I only splashed a small amount on top of his head so I doubt he swallowed much if he did swallow any at all. While it may have been downright unpleasant for him, it wasn't exactly pleasant for me having him chew away on my thumb. Besides, alcohol was the only tactic that I'd heard of (besides water) and I didn't see any other way of getting him off. While the grappa didn't make him sick, I will try something else. Maybe something with a little less alcohol in it. Hand sanitizer? Nah, too valuable these days.
