Frequent urination and thirst are one of the first messengers of kidney failure in cats. But these same symptoms are also characteristic of other diseases, therefore, a correct diagnosis is possible only on the basis of the results of a biochemical blood test. If there is increased urea in the blood, the cat is more likely to have abnormalities in the excretory system, and an increase in glucose concentration indicates problems with the pancreas and the risk of diabetes.
Causes of Increased Blood Urea in Cats
The processing of protein in the body of a mammal leads to the production of such a complex toxic compound as ammonia. In the process of its decay, carbonic diamide is formed in the liver (the traditional name for the compound is urea or urea). This compound has a less toxic effect, easily penetrates through cell membranes, is readily soluble in water, and normally leaves the body with urine almost completely.
Elevated urea in the blood of a cat may be due to the following factors:
- too much protein in your diet
- violations in the digestive tract,
- dysbiosis due to the use of stale or spoiled foods,
- ulcerative and other processes in the intestines or stomach, leading to internal bleeding in them,
- poor kidney function.
Recognition of renal failure in cats
Restless behavior of the cat, loss of appetite, in some cases vomiting, too frequent, or, conversely, rare and painful urination - all this can indicate interruptions in the work of the kidneys, as well as other problems with the pet.
To find out the presence of impaired renal function in a pet is possible only with a comprehensive diagnosis. The determination of urea in the blood is one of the important alarm signs.
The first step is to check the level of urea.
Such indicators of the level of urea in the blood are considered to be normal: for dogs 24 - 36 mg per dl. (4 - 6 mmol per liter) and slightly higher for cats 36 - 72 mg per dl. (6 - 12 mmol per liter). Depending on the equipment used in the laboratory, the standards may vary slightly.
Since urea is the end product of the breakdown of protein amino acids consumed with food, and cats - predators and proteins make up a large part of their diet, an excess of protein food sometimes causes the change in the concentration of this compound in the animal’s blood.
Errors in nutrition, and in some cases intestinal dysbiosis of various etymologies, can lead to an increase in urea concentration up to 120 mg per dl. (20 mmol per liter) with absolutely healthy kidneys. In renal failure, necessarily high urea is also accompanied by an increase in the level of creatinine in the blood of the cat.
An important marker of kidney failure is creatinine.
Another end product of protein metabolism in the body is creatinine, which is secreted into the bloodstream from the muscle tissue where it forms. It is also excreted, like urea, with the participation of the kidneys. The cause of high creatinine in the blood of a cat may be cirrhosis of the liver, gall bladder disease, or dehydration.
Normal creatinine levels in cats are characterized by levels ranging from 240 to 780 mg per dl. (40 - 130 mmol per liter), they may vary slightly for different laboratories. The critical concentration of the compound is from 250 - 300 mmol per liter, which corresponds to 1500 - 1800 mg per dl.
Prevention of renal failure in cats and cats
According to statistics, in general, kidney problems such as acute or chronic renal failure and urolithiasis are found in 25% of domestic cats. For animals that have undergone sterilization, the risk is almost doubled. In the high-risk group and some breeds of cats - for Persians, urolithiasis is recognized as a breed disease.
Often the cause of high levels of urea in the blood of cats and cats, and as a result of kidney problems, are errors in nutrition and care. To timely detect the development of a disease state, you need to follow simple rules:
- prevent dehydration,
- diversify the diet,
- do not save on dry food, as the colorants and aromatic compositions contained in cheap options are extremely harmful to the kidneys and liver of a cat,
- examine a pet at least once a year, animals older than 10 years - once every 6 months.
The detected increase in the concentration of urea and creatinine in the cat’s blood in the initial stages of the disease allows either to completely cure the animal, or to correct its condition. With proper care and diet, the life expectancy of cats and cats with a chronic form of renal failure is practically not reduced.
