What is Blood in the Urine?
Veterinarians use the word hematuria to describe blood in your cat’s urine. Females are more likely to develop this condition than males. Blood in the urine can be a sign of infection, a hereditary condition, or a more serious health issue.
If your cat develops a problem in the urinary tract, you may see some blood in his urine. This can be a sign of a mild condition or it may be a symptom of a more serious, underlying condition.
Symptoms of Blood in the Urine in Cats
The symptoms associated with blood in the urine depend on the cause of the condition. Here are some of the most common symptoms that can accompany blood in your cat’s urine:
- Red colored urine
- Passing urine more frequently than normal
- Red, raised patches on the skin
- Palpable mass in cats who have tumors
- Pain when urinating
- Licking of urinary area
- Odor of ammonia in urine
- Prolonged squatting or straining while in the litter box
- Avoiding the litter box
- Urinating in unusual places inside
- Distended abdominal area
- Excessive thirst
There are several different types of conditions that could cause your cat to have blood in his urine. Some of the most common are:
- Diseases of the endocrine system
- Conditions of the urinary tract
Causes of Blood in the Urine in Cats
A variety of conditions can cause hematuria to occur. They range from mild to very serious and include:
- Abnormality of the urinary tract
- Parasitic infection
- Blood clotting disorders
- Cancer of the urinary tract that may occur with tumors
- Kidney stones
- Idiopathic, or of unknown origin
Diagnosis of Blood in the Urine in Cats
Your veterinarian will need information from you before examining your cat to determine the cause of hematuria. He will begin by asking you some questions about your cat’s health and behavior. Be sure to give as much information as possible regarding your cat’s birth history, pre-existing medical conditions and trauma that may have occurred. Your doctor will also ask you when the symptoms first started and if they have increased in severity recently.
After taking a medical history, your doctor will examine your cat. A blood sample will be taken from your cat, as well. A CBC, or complete blood count, biochemical profile and urinalysis will be run at this time. Your veterinarian may also use a strip to determine if red discoloration in his urine is actually blood.
Diagnostic tests such as in-house X-rays may be used to diagnose the cause of hematuria in cats. An ultrasound may also be performed to provide additional information, depending on what your doctor suspects the problem may be. A CT scan with contrast dye may also provide a detailed picture of your cat’s urinary tract. If your doctor palpates a mass in your cat’s abdomen, he may want to schedule a biopsy. During this procedure, he would take a small tissue sample of the tumor and send it to an outside laboratory. This is the procedure used to determine if the tumor is benign or malignant.
Treatment of Blood in the Urine in Cats
It is important to treat the cause of hematuria as soon as possible to avoid serious complications. Cats that have blood clotting diseases can lose a great deal of blood in a short period of time. Conditions such as kidney stones can completely obstruct the bladder and cause it to rupture. This is a life-threatening situation for your pet.
The treatment for blood in your cat’s urine depends largely upon the condition causing it. If infection is causing hematuria, your veterinarian may place your cat on antibiotics until the infection clears. Cats that are dehydrated or unstable will be treated with IV fluids. Conditions causing blood in your cat’s urine such as diabetes or endocrine diseases must be treated accordingly to clear hematuria. Cats that have been on medications such as steroids that are causing blood to appear, will be taken off those medications gradually. It is dangerous to stop some medications quickly, so your doctor will wean your cat from them. In some instances, this is enough to stop hematuria from occurring. If your doctor finds kidney stones or tumors in the urinary tract, surgery may be recommended.
Recovery of Blood in the Urine in Cats
Your cat’s recovery will depend on the cause of the condition and the treatment your doctor prescribes. It is important to attend all follow-up visits if necessary, give your cat all prescribed medications and report any negative changes in his condition to your veterinarian. With prompt diagnosis and proper treatment, many cats go on to recover from blood in the urine. Certain conditions may require ongoing treatment and management, but it is well worth it if your cat goes on to lead a happy, long life.

I took my cat to the vet this morning as she was constantly visiting the litter tray. She was passing small amounts of urine with blood. She comes off the litter tray and wipes herself on the carpet, then licks her genitals.
After being given an injection of a 14 day anribiotic she is visiting the tray less often but still has bloody urine and is licking.
How long will it take for the bleeding to stop and the antibiotic to take effect,

I have a 16 year old indoor car who's in good health.
She does have hyperthyroidism, which is on treatment with topical Tapazole.
She has had hematuria for about 7-8 months now, and 3 vets haven't been able to help.
We have tried special food, anti inflammatories and antibiotics.
Generally blood in the urine is caused by infection, inflammation, stones, trauma, kidney disease or tumours; in cases of hyperthyroidism, there is an increase in blood flow to the kidneys which may rupture a capillary here or there. I assume urine samples have been taken for culture and sensitivity as well as general urinalysis; if there are no other symptoms, I wouldn’t put too much stress on the bleeding, an x-ray may show a lesion.
