Well, I'm already getting the unhealthy wet food cuz he won't eat the healthy kind, but after switching to Innova EVO cured Ringo's diabetes, I figure it's a preventative health maintenence thing that will lead to less scary vet bills.

I'm not grinding it that much. Just like we would for walnuts/pecans in snow balls. But straight PB with no additives is fine for cholesterol (and what I use for baking) it's when they add the hydrogenation to make it creamy that it gets bad.
