The Best Low Magnesium Cat Food Reviews













The best low-magnesium cat food makes caring for cats with urinary tracts easier. Here are my five picks:

#1. Purina ONE High Protein Dry Cat Food – Best For Overall

Editor’s Ratings:

Brand: Purina ONE | Form: Dry Food | Flavors: Chicken | Life Stage: Adult

What We Liked:

– Real chicken flavor;
– Support urinary tract health with a low magnesium content;
– Support the immune system with antioxidants;
– No artificial colors or flavors.

What We Didn’t Like:

– Have only chicken flavor.

Product Highlights

Coping with my cat’s urinary tract problems is always a constant concern, but this Purina ONE cat food has proven to be a game changer in maintaining their health.

The key feature of this cat food is its low magnesium content, which plays a role in supporting urinary tract health. 

Lowering the pH in the urine helps prevent the formation of urinary crystals and stones, often associated with urinary tract infections (UTIs) and blockages.

I have tried different brands, but my cats didn’t like them, often refusing to eat until they were starving. With Purina ONE, however, they eagerly ate their meal right away and seemed to enjoy it.

This cat food puts my mind at ease, knowing they are getting the nutrition they need to maintain a healthy urinary tract. Also, it has effectively prevented UTIs in my two other cats.

To enhance the benefits, I occasionally supplement their diet with a wet food specifically designed for urinary tract health. 

This combination has proven to be a winning formula for my cats, reducing the risk of urinary blockages and preventing life-threatening situations.

In short, Purina ONE high protein dry cat food has been a lifesaver for my cats. Thus, I highly recommend it to cat owners who want to prioritize their cats’ urinary health and provide them with a delicious and nutritious diet.

#2. Hill’s Science Diet Dry Cat Food – Best For Urinary Health Support

Editor’s Ratings:

Brand: Hill’s Science Diet | Form: Dry Food | Flavors: Chicken | Life Stage: Adult

What We Liked:

– Support urinary health with a low magnesium content;
– High-quality ingredients with real chicken;
– Control hairball with vitamin E, omega 6s, and fibers;
– Have no chicken by-product.

What We Didn’t Like:

– Only chicken flavor.

Product Highlights

My journey with this Hill’s Science Diet cat food started when my tabby cat developed bladder stones. The prescribed super-expensive food and the surgical options were out of my budget. 

Unfortunately, my cat didn’t like the Purina ONE option above. Out of desperation, I decided to try Hill’s Science Diet. And it has been a lifesaver.

This cat food supports urinary health and has natural ingredients, which is a big plus for my cat. I have used it to feed my tabby cat for many years, and this food has become an essential part of his diet.

Recently, due to financial constraints, I had to stop buying it for a month, and immediately I noticed a negative impact on my tabby cat. 

He became lethargic. After that, I had to rebuy this cat food, and he was gluttonous again.

Besides, I appreciate that this cat food solves common problems like hairballs. Since discovering this benefit, I have tried various types. And they have also been well-received. So I also gave this food to the rest of the cats.

But because its flavor is so appealing, be aware of your cat’s weight. My Siamese gained a pound after a month. 

Then, I carefully divide out 1/4 cup morning and evening, along with a spoonful of wet food. After that, her weight stabilized again.

#3. Royal Canin Veterinary Diet Cat Food – Best For Specially

Editor’s Ratings:

Brand: Royal Canin | Form: Wet Food | Flavors: Chicken | Life Stage: Adult

What We Liked:

– Good flavor;
– Formulated for urinary health;
– High-quality ingredients;
– Improve bladder health with RSS methodology.

What We Didn’t Like:

– High price;
– eed a veterinarian prescription.

Product Highlights

I used Royal Canin Veterinary Diet Cat Food for my picky cat having struvite crystals in his bladder. 

This cat food has been a game changer in managing her urinary problems, and I am delighted to have found a prescription food that she enjoys eating.

Before switching to Royal Canin, I tried various prescription canned foods, but my cat refused. 

It was a relief when I discovered this particular brand and flavor, as it appealed to her taste buds and made the meal much more enjoyable. Her willingness to consume the food is a testament to its palatability.

This canned food comes in a large can, and I give my cat half a can in one meal. This diet works for my cat and matches the recommendations from my vet. 

Its larger box means fewer additional trips and ensures I always have the suitable supply of food my cat requires.

Yet, I understand that the cost of Royal Canin veterinary diet cat food may be a concern for some cat owners. It is a specialized prescription diet with a higher price tag.

Thus, I recommend consulting with your veterinarian to determine if this prescription diet is appropriate for any cat with urinary problems or specific dietary needs.

#4. Blue Buffalo High Protein Wet Cat Food – Best For Coats

Editor’s Ratings:

Brand: Blue Buffalo | Form: Wet Food | Flavors: Chicken | Life Stage: Adult

What We Liked:

– Good flavor with a high percentage of meat;
– Make fur softer and shinier due to high-fat level;
– High-protein content;
– Various flavors.

What We Didn’t Like:

– The can is fragile.

Product Highlights

Like the other choices on this list, Blue Buffalo cat food has many benefits in supporting the urinary tract health of my cats.

But the notable benefit for me is its impact on my cats’ coats. Their coat has become noticeably softer and shinier since incorporating this food into their diet. 

I have observed similar results with other flavors as well. It is reassuring to see that food not only delights my cats but also contributes to the overall health of their coat.

Besides, I can easily open the box without a can opener. It’s convenient to have user-friendly packaging that doesn’t require additional tools.

Also, I find this food an option for older cats. I have an older cat who always dislikes wet food due to sensitive teeth. 

Unfortunately, his teeth have become too soft to chew food properly, and he often vomits after eating. 

When I took Blue Buffalo, however, his enthusiasm for mealtime returned. He would eagerly scream for it whenever I walked into the house, and he found it delicious.

I have the beef flavor now, but I’m trying the salmon or chicken options next. Having different flavors will add excitement to their meal and keep them engaged.

However, its can is very fragile. When I accidentally dropped it from the kitchen table, it cracked and could not be preserved for long. So you must be careful in storing these foods.

#5. Dave’s Pet Food Urinary Tract Cat Food – Best For Kidney Disease

Editor’s Ratings:

Brand: Dave’s Pet Food | Form: Wet Food | Flavors: Low Magnesium (Urinary Tract) | Life Stage: All Life Stages

What We Liked:

– Good for kidney disease;
– Support urinary tract health with a low magnesium content;
– Low phosphorus content;
– Fast delivery.

What We Didn’t Like:

– Slightly dry texture.

Product Highlights

I have been using Dave’s Pet Food urinary tract cat food for my cats; it has been effective for their kidney disease. Although I see many low reviews for this product, it has been a lifesaver for me and my feline friends.

This cat food comes in a slightly dry pate, but since cats with kidney disease require more water, I just added 1/4 cup water to half a can and pureed it. 

This recipe creates a moist texture that my cats love. I have never had any problems feeding them this food, and it keeps me and my fluffy friends stress-free during mealtime.

Sometimes, I even use a portion of food and cut it into small pieces for a little variety. Surprisingly, my cats also eat it in that form. This flexibility in serving style adds interest to their meal and keeps them interested.

Besides, I am impressed with its low phosphorus content. This trait is vital for cats with kidney and urinary problems, as too much phosphorus can worsen their condition.

Also, I appreciate the quick delivery of the food. It ensures I always have fresh food for my cats without delay or inconvenience.

What To Consider When Buying Low Magnesium Cat Food?

What To Consider When Buying Low Magnesium Cat Food

Here are a few tips that I came up with after searching for the best cat foods for my cats!

Ingredient Quality

First, consider the quality of ingredients as follow:

  • Read the ingredient list: Find high-quality protein sources as the primary ingredients. These can include named meats or meat meals, such as chicken, turkey, or fish. Avoid foods with generic terms like “meat by-products” or “animal digest.”
  • Avoid fillers and artificial additives: Choose cat foods free from fillers like corn, wheat, and soy. These ingredients offer little nutritional value and may contribute to allergies or digestive issues. Similarly, I recommend avoiding artificial colors, flavors, and preservatives.

Check for named fats: Look for healthy sources of fat, such as chicken fat or salmon oil, which provide essential fatty acids for your cat’s coat and overall health.

Balanced Nutrition

Next, consider balanced nutrition to ensure your cat’s health and well-being. I recommend looking for options with all the essential nutrients like protein, carbohydrates, fats, vitamins, and minerals.

Veterinary Guidance

Consulting with a veterinarian is vital in determining if low-magnesium cat food is for your cat. A veterinarian can assess your cat’s medical history, conduct relevant tests, and provide personalized dietary recommendations. 

Also, they can consider factors such as your cat’s current health status, any urinary issues, and the overall nutrient balance required for optimal feline health.
