I put 1/8 tsp. Turmeric in the ragdoll's food because he has a cyst in his ear. He refused to eat it all day and in the evening he threw up a very small amount of the food. Will have to try putting it in his poor ear. He now eats a raw diet, also. He is 15 years old and been on dry food most of his life, and grain free and wet food the past few years.
