What Is Considered When Choice Low Ash Cat Food

Choosing low ash cat food comes with several factors to consider. Notably, the moisture content in the food is essential as it aids hydration and digestion. For instance, Purina ONE with Real Chicken is a great choice due to its high moisture content.

Besides that, protein sources of food matter too. As cats are carnivores by nature, opt for foods with genuine meat such as chicken or rabbit rather than unspecified meat products like ‘meat meal’.

Nature’s Logic Feline Rabbit Feast stands out in this regard. Food brands also make a difference. Some brands like Smalls and Nature’s Logic offer low ash options specifically tailored for felines with sensitive stomachs; hence it would be wise to go for these trusted brands when possible.

Additionally, mineral balance must be maintained since excessive magnesium, typically found in high ash cat food can cause digestive issues and urinary problems like crystals formation in urine.

Frequently Asked Questions

Why Is There Ash in Cat Food?

Ash in cat food signifies the inorganic mineral content that remains once the organic portion of the food is burned off. It’s not actual “ash”, but refers to essential minerals such as calcium, phosphorus, zinc, magnesium, and iron in your feline’s meal.

These elements are crucial for numerous vital functions like bone development and enzyme activity. Therefore, opting for low ash cat food becomes an important consideration for overall cat health.

How Can I Tell How Much Ash Is In The Food?

To determine the ash content in cat food, you can find this information on the product’s label or by contacting the manufacturer. Some cat food brands may not disclose the ash levels on their labels, but it is always worth checking with them directly.

Additionally, foods with less than 5% ash are considered low ash, while those with more than 8% ash are considered high ash. Maintaining a low ash level in cat food is crucial for maintaining acidic urine and preventing cat urinary tract issues.

Do I Need A Prescription?

Prescription cat food is recommended if your cat has a medical condition such as kidney or urinary tract problems. However, low ash cat food does not necessarily require a prescription.

Does Wet Cat Food Have Ash?

Wet cat food generally has lower ash content compared to dry kibble. This is because wet cat food contains a higher moisture content, which helps dilute and flush out minerals.

Is Ash a Cat Food Filler?

Ash is not a filler in cat food but an essential component that provides necessary minerals. The term “crude ash” on a cat food label refers to the amount of minerals like calcium, phosphorus, and other nutrients.


As you’ll have seen, almost all the foods in my five choices are specifically low in magnesium rather than in their ash content as a whole.

There are also many other factors besides ash content, such as protein levels, regulation of urinary pH, and hydration that constitute good urinary tract care for cats.

After researching the top options available in 2023, I recommend Purina Fancy Feast Grilled for its delicious seafood flavor and Iams ProActive Health Urinary Tract for its specially formulated ingredients.
