Wonder if Big Pharma gave funding to write this article. Sorry, just don't trust media much anymore. Not saying the test isn't true. But I guess all cat owners are now in the target of big government. I say eat some cloves and black walnut hull every once in a while and don't worry about the parasites unless problems start to occur. Native Americans used black walnut hull to control parasites in the gut; not sure if they'd be useful in other parts of the body.
