Just Got A Puppy And Kitten, Which Raw Ratio Is Best To Feed?

+Adding in a puppy or kitten to your life can be very exciting and full of wonder! But unless you know about their daily requirements and needs, homework will have to be started.

Popular B.A.R.F and P.M.R diets are not meant or recommended for pets under the age of 1 year, geriatric pets, or pets with debilitating health issues. B.A.R.F. (Biologically Approved Raw Food or Bones And Raw Food) and P.M.R (Prey Model Raw) are two very common models in raw food. These ratio diets can be dangerous if feeding long term as they are in no way nutritionally balanced, even with rotating meats. Ratio diets are best suited for adult dogs or cats who are being introduced to raw, and is intended not to be fed long term.

B.A.R.F. and P.M.R. is heavily flawed diets when it comes to nutrients. These diets depend on feeding only a certain percentage of meats, bones, offals, and other ingredients depending on the B.A.R.F. ratio followed. P.M.R. is commonly spelled out as a 80:10:10 diet; as in 80% meat, 10% bone, and 10% offal, with a disclaimer of 10% of the offals never exceeding more than 5% in liver. B.A.R.F. has a similar skeleton to it, with a 70:10:10:6:2:2 ratio being thrown out (though variants of B.A.R.F. diets do exist) 70% meat, 10% bone 10% offal 6% veggies 2% fruits and 2% seeds.

Depending on a certain percentage to meet your pets daily needs is just as silly as it sounds, as different foods will have different nutritional values, even different cuts of the same animal used for protein will differ in nutrition. Many people with this “ratio mindset” will tell you that rotation of the proteins will ensure their pet is getting the nutrition they need over time. Sadly, this is not how the body works, and it will not hold on to extra vitamins or minerals from one day to make up for a day without those vitamins or minerals. Cats and dogs must have their nutritional requirements met in order to have a properly healthy and functioning body, that will not suffer from any sort of imbalance or deficiency.

If we look into, specifically, the 10% bone that is shared in both P.M.R. diets and B.A.R.F. diet, you will see that this is an issue for calcium intake. The NRC Nutrient Requirements of Cats and Dogs reports adult cats as needing a recommended allowance of .72 grams of calcium, while adult dogs need 1 gram of calcium. Puppies have a recommended allowance of 3.0 grams of calcium while kittens need 2.0 grams in comparison!

Puppies and Kittens cannot regulate vitamins and minerals efficiently, and can be harmed the most if feeding and depending on a ratio diet. So please do your homework, research nutritional values of each ingredient you plan giving your growing pet, or reach out to a Raw Pet Nutritionist, or FEROX, who is best suited to help ensure your new family member gets exactly what they need!

I’ve alwaYs fed ratio PMR 80:10:10 using 5% kidney and 5% liver, but your post makes sense. There are various minerals in each liver type whether it be calf liver, chicken, turkey, beef etc.
