Low magnesium cat food is one of the most prevalent concerns for pet parents. To help understand the issue and know what foods to feed your pet, read our in-depth article here.

It will explain what it is, how it can lead to problems in pets, and provide tips on how you can prevent issues from happening in your cat’s life.

Low magnesium can be deadly to cats. It limits the flow of oxygen in the blood stream and ultimately causes them to die. Pets supplemented with magnesium can live considerably longer than pets that are not.

This article will explain low magnesium and how you can help your cat by feeding them good quality low magnesium cat food.

What Is Low Magnesium?

In simple terms, it is a deficiency of magnesium in the body. Low magnesium will cause symptoms such as excessive panting, seizures, vomiting, and lethargy.

What Causes Low Magnesium?

Several factors can lead to low magnesium in cats, such as genetics, food quality, and environment.

A low concentration of magnesium in the diet or a change in diet can cause a deficiency in your cat.

Your pet can also have a low magnesium concentration if they eat too many processed foods loaded with salt and sugar.

Help prevent low magnesium in your pet by switching to a fresh, raw diet rich in fats and proteins.

Illnesses can also cause low magnesium, which includes diabetes, kidney disease, heart disease, and cancer.

Symptoms of low magnesium include lethargy, lack of appetite, and vomiting.

Your cat will also have tremors and seizures if they are not receiving enough of the mineral.

Additional symptoms that may occur are heart rhythm abnormalities, abnormal cardiac contractions, muscle cramps, and other conditions.

What Is A Good Magnesium Level In Cat Food?

A good level of magnesium for cat food is around 25 mg per 100 grams, as stated by PetFinder.

This amount should be spread over several servings daily, as your pet needs to get a good magnesium balance in their diet.

The right balance can help improve their state of mind and overall health.

What Are Some Foods High In Magnesium?

Some food sources high in this essential mineral include egg shells, spinach, pumpkin seeds, sesame seeds, yogurt, and bananas.

Milk and tofu are also good sources of this mineral.

How Can I Get My Cat To Eat Low-Magnesium Cat Food?

Introducing a new diet to your cat can be difficult. They are used to eating the same food for years on end, so trying out something new can make them upset.

If you decide on buying them low-magnesium cat food, there are several ways of making it more appealing to your pet’s taste buds.

This includes mixing the new food with their old cat food, so they get used to it gradually.

You can mix small amounts of the new diet with their regular pet food and increase the amount you add over time.

This helps your cat’s stomach get used to this different taste, which makes them more likely to want it in future meals.

Dry Or Canned Low-Magnesium Cat Food Will Help?

There are many options when feeding your cat low-magnesium foods, including dry or canned foods. Canned food is easier for you to prepare, but the risk of your cat choking can be higher.

You should also ensure that the canned food you plan to buy has been produced with low-magnesium ingredients.

You can choose between dry and kibble-type foods if you buy dry options. You can then decide on what type of food your cat prefers. Some cats will only eat kibble, while others will eat both types of diet in different meals.

How Much Magnesium Should Cat Food Have?

The exact amount of magnesium in cat food depends on the content of the diet, so manufacturers do not provide this information.

Canned food contains less magnesium than dry food but has trace amounts. The amount of magnesium in each type of food will depend on the content of your cat’s diet.

Low-magnesium cat foods generally contain less than 0.1% magnesium for your kitty’s healthy urinary tract and kidney function. It is important to monitor your cat’s urinary health and check the label carefully when buying its food.

In addition, you should also check their weight regularly, as cats will gain weight if their diet has high levels of magnesium. In general, canned food contains less magnesium than dry low-magnesium cat food.

Low Magnesium Wet Cat Food

Low magnesium wet cat food can benefit cats with certain medical conditions such as urinary tract disease, kidney disease, and bladder stones.

These conditions can be aggravated by high levels of magnesium in the cat’s diet, so a low magnesium diet can help manage these issues.

When choosing a low-magnesium wet cat food, it’s important to read the label carefully and look for a food that meets your cat’s nutritional requirements.

It’s also recommended to consult with a veterinarian before making any dietary changes for your cat.

Some popular low magnesium wet cat food brands include Hill’s Prescription Diet, Royal Canin Veterinary Diet, and Purina Pro Plan Veterinary Diets.

These brands are formulated to be nutritionally complete and balanced while also being low in magnesium.

Ultimately, the best food for your cat will depend on its needs and medical history, so it’s important to work closely with your veterinarian to determine the most appropriate diet for your feline friend.

What Is Considered Low Magnesium In Cat Food?

The ideal magnesium level in cat food will depend on the cat’s needs and health condition. The Association of American Feed Control Officials (AAFCO) generally recommends a minimum of 0.04% magnesium on a dry matter basis for adult cat maintenance.

However, a low magnesium diet may be recommended for cats with certain medical conditions such as urinary tract disease, kidney disease, and bladder stones.

The specific magnesium levels in a low-magnesium cat food will vary depending on the brand and formulation. Still, generally, a low magnesium cat food will have a magnesium content of less than 0.1% on a dry matter basis.

It is important to note that while a low magnesium diet can benefit some cats with medical conditions, it should only be implemented under the guidance of a veterinarian.

What Is Considered Low Ash or Low Magnesium?

The amount of ash and magnesium in food is also not mandatory, so it will also vary based on the type of food you buy.

Ash is a protein component, and this content can be derived from animal, fish, or vegetable products. For example, a diet with less than 1% magnesium is considered a low-ash diet.

Other fish with low magnesium levels include salmon, trout, sardines, and tuna. Cats who suffer from urinary problems may be prone to kidney problems over time. A cat with a urinary tract infection may have to be on a low-magnesium diet for life.

Dietary changes will help reduce urinary issues’ symptoms and prevent your cat from re-acquiring urinary problems.

Low Magnesium Cat Food Reviews

Most cats prefer to eat canned food. Those who only eat dry food will often face more dental issues.

Dry cat food is also cheaper than canned food, making it a popular choice among cat owners. However, dry cat food has higher levels of ash and magnesium than canned foods.

Therefore, you should choose foods with low ash content and low magnesium options to follow a feline diet created by your veterinarian or specialist in feline medicine.


While you may need to limit your cat’s dry food intake, feeding them a low-magnesium diet is a good idea.

Low-magnesium foods are easily found on the market, but you should always check their labels carefully before feeding them to your pet. A healthy urinary tract and kidneys ensure your cat feels great!
