An perfect food regimen for carnivores consists primarily of animal elements (meat, poultry, eggs, and fish) with minimal carbohydrates. Within the wild, cats get all the things they want from the tissues, organs, bones, and abdomen contents of their prey.

Should you had been to burn the entire carcass of a mouse, for instance, you’d be left with ash. The identical form of ash is left behind when industrial cat meals merchandise are burned.

A product that options hen meat may be decrease in ash than one which options hen meal. As a result of hen meal is typically derived from entire hen carcasses, it might comprise pores and skin and mineral-rich bone in addition to muscle meat. Animal by-products and by-product meals are additionally prone to improve the ash content material of a product as a result of they might embody necks, toes, and different bones. Chicken and fish are inclined to have decrease ash content material than darkish meats like lamb and beef.

And don’t neglect to contemplate added nutrient dietary supplements. Artificial minerals like calcium carbonate, potassium iodide, or sodium selenite contribute to the product’s ash content material.

Some proof suggests chelated minerals—mineral molecules sure to protein molecules—are extra simply absorbed by the physique. The extra absorbable one thing is, the much less of it’s required.

Within the Seventies and 80s, researchers found a hyperlink between excessive mineral content material in cat meals and urinary crystals. They concluded that high-ash cat meals elevated the chance for urinary tract issues like struvite crystals. However we’ve since found it’s extra difficult than that.

When the cat’s urine pH turns into very alkaline, struvite crystals are fashioned from magnesium, phosphorus, and ammonium. Quite a few well being circumstances can have an effect on urinary pH, as can the protein content material of a cat’s food regimen.

Many pet meals producers decline to incorporate ash within the Assured Evaluation for his or her merchandise and the reasoning is straightforward: customers are prone to misread it.
