot of magnesium. We used Purina Complete Care

(blue bag) high in magnesium, which we had no idea made it worse. I

would also advise you to take your cat in ASAP when he is showing

signs of a UTI. Good luck to all you owners who may have to make the

same decision I did. It is hard, but it is better for the cat.

I have had two bouts with this disease in my many many years of

owning cats; one made it ($1200) and the other, sadly was being

cared for while I was away and they thought he was just missing me.

By the time I got home and realized what was happening, it was too

late. This was over 8 years ago. I finally found out then that fish

meal in dry food is what causes the blockages.

Since then, I read the ingredients on all dry food meticulously

and never buy any with fish meal, no matter how small the

concentration. I have not had an issue since then. I believe that

manufacturers know of this possibility but are just not saying

anything. If you look at the Purina One Urinary Tract dry food, it

has no fish meal. I stick with Chicken based foods.

I am a Rescue Agency volunteer and have had, over the years, many

many male cats. I have 8 in my household right now. Hope this info

helps some of you avoid a very painful episode for your cat and

heartache for you. (08/12/2008)

Blockages are caused by urine that is PH imbalanced. I would

recommend that anyone with a male cat feed a urinary tract formula

food. They are made to have balance the PH and help keep crystals

from forming. Crystals form, roll around in the bladder, become like

grains of sand, roll around some more and turn into stones (kind of

like a snowball accumulating the more it rolls). Also, your vet may

sell a tablet called DLM. Basically, you smash up one tablet a day

and put it into a teaspoon of canned food. Easy solutions for such a

huge problem in male cats. Best of luck to everyone with male cats.

My cat is back from a four day, 1200 dollar, stay in the hospital

because of FUS. It's been quite an ordeal, and although he is home,

he isn't better. We asked the vet about the food because all that I

read on this page, and he told us that it isn't the food. It is the

cat. He said that about 5% of the cats in the world have a

sensitivity to magnesium, an element used to preserve the food.

Purina products happen to have a very high content of magnesium

which causes the blockages. He likened it to a lactose intolerant

person. It isn't the milk that is bad, but the way the person

processes the milk. It can be present forever or it can suddenly

develop. So, we need to be vigilant about the magnesium content in

the foods that we serve our pets. This adventure has surely taught

me a lot. I hope that the information helped. (09/29/2008)

My Hunter kitty, male is 8. He has been fighting struvite crystals

for 6 years. Even some prescription foods did not work. So far it

has been a year since his last crystal formation. We use Purina

Prescription UR st/ox. Store brand urinary formulas were not

successful either. I hate the Pur RX Ur st/ox because it is so

expensive and makes him overweight, but it has worked the best so

far. Lots of late night and one Christmas day vet adventures over

the years, but he is so worth it.

My cat Spice had a bladder blockage twice. The first time we were

about to go to bed and my brother was petting Spice and he just

collapsed into his water. We rushed him to the emergency room and

they said it was OK he just had a bladder blockage. The second time

me my brother, sister, and dad were in our room until my sister came

out and she saw spice peeing on our dog bed just a little spot and

we knew he had a bladder blockage. He still is in the emergency room

he will be out tomorrow.

Here are signs to tell your cat has a bladder blockage. They will

vomit. Pee a little bit in a weird place. Have odd behavior. Not

eating. (01/12/2009)

I am hoping to pick up my boy, Mikko, from the ER vet by tomorrow.

He is a 9 year old black point Siamese and an integral part of our

The bill is up to $1500 now. I'm not sure how I will pay, but I

figure they can't "repo" him once he is better, so what else could I

do for a member of the family? This is the 2nd time he's had a

complete blockage, and twice had partial blockages. I won't go into

the details of each time. However please learn from my mistakes and

from the things that I have done right.

Most of all, be vigilant if your cat exhibits signs of

distress.You may see these as simply annoying and not realize there

is a serious problem looming. The formation of crystals is most

common in neutered males, as you can all glean from the other

comments here. If you have a male, be ever more suspicious of the

following symptoms if they develop in your cat.


  • Peeing around the house, especially when the urine has strong

    odor, dark color, or even the pink/red of blood.

  • Straining or " tail shivering" while urinating
  • Lots of licking under the tail
  • Either more listless or more restless than usual
  • Frequent in/out of the litter box
  • Attempting to urinate without producing much urine
  • Unusual irritability/aggressiveness
  • Crying and/or pacing around restlessly
  • Gradual or abrupt loss of appetite
  • A smell of urine on the cat himself

    Especially watch for these signs within 1 to 3 weeks after any

    change of diet, or even changing to a different water dish. Some

    cats will refuse to drink from metal or plastic because of the

    slight taint those materials can flavor the water with.

    I have tried most of the over-the-counter type foods that can be

    bought outside a vets office. They claim to be for "urinary tract

    health", but beware this can mean different things. There are all

    sorts of less serious issues that these foods may help prevent.

    However, if you have a cat who develops crystals, and the older the

    cat becomes the more persistent this problem can become, these "over

    the counter" foods are often "not" going to prevent a panicked run

    to the vet due to another blockage.

    The best preventative I found are the prescription diets you can

    only obtain through a veterinarian. Royal Canin SO and Hills

    Science Diet C/D. That is, unless you have the time and ability to

    formulate the raw/natural diets that you can create yourself. I know

    some who've had good luck with this, but I don't have the time to

    prepare these meals myself on daily basis.

    Do encourage plenty of fresh clean water in whatever way works

    for your cat. You might have to do some trial and error here.

    Do feed wet food with extra water (room temp or slightly warm

    seems to work best). You can supply dry food as a supplement (see

    above), but not as the primary diet.

    Do not mix other foods in with your cat's urinary health diet

    because you think that he might like something "different" once in a


    Do give "Uriease" treats, (if your cat will eat them). There are

    liquid supplements as well, just do a little research to find ones

    available to you that are effective and can be easily mixed with

    food. Try just a tiny amount at first and gradually increase to

    correct dosage as your cat gets used to the taste/smell.

    Caution: If you vary from the above due to financial strain or

    other reasons you will regret it. Don't try to cut corners because

    you and your favorite lil friend will pay much more dearly in the

    long run. You, financially, and he with stress and pain and

    possibly his life.

    If you should see the signs of blockage, this is "not" one of

    those things that can wait a day or two. Your cat "will" likely die

    if he is not treated within 12 hours or so. The sooner he can be

    treated, the better his chances !!re. I nearly lost my Mikko the

    first time and my heart goes out to those of you who have lost your

    own. (02/15/2009)
