What are Kidney Stones?

Kidney stones don't typically present symptoms until they grow large, irritating the kidney ducts and potentially causing a serious infection or obstruction. Male cats and domestic Shorthairs are more likely to develop kidney stones than females and other breeds of cats.

The kidneys are responsible for filtering the blood, removing wastes such as mineral salts, urea, and toxins, and excreting these filtered wastes with water in the form of urine. Some of these wastes that are normally excreted by the kidneys aren't completely soluble and remain in the kidneys, forming crystals or renal calculi. Over time, these crystals can form stones, known as nephroliths, and cause a condition known as nephrolithiasis.

Symptoms of Kidney Stones in Cats

Small kidney stones often don't present symptoms and only become detected during a diagnostic test for another medical issue. Once kidney stones grow, however, they may cause the following symptoms:

  • Vomiting
  • Loss of appetite
  • Bloody urine
  • Painful urination that is difficult to pass
  • Abdominal pain
  • Frequent urinary tract infection
  • Frequent urination that only produces a small amount of urine

Causes of Kidney Stones in Cats

There are approximately ten different types of minerals that can form stones. Each type of kidney stone can be attributed to different causes. Some of these causes include:

  • Underlying kidney infection
  • Underlying urinary tract or bladder infection
  • Increased calcium levels in blood and urine
  • Supplements or diets that produce urine with a high alkaline pH
  • Genetic defects
  • Dehydration
  • Urinary retention
  • Certain medications
  • Certain concurrent illnesses or conditions

Diagnosis of Kidney Stones in Cats

The veterinarian will need to know the cat's complete health history, which will include a list of symptoms, any recent illnesses or urinary tract infections, and any recent changes to the cat's diet. The veterinarian will physically examine the cat and draw several labs, which will include a complete blood count, a biochemical profile, a urinalysis, and a bacterial urine culture. These tests can indicate any other organ systems that are being affected, other concurring illnesses or conditions, the presence of a urinary tract infection, and the type of bacteria that is present in the urine.

X-rays and ultrasounds will also be done. These tests can show the presence of stones in the kidneys. In order to correctly identify the stones, a procedure called extracorporeal shock wave lithotripsy (ESWL) may be performed. During this noninvasive procedure, shock waves will be used to break up the stones, allowing pieces to be removed from the urinary tract and identified. Identifying the minerals in the stones can help determine the best treatment for the cat.

Treatment of Kidney Stones in Cats


If the kidney stones aren't obstructing the flow of urine, the cat may be prescribed medication in order to dissolve the stones, allowing them to pass from the cat via the urine. The urine culture will identify any bacteria present in the urine and an appropriate antibiotic will be determined and prescribed in order to treat cats with urinary tract infections. Medication for pain will also be given to the cat in order to reduce their pain levels while treatment for the kidney stones occurs.

Fluid Therapy

Cats who are dehydrated will need to be admitted to the hospital in order to receive fluid intravenously. The veterinarian will monitor the kidneys and heart during fluid therapy to ensure the fluids are being properly received by the body.


Stones that are obstructing the flow of urine will need to be removed promptly in order to prevent kidney failure from occurring. Extracorporeal shock wave lithotripsy (ESWL) is typically the first option used by veterinarians for the removal of kidney stones due to its noninvasive nature.


If the kidney stones are posing a medical emergency and ESWL isn't effective, surgery may be needed. During surgery, the veterinarian will make a small incision into the kidneys with the guidance of an ultrasound in order to remove the stones that are obstructing the flow of urine. The incision will be closed with sutures and the cat will remain in the hospital where it will be monitored. Surgery poses the risk of infection and of causing kidney damage, so it is only used when other treatment options aren't working.

Recovery of Kidney Stones in Cats

Kidney stones tend to recur, so routine monitoring via ultrasounds will be necessary. If the cat received surgery, a follow-up appointment will be necessary in order for the veterinarian to check the incision site for infection. The veterinarian may recommend dietary changes, such as feeding the cat a diet of 50 percent wet food. These dietary changes can help reduce the cat's risk of developing kidney stones. Ensuring the cat always has a fresh supply of water can reduce the risk of dehydration and stones forming again.

Has Symptoms


One week ago my cat started having seizures. After testing her brain MRI and spinal tap are negative. Other findings were high urine protein and a kidney stone. The kidney stone in her right ureter is causing hydronephrosis of her kidney. They want to do surgery either remove stone or bypass surgery.

If there is a urinary stone in the ureter and one kidney is becoming enlarged by hydronephrosis then surgery is indicated in this case to either remove the stone or even the kidney if necessary. Seizures wouldn’t be directly related to the urinary tract issues unless there was a decrease in overall kidney function but this would be ruled out by blood test. You should have the surgery done, discuss with your Veterinarian. Regards Dr Callum Turner DVM

Has Symptoms

lack of appetite

I took my cat to the veterinary this week because he was lethargic and stopped eating. They did an x-ray and ultrasound and found one stone in each kidney. The left kidney is much bigger than the right one and has the bigger stone. In the blood test, his urea was high and also other parameters. He has been taking antibiotics, painkillers and receiving intravenous fluids at the clinic during this week.He is much better but the parameters in the blood are still not in the proper range. The clinic suggested a surgery but they don't know which kidney is working. So they would open him, and plan A is to remove the stone from the left kidney. If the kidney is blocked and full of urine, they would remove the whole kidney. After the surgery, if the right kidney works, then he could recover, if not he would die. Its is a very risky operation. Are there any safer methodologies to remove the stone from the kidney? Is there any exame to study which kidney is working? When is surgery the last option? Appreciate if you can help.

It is possible that the left kidney has its pelvis (renal pelvis) blocked by the stone and removing the stone may help with the flow of urine into the ureter; I would recommend an intravenous pyelogram which would indicate which kidney is functioning (hopefully both). After the intravenous pyelogram your Veterinarian and yourself can be more confident going forward with surgery to remove the kidney if required. Regards Dr Callum Turner DVM

Good Afternoon,

I took one of my four cats in to see the veterinarian concerning a litter box issue where the focus had been a blood test taken to see if there was a health issue behind all this. However, when the examination was done, the veterinarian noted the cat's reaction [muscle twitching and spasms on her back when being petted by him] and I was talked into having an x-ray taken rather than the blood test as I had originally come for. The x-ray showed a spot near the left kidney and he prescribed a pain medication due to those x-ray results and his examination of Zoellie. Other tests were mentioned by the cost was too high for the moment. She loved a treat, freeze-dried shrimp! Could this be contributing to the forma5ion of kidney stones? She is only 3 and a half years old and not middle aged or older. Any thoughts?

If Zollie has kidney stone, your Veterinarian would have mentioned specifically that there are kidney stones and would have recommended dietary changes and would have taken a urine sample to determine the type of crystals present. A spot on the kidney may be due to various conditions some of which may include cancer; without an examination, urinalysis and blood tests I cannot really help narrow this down. However, you should start looking into a renal diet to reduce any stress on Zollie’s kidneys. Regards Dr Callum Turner DVM

My mother recently got a kitten. She’s been screaming when she Urinates. We believe it’s kidney stones. We also have not much money. How do we take care of her pain without spending too much money and making sure she doesn’t get hurt?

Dr. Callum Turner, DVM

There are various causes for urinary difficulties in kittens which may include stone, infections, congenital issues among other causes; without examining Clarissa I cannot confirm a cause. It is important to keep her hydrated, plain Pedialyte can help with that; but ideally an examination by a Veterinarian would be best along with vaccinations too. Regards Dr Callum Turner DVM
