She could chew on this squirrel for hours, and she usually does it right at the most inopportune times, like in the middle of a really important phone call. Wouldn't be so bad if it didn't squeak so loud that it sounds like it can feel that it's being chewed to death. But I don't have the heart to take it away. Although I will occasionally put it on a shelf high enough that she can't reach it. For hours. Blissfully silent hours.
