Cat’s Urine Began to Smell Strongly: Causes and Treatment

Cats are animals that exist when there is a lack of moisture. They come from desert areas where water is a great value, so their body is “trained” by nature to make do with a small amount of it and save every drop. As a result, the animal’s urine is very concentrated and, as a result, has a pronounced characteristic smell.

This is a property of all domestic cats, so owners need to be prepared for such manifestations and clean up after their Pets more often. But a sudden and significant change in the usual smell indicates the appearance of serious disorders in the cat’s body, indicating the presence of pathologies or diseases.


In a healthy animal, the urine is yellowish in color, it is transparent, without inclusions, with a specific ” cat ” smell, with a predominance of sharp notes of ammonia. Changes can indicate both serious diseases and external causes:

Lack of water, dehydration

Although cats are used to minimal fluid intake, they can’t live completely without it. The situation may be aggravated by extreme heat, an abundance of dry food with insufficient clean water. As a result, very concentrated urine is released with a high content of urea and ammonia, which has a sharp smell.

Sex hormones

During puberty and rut, a large amount of hormones accumulate in the blood and urine of the animal, which give the urine an additional smell, especially pronounced in males. This is due to the fact that cats are territorial animals, and cats necessarily mark their territory and do this with the help of urine.

Eating disorders

If the cat’s food is dominated by protein, there are failures in protein metabolism, a lot of decomposition products and ammonia are released into the urine, the smell increases and becomes intense. The same disorders may occur when feeding an animal one type of food, such as high-protein chicken and fish, or using cheap low-quality feed.

Pathologies of the genitourinary system

These diseases can be hereditary or arise from various causes: neoplasms, infections, severe hypothermia, violations of salt and protein metabolism. Urolithiasis is especially susceptible to cats because of the structure of the genitourinary tract. The presence of inflammation significantly worsens the smell of urine.

Tumor processes can also provoke changes in the composition and smell of animal secretions.

Cats, like humans, can suffer from endocrine disorders, such as thyroid abnormalities or diabetes. As a result, their urine gets a characteristic sweet smell.


Stress causes disorders in all organs, and this easily affects the condition of the kidneys, so the smell becomes more concentrated. This is often the result of moving or changing the owner, which the cat tolerates with difficulty.

Any change in the cat’s secretions should cause concern, even if it is not triggered by the disease. Problems with poor nutrition or stress will eventually lead to the development of the disease, and this should not be allowed.

Accompanying symptoms

When there is an unpleasant smell of urine that differs from the usual one, the following symptoms are most often noted:

  1. When overheated, the cat breathes with its mouth open, like a dog, which is completely unusual for these creatures.
  2. Dry nose, hot ears, changes in the condition of the mucous membranes also indicate dehydration.
  3. The release of sex hormones during rut is accompanied by typical signs: a cat or cat is restless, they have dilated pupils, they scream, RUB against various objects, often seek to escape from home, and are especially active at night.
  4. When eating disorders often occur, not only an unpleasant smell of urine, but also a stench from the cat’s mouth, as well as obesity, problems with the chair, untidiness and lethargy.
  5. Diseases of the kidneys and urinary system are accompanied by pain and pain when urinating, urine droplets, frequent toilet visits, increased thirst, inflammation of the external genitals, in severe cases — apathy and loss of appetite.
  6. Tumors and endocrine disorders may not manifest themselves externally for a long time. Diabetes can be accompanied by severe thirst, obesity, and then a sharp loss of weight, with tumors, the behavior of the animal changes, nausea and vomiting may appear.
  7. Under stress, the cat tries to hide under the bed, sofa, wardrobe, any secluded place. Her eyes are dilated, and she may be trembling or clenching into a ball.

An attentive owner will immediately detect signs of danger and take the pet to a veterinary hospital.

Diagnostics in a veterinary clinic

In order to get accurate data, the cat will have to pass blood and urine tests, undergo ultrasound and radiography. Based on the examination, the owner’s survey and the received documentary data, the veterinarian will make a diagnosis and prescribe appropriate treatment.

Treatment method and prognosis

Treatment is always prescribed by a veterinarian after receiving a diagnosis, as there are many reasons for the change in smell. First of all, it is necessary to eliminate the factor that “started” the smell changes. If this is stressful, the cat needs to be provided with peace and allow it to adapt, treat it gently and calmly.

If you have problems with nutrition, you need to balance your diet and switch to the products recommended by your doctor. If the smell changes are caused by dehydration, the cat needs to ensure constant access to clean, fresh water. To do this, you can use special drinkers.

To avoid a strong smell, cats are neutered and cats are sterilized. With the loss of sexual desire within a few months, the release of hormones stops, and the smell of urine becomes normal.

Any disease is treated only by an experienced veterinarian after making an accurate diagnosis. Treatment depends on the type of disease, can be surgical or conservative, medication.

What to do at home

The main thing that a cat owner can and should do is to provide her with good care, warmth and love. Attempts to treat it on their own and “prescribing” human medications can cause the pet’s condition to deteriorate and even its death. The owner must strictly follow the instructions of the veterinarian.


Possible complications

Depending on which organ is affected, complications may occur in the cat’s disease. The most dangerous are the consequences of urolithiasis: blockage of the ureter or urethra, damage to the bladder, kidney failure.

Cats suffer from cancer, diabetes, Hyper-and hypothyroidism, that is, serious diseases peculiar to humans. If you do not start treatment in time, the consequences can be sad.

Prevention measures (diet)

It is important to feed the cat correctly, not to give him pieces from your table, especially sausage, smoked meat, fried, salted. His food should not be monotonous, you need to choose high-quality food, because saving on health will definitely lead to a problem.

Do not allow hypothermia cats, especially prone to kidney damage “bald” breeds, and, oddly enough, very fluffy. Purebred cats are more susceptible to diseases, as they have a weak immune system due to long-term selection.

If the owners take good care of their pet, they will be able to avoid problems with its health.
