truckmountgirl Yes, an asphalt re-grinder ought to do the trick. That is some serious grinding. I wonder if pulverizing with a heavy mallet, about like splitting wood might do the trick for small batches. I like your idea about making your own dog & cat food. I had an aunt that did that, long before it was cool. She sadly to say died about two years ago at nearly 100. She was the last to go on my Mom’s side of the family.
