I use omega Plus from Food Just For Dogs, it’s human grade and my cat specialist checked it out said it’s top of the line, for 10 lb cat I use 1/8 tsp daily. They eat it with their treat or in their food. Very high quality.Thanks guys. I am going to add some to my kitty's food because he has been having skin and health problems lately. I hope it will help to boost his immune system and clear up his skin. I just wanted to be sure that it's okay to give it every day? I don't see it as an ingredient in the regular food he's eating.
