Whether it is a cat’s urine or poop, it can more accurately reflect their physical condition. For example, if a cat’s poop becomes loose, it may indicate that there is a problem with the cat’s intestines, or it may be caused by other diseases. As for analyzing cat urine, in addition to observing its color, the health of the cat can only be judged by changes in its components. Therefore, if you want to detect the physical condition of your cat through urine, you need to use some related instruments.

Urine collection method

1. Natural urination: Increase the cat’s drinking water, promote its urination, and then take it. It is best to take it directly to avoid contamination.

2. Pressure on the bladder: However, this method is not recommended. For male dogs and cats, it is difficult to collect urine using this method. If trauma is present, compression of the bladder often results in an increase in red blood cells and protein in the urine sample. If the animal has urethral obstruction, has lost most of its bladder tissue, or has had recent major bladder trauma or cystotomy, compression of the bladder should not be used to collect urine. Excessive pressure can rupture the bladder, and a diseased bladder is more likely to rupture. Forcibly compressing the bladder to collect urine will cause urine to flow back from the bladder to the ureter, and inoculation of bacterially infected urine into the upper urinary tract will increase the risk of infection.

3. Catheterization: Catheterization should be performed under aseptic conditions as much as possible. Catheterization can avoid most contaminants in the vagina, penile foreskin, and perineum, but it is possible that an unclean urethral opening can contaminate urine. During catheterization, bacteria introduced into the bladder may cause infection of the otherwise healthy lower urinary tract in dogs and cats. The risk of iatrogenic bacterial infection is greater in those cases with pre-existing urinary tract infection. Pushing the catheter too hard can cause the diseased urethra or bladder to rupture. Operational errors can also cause normal urethra and bladder rupture. During catheterization, the presence of a wound will increase red blood cells, proteins, and epithelial cells in the sample.

Abnormal urine color

　1. Dark amber: highly concentrated urine, increased amount of bile pigment in urine

2. Red to dark reddish brown: complete red blood cells (hematuria), hemoglobinuria, myoglobinuria

3. Dark brown to black: most common when hemoglobin is converted into methemoglobin in acidic urine.

　4. Green: When bilirubin in urine is oxidized, biliverdin increases, Pseudomonas urinary tract infection, taking methylene blue

Abnormal appearance

　1. Cloudy or blurry: excess red blood cells, excess white blood cells, epithelial cells, bacteria or fungi

　2. Flocculation: white blood cell aggregation, epithelial cell aggregation, small stones or sand grains

Abnormal PH value

Under normal circumstances, catsThe pH of urine is usually acidic, but it ranges between 5.5-7.5. Persistent alkaline urine most often reflects infection of the urinary tract with urease-producing bacteria. Of course, it is normal to have alkaline urine for a period of time after eating.

Glucose detected in urine

There is no detectable amount of glucose in the urine of normal dogs and cats. Testing frozen urine samples can lead to false negative results and they must be warmed to room temperature before testing. Causes of diabetes: ① Diabetes is the most common clinical disease causing hyperglycemia and glycosuria. Hyperglycemia and glycosuria are sometimes associated with pancreatitis, hyperadrenocorticism, pheochromocytoma, and hypothalamic damage. ② Intravenous injection of sugar-containing liquids may cause hyperglycemia and glycosuria.

It is not that simple to test whether a cat’s urine is normal without relevant instruments. Therefore, if there are not enough conditions, it is recommended to send it to the hospital for examination to diagnose whether its physical condition is healthy.
