What are Urinary Crystals?

Urinary crystals are tiny or microscopic precipitants known to develop in the cat’s urine. The usual way to find the presence of urinary crystals in your cat is to visit a veterinarian and get a medical examination.

It starts with common issues related to the urinary tracts like urinating a lot, not urinating enough, or even having urinary accidents outside of their litter box.

To test out the presence of urinary crystals, your veterinarian would be required to run an in-depth urinalysis to find the presence of crystals or sediment in the cat’s urine.

How Do Urinary Crystals Develop?

There isn’t a single cause that leads to the development of urinary crystals. Instead, there are several variants of crystals & multiple reasons that your cat might experience this issue. The most common types of crystals that can be found in your cat’s urine are calcium oxalate and struvite. However, their prime reason for formation cannot be pinpointed.

Different crystals might develop inside your cat’s urinary tract if the cat fails to eat a proper, balanced, or complete diet. Additionally, any condition designated to change your cat’s urine pH, like a kidney issue or long-term use of medication, can lead to the development of crystals.

If you think it’s just the older cats that are affected due to urinary crystals, well, you might be wrong. These crystals can also affect young cats just as easily. It means age isn’t a major factor here.

However, it can be seen occurring majorly in older cats. Your feline partner’s unique physiology & disease history can help determine if there is a possibility for crystal development in the urine.

Additionally, crystals can also indicate the possibility of uroliths or bladder stones that are rock-like minerals that form in the cat’s bladder. However, you need to keep in mind that if a pet is diagnosed with the presence of crystals, it doesn’t necessarily mean that their kidney would show the presence of bladder stones.

Your cat would require an additional ultrasound and radiograph to determine whether these stones are present in their kidney.

Several factors might cause urinary crystals. One such factor is their diet. Your cat needs to consume a balanced and complete diet appropriate to its life stage. Make sure you check with your veterinarian and ask for a suggestion regarding food habits that help produce optimal urine pH levels.

Treating crystals often surfaces as a multi-pronged treatment approach. The first thing you need to do is to eliminate the possibility of any underlying cause. Most veterinarians recommend wet food from high-quality manufacturers as the canned versions tend to help reduce the presence of crystals.

Regardless of the type of food, it is evident that adequate hydration techniques are imperative for cats that refrain from drinking the required amount of water.

Why and How Do They Cause Pain?

Crystals found in the cat’s urine can cause Pain depending on the size and number. These urine crystals are generally shaped in the form of a hexagon & might also be colorless.

You can judge by the sounds your cat makes when they urinate that they are in Pain. Plus, you will often find that the cat is refraining from urinating regularly.

Symptoms of crystals in the urine can include:

  • Bloody urine
  • Vomiting
  • Nausea
  • Groin/back pain

Passing urine crystals can be painful, depending on how big they are. When bigger, they are termed kidney stones. However, the good news is, they do not cause any permanent damage when recognized early on.

Your vet would recommend that you try to make your cat drink more water to help clear out any crystals present in the urinary tract or the kidney, which could prevent the possibility of kidney stones. Cats have a small-sized urethra, and the presence of crystals can block and clump the urine flow.

Here are some more symptoms that denote the presence of crystals in the cat urine:

  • Straining during urination
  • Frequent genital licking
  • Chronic infection in the urinary tract
  • Urine spraying
  • Hematuria
  • Obstruction in the urinary tract (primarily in males)

What are the Health Threats of Urinary Crystals?

Generally, most cats get by well, even with urinary crystals ailing them. However, there could be cases that experience serious blockage in the urethra that requires urgent veterinary attention.

Some crystals amalgamate into the form of larger stones or sand-like grit that might get lodged in your cat’s urethra. It could lead to a potentially life-threatening issue that makes your cat incapable of passing the urine in any manner.

These minerals that bulk up inside the urethra and create blockages are generally a part of your cat’s dietary constituent. All living beings ingest minerals present in their food and metabolize the same. While they are necessary for cell function and metabolism, excessive of the same could lead to unwanted health complications.

In most cases, the excessive mineral automatically passes out of the body via urine. However, it isn’t easy to get rid of it if the urine is concentrated with excessive minerals present. If the acid-based balance in the urine is distorted, the minerals will get stuck together, forming crystals.

These crystals are mostly microscopic, but they can form a bigger mass and lead to blockages when one or more crystals come together.

Crystalluria can lead to disorders such as urethral obstruction and can even damage the cat’s kidney when left unchecked for long.

Which Food Ingredients help deal with Urinary Crystals?

Your veterinarian would suggest that you keep a check on your cat’s diet, especially if their food contains a lot of phosphorus, magnesium, & calcium. These minerals in high amounts can cause stone or crystal formation. The dietary change can vary depending on the type of crystal present in your cat’s urine.

The best way to go about it is to increase the water being fed to the cat. It will help dilute the urine and allow the crystals to move out of the body easily. First, however, you must notice whether your cat is urinating or not.

The method only works when your cat is urinating normally. However, it might not work well if the crystals block the cat’s urethra. It could also cause potential health hazards for your cat.

So, the key is to consult a veterinarian and get the issue resolved professionally. Cats are picky eaters and most generally won’t answer well to an abrupt dietary change. So, it would help if you introduced these changes slowly.

For example, switch from dry food to canned food because the latter contains a high amount of water compared to dry cat food.

You can also add flavors to your cat’s water, such as chicken-broth (sodium-free) or tuna juice, to tempt them into drinking more water.
