The reason it is confusing when it comes to raw diets and taurine is because ground meat has a lot less taurine than natural, non ground meat.
When you grind meat it loses a lot of its vitamins, including taurine. It also makes it more susceptible to bacteria. That's why it's recommended you give whole pieces of meat and bone rather than ground. Then you know you're giving your puss enough
