I have found that if I forget to close the lid of my barbeque after an evening cook-out, one of my cats, Buchi, can be found licking the grate the next day when he is let out! Probably not very good for him...though what a tasty treat. I promise it doesn't happen often...smile. Maybe your's is hitting the neighborhood backyard grills...especially now that summer has arrived and people are grilling more often.
