What Can Cats With Urinary Crystals Eat?

Cats can sometimes develop urinary crystals, which can lead to painful and potentially life-threatening urinary tract blockages. One way to help prevent the formation of crystals is through diet, as certain types of food can increase the risk of crystal formation. If your cat has been diagnosed with urinary crystals, it’s important to feed them a diet that is specifically designed to prevent the formation of these crystals.

Here is a list of what cats with urinary crystals can eat:

  1. Wet food: Wet food is generally more beneficial for cats with urinary crystals than dry food. This is because wet food is typically higher in moisture content, which can help keep your cat’s urinary tract hydrated and flush out any excess crystals. Wet food is also usually lower in ash, which is a mineral that can contribute to the formation of crystals.
  2. Low-ash, low-magnesium food: It’s important to choose a cat food that is low in ash and magnesium, as these minerals can contribute to crystal formation. Look for a food that is specifically formulated for cats with urinary issues, as these will often be lower in ash and magnesium.
  3. High-protein food: Cats with urinary crystals may also benefit from a diet that is higher in protein. Protein can help reduce the risk of crystal formation by increasing the acidity of your cat’s urine.
  4. Canned pumpkin: Canned pumpkin is a great natural option for cats with urinary crystals. It is high in fiber, which can help keep your cat’s urinary tract healthy and reduce the risk of blockages.
  5. Water: It’s important to make sure your cat is getting enough water, as proper hydration can help prevent the formation of crystals. Consider using a water fountain to encourage your cat to drink more, and consider adding a small amount of water to their wet food to increase their intake.

Any changes to your cat’s diet should be done gradually and under the guidance of your veterinarian. They will be able to recommend the best diet for your cat based on their specific needs and any underlying health conditions.

In summary, cats with urinary crystals can benefit from a diet that is high in moisture, low in ash and magnesium, high in protein, and supplemented with canned pumpkins. Proper hydration is also key in preventing crystal formation. Work with your veterinarian to determine the best diet for your cat and monitor their progress to ensure they are receiving the proper nutrients to maintain a healthy urinary tract.
