It looks like they are made from cow tails, so I imagine they are mostly cartilage. I don't know if they are stinky or not, although if they are smoked there is probably some odor. I happen to know Susie Merrick (one of the owners) through some volunteer work, and the Merrick plant is only 45 miles from where I live, so I've actually been there and seen how the test animals are treated (like pets). I wouldn't have any qualms about using their products. |
