How To Dissolve Struvite Crystals In Cats Naturally

Struvite crystals in cats occur when the urine becomes too concentrated, causing urinary tract infections (UTIs). The crystals, a type of mineral deposit, are made up of magnesium, ammonium, and phosphate. Struvite crystals can cause symptoms similar to a UTI, such as frequent urination, and may even block the cat’s urinary tract. Dissolving struvite crystals in cats naturally is possible by using dietary adjustments and simple home remedies. These solutions can eliminate the presence of crystals, reduce the risk of future infection, and make the immaculate feline urinate more comfortably.

What Is Struvite Crystals?

Struvite crystals are a type of mineral salt found in urine due to a combination of high pH, high ammonium, and high phosphate levels. Struvite tends to form hard crystals that range in size from large ones being several millimeters in length, to small ones that are barely visible. Struvite can be a sign of a urinary tract infection (UTI) or even more serious conditions. If left untreated, it can lead to bladder stones, bladder irritation, and even serious infection. When struvite is first noticed in a urine sample, immediate action should be taken to treat and prevent the spread of infection. Treatment typically consists of a course of antibiotics and possibly other interventions, depending on the underlying cause. The main goal is to reduce the risk of infection and reduce the number of struvite crystals present in the urine.

How To Know If Your Cat Has Struvite Crystals

Struvite crystals are small stones made of magnesium ammonium phosphate that form in a cat’s urinary tract. Signs of Struvite crystals in cats can include frequent urination, difficulty urinating, bloody urine, straining to urinate, and painful urination. To diagnose if your cat has Struvite crystals, your vet will conduct a physical exam and take a urine sample or do an ultrasound. Urinalysis can detect crystals within the urine, and an ultrasound can detect any stones present in the bladder or urinary tract. Once Struvite crystals are diagnosed, your vet will recommend appropriate treatments based on your cat’s symptoms and medical history.

Symptoms Of Struvite Crystals In Cats

Struvite crystals in cats are a type of mineral that form in a cat’s urine when it has an increased level of magnesium, ammonium, and phosphate. Symptoms of Struvite Crystals In Cats include:

  • Painful Urination: Struvite crystals can cause inflammation of a cat’s bladder and urethra, causing frequent and painful urination. Cats may strain to pass urine or pass it in small amounts often.
  • Excessive Licking of Genital Area: Crystal formation blocks a cat’s urethra, which can make urinating uncomfortable. As such, cats may lick their genital area frequently in an attempt to make it more comfortable.
  • Blood in the Urine: Struvite crystal can cause damage to the lining of the urethra, leading to the presence of blood in the urine.
  • Abnormal Drinking Habits: Struvite crystals can reduce a cat’s ability to concentrate its urine, leading to an increase in water consumption.
  • Abdominal Pain: The bladder and urinary tract can become irritated due to Struvite crystal formation, and this can cause the cat to experience discomfort in the abdominal area.
  • Changes in Urination Behaviour: Struvite crystals can block the urethra, making it difficult for cats to pass urine, resulting in infrequent and difficult urination, or excessive urination.

Calcium Oxalate Crystals: These are smaller, angular crystals and are made up of calcium oxalate and phosphate. They can often be found in cats who have lower urinary tract disease or calcium imbalances.

Struvite crystals: These are a type of mineral deposit that can form in the urine of cats. They are composed of magnesium, ammonium, and phosphate, and can cause issues in the bladder, urinary tract, and kidneys.

Causes Of Struvite Crystals In Cats

Struvite crystals in cats are caused by a urinary tract infection (UTI) caused by bacteria that produce an alkaline urine pH level. Struvite crystals form when the urine has a higher alkaline level than usual, and when the size and shape of the crystals are not conducive to dissolving in the urine. These crystals can be an indication of a urinary tract infection.

The most common cause of struvite crystals in cats is a UTI caused by bacteria, such as Staphylococcus or Proteus, which are naturally occurring organisms in the digestive tract of cats that can travel to the bladder. When the bacteria are concentrated in the bladder, they can create an environment where pH levels become too alkaline, which can allow the formation of struvite crystals.

In cats, struvite crystals may also be caused by conditions that cause a decrease in water intake, such as kidney disease, diabetes, or over-supplementation of foods that are low in water content. 

Lastly, struvite crystals can form in cats due to dietary imbalances. Diets that are high in magnesium and phosphorus can cause an increase in struvite crystal formation. Low-quality protein sources, including grains, can also lead to struvite crystals in cats.

Treatment Of Struvite Crystals In Cats

Struvite crystals form from magnesium, ammonium, and phosphate, which are all components of urine. In cats, these crystals form bladder stones or other types of crystalline masses which can be very uncomfortable and even cause obstruction of the urinary tract. Fortunately, there are ways to treat struvite crystals in cats.

One of the primary treatments for struvite crystals in cats is the administration of a prescription diet known as an acidifying diet. This type of diet helps lower the pH of the urine, making it more acidic. This acidic environment helps to dissolve existing crystals and reduce their recurrence. Cats on this type of diet should be monitored closely by a veterinarian to ensure that they are maintaining a healthy pH, as an overly acidic diet can cause other health issues.

Other types of treatments can include antibiotics to treat any existing infection, as well as increasing water intake to help dilute the urine. Your veterinarian may also recommend supplements, such as potassium citrate or thiamine, to help manage the urinary pH. 

In addition to these specific treatments, it is important to ensure that your cat has an overall healthy lifestyle. This includes plenty of exercise, access to clean water, and a balanced diet. By helping your cat maintain a healthier lifestyle, you can reduce the risk of struvite crystals occurring in the future.

How To Dissolve Struvite Crystals In Cats Naturally (Home Remedies)

Natural remedies can be used to dissolve Struvite crystals in cats naturally. Some of the home remedies to dissolve Struvite crystals in cats include:

Increasing the water intake: Increasing the water intake of your kitty is very important. This is because adequate hydration will increase the amount of urine, which is important for the proper breakdown and dissolution of the crystal. You can achieve this by adding water-rich food such as tuna or other wet cat foods, bathing twice or thrice daily, or using a water fountain.

Increasing the amount of vitamin C in your cat’s diet: Vitamin C is essential for the breakdown of Struvite crystals. You can increase the level of Vitamin C in your cat’s diet by adding supplements or feeding foods rich in Vitamin C like strawberries, oranges, etc.

Diet modification: Changing your cat’s diet is an essential part of dissolving Struvite crystals. Feeding your cat a diet low in magnesium and phosphorus is essential to help dissolve these crystals. This diet should also be low in protein and low in acid. Since cats are carnivores, they require a certain amount of animal-based proteins in their diets. Consider a diet with a high proportion of fresh meats or meat-based wet cat foods.

Herbal remedies: There are certain herbs that can help aid in the dissolution of Struvite crystals. These include Marshmallow root, Corn silk, Uva Ursi, and Goldenseal. These herbs are known for their ability to reduce inflammation and assist in breaking down crystals naturally.

By following these natural remedies, you can dissolve and prevent Struvite crystals from forming in your cat.
