Why does my cat’s poop smell so bad?

Cat constipation
Why does my cat’s poop smell so bad? Let’s face it, this doesn’t mean it smells like a basket of roses, but if your kitten can clean the room after defecation, you may start to wonder if the cat’s feces smell more smelly than it should. This is knowledge about cats and their foul-smelling poop.
Diet problems

Just like humans, poor diet can cause stomach discomfort in cats.
Whenever possible, you should choose high-quality wet cat food. Wet cat food can provide more water and make the cat’s bowel movements easier. They also tend to contain fewer fillers, which means there are more digestible ingredients. Usually, the cause of the odor in the litter box is that the bacteria are digesting some of the food that the cat cannot digest. Likewise, if you take turns eating cats, be aware of which day seems to be the day with the worst litter box smell. It may be attributed to certain brands or tastes. A sudden change of cat food can also cause stomach upset.
Many serious diseases, such as chronic kidney disease, hyperthyroidism, diabetes, etc., have attracted people’s attention due to irregular waste.
In addition, parasites such as worms and certain vicious microorganisms can also upset your cat’s stomach and bring an unpleasant litter box experience. Choice of cat litter

After bringing the cat to the veterinarian, he or she has received a clean health sheet, and after consulting with the veterinarian, you can be sure that the cat is eating proper food. You may blame the litter box itself. Some cat litter smells worse than others. For example, natural plant-based garbage and odorless clay garbage often need to be completely replaced because they retain the smell. The problem may also be that your cat is not covering up the stool, which you can imagine will have the same effect as someone in your family who has never flushed the toilet.
Are you worried that the cat’s litter box will smell your apartment when you are away?

Cat Poop Clicker
In addition to the need to clean things from the litter box, the cat’s poop can also provide clues about its overall health. Petplan veterinarian Brian Faulkner here reveals the different appearances that pet feces can take-and what each animal can indicate. If any abnormal symptoms or signs persist for more than two days, it is always worth seeing a veterinarian to examine your cat. Perfect poop

The ideal shape of a cat’s poop is small, compact and oblong, although the length and number are usually related to the size of the cat. Brian said that its color should be dark brown, and in terms of texture, “it should look strong and strong, but not difficult.” Adult cats should pass feces once or twice a day, while kittens may pass it several times during the same period. Difficulty defecation

Your cat may pass two types of stool, and they may indicate constipation: small, hard, dry stool fragments, or longer, finer stool fragments. However, although bowel movements may be a sign of constipation, it is important to ensure that this symptom is not mistaken for other problems. Bryan revealed: “Sometimes it may seem that cats are having trouble defecation, but in fact they are trying to urinate.” ‘This is more common than constipation, especially among men.
Older cats may also struggle with unobstructed stools because their intestines lose their tone and cannot “pull” their stools-this is usually caused by a condition called the “big colon”.


“In veterinary medicine, we define it as abnormal stool that is firmer or less viscous than “ideal” stool,” explains Brian. ‘Owners sometimes think it’s not diarrhea, unless it’s like water, which is not the case.
If the consistency of yogurt is like mousse, it is classified as diarrhea. ’

Its color range is also ok.
Brian said: “Diarrhea can be any kind, from bright yellow or orange to brown, black or red.” However, if it lasts longer or looks like “tomato soup,” then the veterinarian must pay attention to this urgently,” he added. The most common cause of sudden diarrhea in cats is an upset stomach from what they eat. Brian Disclosure: “Especially young cats are more susceptible to infectious parasites than animals that tend to cause loose stools. “Dietary intolerance is also a reason.” ”


The smell of healthy cat feces should be mild, with almost no obvious smell. A smelly stool is usually a sign of stomach or intestinal problems-caused by digestive diseases or parasites caused by bacteria and poor diet. Brian said: “The digested blood also produces a unique metallic taste.” ‘Just a bad smell is nothing to worry about.
He added that when this odor occurs at the same time as other symptoms (such as changes in color or consistency), it usually becomes more noticeable and may indicate a problem. ‘It is thought that 80% to 90% of foreign bodies will pass through the intestines smoothly. However, sometimes they can cause blockages. ’

Finding fur in cats’ poop is nothing to worry about, because if you don’t treat it as fur plush, the hair they ingest from grooming will pass through their system and flow out with the feces.
However, the small white spots resembling rice grains are usually remnants of tapeworms (although sometimes difficult to find), and you should contact your vet.
Unusual colors

As mentioned earlier, color can be a useful indicator of a problem. Brian pointed out that black, red or very dark brown stools are “signs of digested blood.” ‘Your cat may have licked the wound, or it may change color just after giving birth. This may also be a sign of intestinal bleeding or ulcers, but this is relatively rare. ’

Stool may also appear in several other colors, from yellow to green to white.

Does wet food make cats poop smell?

Kitten diarrhea
Everyone who has ever walked through a trash can containing fresh feces knows the pungent and unique smell. All feces smell stinky, but cat feces are recognizable and very scary. Have you ever thought about the foul-smelling idea? No matter what species it is from, the stool will smell bad.
There are reasons to think that waste is like garbage to the body, it is something that cannot be used and needs to be removed. For similar reasons, the organic materials in our own kitchen trash can also smell. Once we screen the food and take out all the available ingredients, the rest becomes garbage. This is the role of the cat’s body on the diet.
His digestive tract absorbed the food, just as we unloaded the grocery bag when we started preparing meals in the kitchen. We sort the bags and list the items needed in the recipe.
We remove the ingredients from the packaging, discard them or cut off the stems from the product and discard them. Your cat has eaten a meal, and his body traverses the various components of the meal, sorts them, and discards food that is not needed in the cat’s metabolism and energy production diet.
Poop is very smelly. The odor may come from the components of the feces itself, because it releases ammonia, sulfur, nitrogen and other aromatic gases. All feces contain volatile compounds. Once the feces are excreted, they will be released into the air by the feces itself.
These depend on the composition of the diet itself. Nitrogen is the basic component of protein, and because cats are carnivores, they should consume more protein than many other animals. Bacteria also stinks.
When the bacteria in the intestine digest the usable part of the waste, even after the waste is removed from the body, it may produce an unpleasant smell in the form of gas release.

How cat poop should be
Well, the simple answer is because it is stool. Over the years, people have explained this with the same possible reasons: diet, digestive diseases or parasites. But was the smell really bad at that time?
Japanese researchers found the answer in a new study published this month in the Journal of Chemical Ecology. The terrible smell comes from sulfur compounds. For anyone who has ever smelled the bad luck of a badass, this shouldn’t be surprising.
Masao Miyazaki, associate professor of biochemistry at Iwate University in Japan and the lead author of the study, said that the specific source of this smell is an organic sulfur compound, similar to the pungent components in white wine. It is worth noting here that the smell of white wine is often compared with the smell of cat urine. (Despite the value for money, many wine lovers believe that the aroma of cat urine can help identify high-quality Sauvignon Blanc.) There are many odor components in cat feces, but the researchers were able to eliminate fatty acids and other unpleasant odor substances that are also contained in cat feces to find out the peculiar smell of feces. Cats. His team successfully determined the chemical structure of the substance as 3-mercapto-3-methyl-1-butanol (MMB), which is a derivative of cataline, which is a sulfur-containing substance found in cat urine.
Amino acids. It is found to be particularly high in the urine of intact male cats, is related to pheromones, and is believed to play a role in marking areas.
The level of MMB emission in the feces of men and women is different, and the level of MMB emission in feces of men is higher than that of women. Lead author Hayao Miyazaki concluded that their breakthrough discovery may lead to the further development of technologies aimed at reducing the odor of cat feces.

7 reasons for the smell of cat feces

Cat feces will suddenly start to smell like human defecation. This shows that something is wrong with your best friend.
From bacteria, diet to parasites, to serious health conditions, everything is fine. 1) Diet

Just like humans, cats are sensitive to certain foods or certain things found in certain foods. For example, your kitten may be sensitive to grains or foods high in vitamins.
Elimination diets can help you identify specific foods that are causing digestive problems in your cat, so that they “smelt” a foul smell. 2) Bacteria

Cats are naturally carnivores.
They prey on other small animals as food. Their natural prey drive can cause them to eat incorrect or unhealthy foods.
This is especially true if your cat spends a lot of time outdoors.
They can eat meat that has been infected with Salmonella or E. coli, which can cause digestive system discomfort, inflammation or a sudden smell of feces and diarrhea. 3) Drugs and hormonal changes

Certain painkillers and drugs that affect hormones can change the cat’s natural chemical balance. Depending on the duration of the chemical change, your cat may suddenly deodorize. 4) Digestive system diseases

Digestive diseases and related problems can cause severe damage to the cat’s gastrointestinal tract, just as it does to humans. The result will be a strong pungent odor, usually very smelly. Most problems in the digestive tract are usually caused by poor digestion and absorption of starches and fats.
They are often discharged through glands. However, sometimes they become clogged and require manual drainage. If the glands are infected, your cat may have a runny nose, smell bad, and litter boxes are everywhere. 6) Foods rich in protein

Cats are naturally carnivores. This means that their food is usually rich in protein, especially the animal protein they source from the outdoors. As a result, the cat’s diet is high in protein, making the feces that it defecate emits a frightening and unpleasant smell.
Although you can’t do anything about the smell of cat poop, changing your diet can do wonders. 7) Parasites

Parasitic infections can upset your cat’s stomach, causing severe diarrhea and stools. They smell so bad that you have to go to the veterinarian.
Coccidia and trichomoniasis are some parasites that usually cause serious problems in animals, including cats with a foul smell.

According to any veterinarian’s information you request, after determining your cat’s sensitive food, restart the diet and routine feeding to ensure the cat’s health. Make sure to consult a veterinarian to help you develop proper diet and feeding habits for your cat.

Sometimes, as the cat’s digestive system adapts to the new eating habits, this problem will resolve itself. If the odor problem persists for more than 48 hours after the diet change, be sure to consult a veterinarian. 2. Bacteria

If your cat’s food is contaminated with bacteria such as E. coli or Salmonella, it may cause bad stools, indigestion, inflammation and diarrhea. Some cats like to hunt for food (even if they don’t need it!), and eating rodents or birds may put them at risk of bacterial infection.
Solution: If the cat’s stool smell has not returned to normal after 48 hours, consult a veterinarian. 3. Parasites

Certain types of intestinal parasites can cause excessive gas, diarrhea and smelly stools.

Make sure your kitten eats high-quality, balanced food suitable for its age and development, and avoid sudden or sudden changes in diet. This will help ensure that their diet is the most likely cause of the problem and ensure that you do things in the best way. worm

Parasitic worms are another possibility, especially if your kitten has been infected with worms before. Sometimes this can be indicated by symptoms such as weight loss and diarrhea, a large amount of infestation may cause bloating in kittens.
However, obvious symptoms do not always appear, and vague symptoms do appear. If you suspect that your kitten may have picked up the worm, talk to your veterinarian about the deworming procedure. infection

Gastrointestinal infections are another potential cause of stool changes, and if your kitten is also usually unwell, you are more likely to suspect this change.
