The Natural Diet of Cats

Cats are one of the most successful carnivores of the world. The wild version of your friendly feline pets, are true survivors, adapted as stealth hunters of small prey- hunting and consuming rodents, lizards, birds, insects, and frogs.

Everything cats require for a balance nutritious diet comes from the meat, bone, skin, and organs of these creatures.

 

The Necessity for Protein in a Cat’s Diet

One of the main health benefits of grain free cat food is a cat’s reliance on protein. They require plenty of it, and the best digestible form of protein cats can get is from meat. In the wild, cats do not consume large amounts of carbohydrates. They have evolved to only require small amounts, which they can also get from meat.

 

An Overload of Carbohydrates is Unhealthy for Cats

The trouble with grain and other starchy plant ingredients in many of the commercial cat foods, is that they are overloaded with an excess of carbohydrates. Carbohydrates are difficult for a true carnivore to digest. This is because cats do not produce the salivary amylase enzyme needed to break down food containing high levels of starch.

A high consumption of carbohydrates is harmful to a cat’s health and should be avoided where possible.

Commercial cat foods commonly include grained fillers such as wheat, barley, rice, corn, and/or soy. This is particularly more evident with dry cat foods than wet.

3 Benefits of Grain Free Cat Food

Shiny Lustrous Looking Coat

Cats with sensitive skin and intolerances will greatly benefit from a grain free cat food, because foods with grains have been linked with allergies that cause skin problems. Itchy flaky skin will result in anxiety and scratching. A cat with allergies will readily have a fur coat that loses its luster.

Settled and Easier Digestion

A digestive system evolved to digest meat, will have challenges when processing excessive grains. Unsettled digestion can lead to diarrhea and inefficient uptake of nutrients. An unsatiated cat will want to eat more, as its body will be craving nutrients.

Trim Healthy Weight

Cats eating too much carbohydrate are prone to putting on weight, especially if they are inactive cats. Obese cats can often become diabetic cats. A grain free food will be a step in the right direction for healthy weight management of cats.

 

What Cat Owners Should Know About the Best Grain-Free Cat Foods

Buying a nutritious grain free cat food that is healthy, balanced and providing the full spectrum of nutrients has challenges. Not all grain-free cat food meets the needs of cats.

Some manufacturers remove the natural carbohydrate elements from their food as well as replicate nutrients usually gained from meat, such as the essential amino acid- Taurine (* refer to note at the bottom of this article). They do this by adding supplements. However, replacing nutrients with supplements does not always benefit cats and can lead to similar problems with digestion and allergies.

A decent grain free diet needs to provide cats with all the nutrition crucial for healthy bodily function and growth.

The food needs a broad range of vitamins and minerals; fats; some carbohydrates; and most importantly high levels of meat proteins. There should be no carb replacements added.

 

What to Look for in a Quality Grain Free Cat Food

Meat Protein

The best grain free cat food will have a high level of protein from a quality meat. Look for food with real meat as its number one ingredient, as opposed to meat by-products.

Cats require at least two grams of protein per pound of healthy body weight in the number of calories they consume each day. Seek cat foods with at least 25% protein.

Natural

Seek products with natural ingredients, rather than synthetic- preferably organic, chemical free, no artificial flavor/color/preservatives and non GMO.

Starch

If starchy plant-based foods are included, ensure that they are listed lower down on the ingredients list, and preferably in the form of vegetables, rather than grains.
