Regularly observing your cat's poop and pee is an important means of grasping your cat's state of health. It is a necessary skill to be a qualified pooper scooper, well, a skill that smells.

Stool color, quantity and odor

How can we be able to tell if our cat has a health problem by looking at his stool?

Generally speaking, if the cat's stool and urination (peeing) are different relative to the cat's usual in terms of frequency, color, odor (smell) and other factors, then we need to be vigilant. Plus the cat's mood is also not right, then take it to the animal hospital to ask the veterinarian to take a look.

Has bugs

If worms such as drooling worms are found in the poop, take the real thing to the doctor.

Free-range cats are occasionally infected with a parasite called Manson. Sometimes it can be more than 1m in length and 1cm wide like a flat surface that hangs down from the butt hole.

Depending on the worms, the type and amount of medication used by the veterinarian will be different, so please try to bring the actual worms with you. 


Cat poop should have the same odor if a specific food. It is easy to notice the characteristic odor when there is an abnormality.

For example, "blood odor" and "sulfur odor".


If a cat is passing large quantities of coarse and relatively soft stools, the first impression is that it's quite healthy, and it may give the impression that it's eating and pooping well and digesting well.

However, in reality, a large amount of stool basically means that the food is not well digested. Unmeasured traders will mix some poorly digested food into the cat food.

Think right, provide good quality cat food and you will find that your cat poops surprisingly little.

A good example of this is obese cat food, which is heavily mixed with plant fiber in order to reduce calories and make it satiating.

As a result, cats that consume cat food for obese cats have unusually large stools. If your child's food is regular cat food, but the stools are coarse! In this case, it's time to revisit the quality of the food.



If it is red, anyone knows it is bloody stool, even if it is black there is blood in the stool. If the stomach bleeds the stool will turn into a soft black tar like stool.

There is also a lot of red coloring in the food, so be aware that completely red stools can form.

It is important to note that the color of your cat's stool should be the same color every time it is fed a particular food.

If you feed snacks and human food, then the shape and color of the stool will change every day and it will be hard to tell the difference.

Frequency of Pooping

  • Small Intestinal Diarrhea (relatively normal frequency)

With small intestinal diarrhea in cats, the frequency of stools does not increase much.

But it is easy to become watery stools and the amount of diarrhea that occurs at one time is large

Bleeding in the small intestine can lead to many serious diseases. In this case it is black to ketchup blackened stools.

Small bowel diarrhea is often associated with loss of energy and appetite.

  • Large bowel diarrhea (increased frequency)

Colonic diarrhea is more common when there is an increase in the frequency of stools. In the case of colonic diarrhea, mucus stools that look like jelly often appear.

Bleeding is easy to see because it is close to the "exit". "It's bloody stool!" However, bleeding caused by colonic diarrhea is generally not serious.

If a little bit of stool is frequent, it is very likely that the diarrhea is in the large intestine.

  • poses well, but no

Constipation goes without saying. There is inflammation in the large intestine, but there is no bowel movement, but the inflammation stimulates the urge to have a bowel movement, so there is a good posture, but there is no bowel movement.

The cause of constipation, it may be the prostate and perineum protrusion, etc., chronic case is best to go to the hospital.

  • decreased frequency

It is not certain that you are constipated even though the frequency has decreased.

If you are in a bowel movement position and if the stool does not come out, it is very likely that you are constipated.

In fact, if you don't eat, you won't have a bowel movement. Continuous loss of appetite, etc. can also lead to lack of bowel movement. Many people will worry that it is constipation, but there are many cases where it is not.

The color and smell of the urine

  • Light colors are more dangerous

Urine that is light in color always seems to be in good shape if you urinate a lot, but it's a trap. It is natural for urine to become light-colored if you overconsume water, but there are many cases where this is not the case.

The disease is represented by kidney failure.

As the kidneys fail, the urine cannot be concentrated and produces only light-colored urine, and a large amount of excretion results in a constant loss of water, so the animal becomes thirsty and wants to drink a lot of water again.

As an owner, you may think, "If you drink water, you will pass a lot of urine.

But in fact, the opposite is true: because urine absorbs water, you have to drink water. In this case, if you restrict water intake, thinking that "if you don't drink water, you won't pee," your cat will immediately become dehydrated and its condition will deteriorate.

Therefore, light-colored urine is something to be aware of.

  • odor

The foul odor of urine is easy to distinguish.

With diabetes, there may be a distinctive sweet odor. Hematuria can also have an iron odor of blood if it is strong.

If the bladder is paralyzed, the urine cannot be eliminated and will ferment inside the bladder to give off a foul odor.

  • Color

There are many cat owners who come to the hospital because of "strong colored urine". However, the dark color alone has nothing to do with the disease.

If the amount of water consumed is low, the urine will become thicker and the color will also become thicker.

After a lot of exercise, the amount of body fluids decreases with the exhalation of water, and with the mixing of pigments in the muscles, the urine looks even thicker.

There is no need to be concerned about this condition, the cat is fine, drink plenty of water.

But watch out for jaundice. It's also yellow, but it's a different shade like golden yellow. Double check the white part of the eyes if you feel confused, if it looks yellow it's jaundice, go to the hospital right away.

The color of urine is usually yellow. Anyone who is red knows that it is hematuria. Destruction of red blood cells can also cause red urine in cystitis and onion poisoning. In the case of light bleeding, on the other hand, the red color cannot be seen and most of it looks like tea color.

Frequency of urination

Many people bring their cats to the hospital saying they "can't pee".


  • Always feel like there is still (hard to urinate)

If you have cystitis, the inflammation can irritate the bladder, causing your cat to develop a sensation similar to the urge to urinate, always feeling like there is still residual urine.

In reality, the cat doesn't have any in the bladder, so it won't urinate and will just repeat the action of going to the toilet back and forth, one drop at a time.

It looks like the urine is blocked and won't come out, but it's not really that dangerous. Once the cystitis is cured, the number of trips to the bathroom will stabilize.

  • Really can't urinate (I'm blocked)

Male cats can have blocked urethra because of the long urethra, stones and blood and cell debris from cystitis.

This is a very serious problem.

If they are constipated, they won't die even if they don't have a bowel movement for two weeks, but if they can't urinate for 2-3 days, they will hang up due to UTI.

Occlusion is fine for 24 hours or less, but within 48 hours most will be in a dangerous state with UTI symptoms. Half will die if they don't make it out of 72 hours.

Bladder infections and urethral blockages are similar in that they both increase the frequency of trips to the toilet, so it's hard to tell the difference.

However, a blocked urethra is much more painful for the cat.

So, "Clogged?" , if it looks like it, then grab a hospital visit today or the next day.

Females have a thick urethra, so it's rarely blocked.

Finally... poop and pee are important health barometers.

Remember that we regularly check the condition of our cat's poop and pee, not to simply check the cat's poop and pee, but to perform a health check based on whether or not it is different than usual.
