Our Sonora veterinarians frequently encounter cats experiencing distressing symptoms associated with bladder stones. In this discussion, we explore how the symptoms of a bladder infection in cats can indicate the presence of bladder stones.
What Causes Bladder Stones In Cats
Bladder stones can begin to form when excessive amounts of certain minerals in your cat's urine begin to clump together with other substances found in the bladder. Bladder stones may be caused by a number of factors including:
Medications or supplements
Dehydration
Poor diet
Breed predisposition
Congenital liver shunt
Medications or supplements
Bladder or urinary tract infection
Bladder inflammation caused by crystals
Extremes in urine pH levels (too alkaline or acidic)
Overweight male cats may face an increased risk of developing bladder stones.
Types of Bladder Stones Seen In Cats
The 2 most common types of bladder stones seen in cats are calcium oxalate and struvite stones.
Calcium Oxalate Stones
Calcium oxalate stones typically develop in cats with urine that is highly acidic. It is also common to see calcium oxalate stones in cats with high urine and blood calcium levels. Cats suffering from chronic kidney disease can also develop these kinds of bladder stones.
These stones are most often seen in cats between 5 and 14 years old.
Struvite Stones
Struvite stones appear in cats with highly alkaline urine. This can be the result of a urinary tract infection but it's not always the case. These bladder stones are often seen in cats who consume high amounts of magnesium, phosphorus, calcium, chloride and fiber.
A genetic factor may also influence a cat's risk of developing struvite stones since Siamese cats appear to be predisposed to developing struvite stones.
Signs of Bladder Infection In Cats
For cats, symptoms of bladder infections in cats are similar to the symptoms of bladder stones. Keep in mind that signs of bladder infection in female cats can appear differently in male cats. This is due to the irritation caused within the bladder due to the stones. If your cat is suffering from bladder stones you may notice one or more of the following symptoms:
Blood in urine
Frequent urination in small amounts of urine
Painful or difficult urination
Urinating outside the litter box
Abdominal pain
Lack of energy
Straining to urinate without producing urine
Bladder stones can lead to a urinary obstruction in cats which is considered a medical emergency! A urinary obstruction occurs when your cat's urethra becomes blocked with a stone and your cat is unable to pass urine. Signs of urinary obstruction include:
Vomiting
Abdominal pain
Repeated trips to the litter box
Yowling or crying while in the litter box
Straining to urinate without producing urine
If you notice any of these symptoms associated with a urinary obstruction contact your vet immediately or visit your nearest emergency animals hospital for urgent care.
Treatment For Cat Bladder Stones
The best treatment for your cat's bladder stones will depend upon the type of stones that your cat has. Some types of bladder stones, including struvite stones, can often be dissolved with the help of a therapeutic diet and medications.
Calcium oxalate stones cannot be dissolved and are typically treated with cystotomy surgery to open the bladder and remove the stones. This surgery has an excellent success rate and most cats recover from surgery very quickly.
Preventing Bladder Stones From Occurring In Cats
It may be possible to prevent your cat from developing bladder stones. If your cat is a breed that faces a higher risk of developing bladder stones you may want to try the following:
Ask your vet to recommend a food to help minimize your cat's likelihood of developing crystals that could lead to bladder stones.
Ensure that your cat always has easy access to fresh clean water.
Make sure that your cat gets plenty of exercise.
Keep your cat's litter box clean to encourage your cat to urinate when they need to and not wait.
Feed your cat wet food to help ensure that they are adequately hydrated. Good hydration can help to continually flush crystals out of your cat's bladder and prevent a buildup.
Speak to your vet before giving your cat any nutritional supplements, particularly supplements containing calcium, vitamin C or vitamin D.
