I was feeling like a wacky treat was in order, so just this one time I gave my Oscar a piece of dog food. I could hear him crunching it up! It was sooo loud! Worth a try if you're okay with a one-time contamination. Heck, some people feed their O's cat and dog food regularly. It causes fatty liver disease in the long run, but once in a rare while really ought to be fine, wouldn't you think? It sure is neat...
