Not saying this is incorrect but that's hard to believe as raw diets are usually 80-95% raw meat and taurine comes from animal protein and not plant proteins. Cooking the meats is what destroys taurine and why it's added back into kibble. If raw diets are linked to DCM it shouldn't be from the lack of available taurine but maybe an unbalanced diet that was concocted (this is why I don't recommend getting a raw recipe from the internet).Raw diets have also been found to be a suspect in DCM.
How the whole taurine thing was originally figured out was back in 1987, I believe, they found that cats were getting cataracts early and heart issues. They found that these were indoor cats and cats that were outdoors frequently weren't having this issue at all (they were catching live animals and eating them). So they starting pumping taurine into the diets and no more incidences of cataracts or heart issues. Cats require a much higher level of taurine then a dog does, but they both need it. But a raw diet should not contribute to the low taurine diet related DCM issue.
Maybe prep people are buying the lowest quality of meat possible but even then taurine levels shouldn't be effected. The phosphorus and ash level can change based on quality but not the amino acid taurine that I'm aware of. Not that extent.
