Yes! Excellent, he's driven Mark away from his clothes.

Only, wait, that's not what Ravi had been intending to do. He needs help to make sure he doesn't stay a rodenty ferret forever, which means that Mark wandering away is the last thing he wants to happen, which means he needs to figure out what to do. Scrambling, he looks to the dewy, wet ground and works to start carving in words in the dust as best as he can, dragging his little paws in and stumbling a little because it's not like he ever got lessons on how to do this.

When he's managed to scribble 'RAVI' in childlike writing, he scampers to Mark's ankle to nip and gnaw at the pants there.
