Vitamin B12 is essential for the immune system to function properly. In addition, when the kidneys are failing the body often becomes depleted of the b vitamins.
However, even though it becomes essential for cats to have B vitamins that doesn’t necessarily mean it has to be in the form of a supplement.
It may be surprising to some of you to hear that some foods contain very high levels of B vitamis and that when the raw diet is provided properly it contains all the bs your kitty will need!
Synthetic aren’t always best for our kitties because our cats come from nature and synthetic vitamins are formulated in laboratories! In my opinion their vitamins, and food should come from nature as well!
In just 4oz of beef liver you can find about 70 mcg of B12. Duck eggs contain 6mcg and 25 mcg can be found in 3oz of beef kidney.
Cats only require about 20-50mcg per day which can easily be attained through diet!
