Ingredients Analysis

The first ingredient is beef heart.  Although it doesn’t sound very appetizing to us humans, heart tissue is pure muscle — all meat.  It’s naturally rich in quality protein, minerals and complex B vitamins, too.

The second ingredient is beef liver.  This is an organ meat sourced from a named animal and thus considered a beneficial component.

The third ingredient is green lipped musselsMussels are clam-like animals notably rich in glucosamine and omega-3 fatty acids, nutrients proven to support long-term joint health.

The fourth ingredient is cheddar cheeseA protein-rich, lactose-free dairy product high in calcium and other healthy nutrients.

The fifth, sixth and seventh ingredients are monterey jack cheese, swiss cheese and romano cheese.  All are protein-rich, lactose-free dairy products high in calcium and other healthy nutrients.

The eighth ingredient is shiitake mushroom.  Shiitake mushrooms are an edible mushroom which are often categorized as an medicinal mushroom due to reported benefits to increasing lifespan and liver health, alongside many other areas.  

Studies are ongoing, however, Shiitake mushrooms are a source of dietary and prebiotic fibers and plant based compounds, such as polyphenols, polyamides and glutathione.

From here the list goes on to include a number of other items. But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of the product.

There are two notable exceptions in this recipe.

The inclusion of dried fermentation products in this recipe. Fermentation products are typically added as probiotics to aid with digestion.

However, this recipe contains dried yeast which can be a controversial item.  Dried yeast contains about 45% protein and is rich in other healthy nutrients. 

Fans believe yeast repels fleas and supports the immune system.

Critics argue yeast ingredients can be linked to allergies.  This may be true, but (like all allergies) only if your particular cat is allergic to the yeast itself. 

In any case, unless your cat is specifically allergic to it, we feel yeast should be considered an addition.
