“Understandably distraught when his beloved cat Bob died in 1862, the writer was eager to keep a visual memory on his desk. One of Bob’s paws was promptly stuffed and adhered to an ivory blade, which was engraved “C.D. In Memory of Bob 1862.”
There is a picture of said letter opener via the link. I’m still not quite sure what I think about it, but it seems entirely like a Chaz thing to do. Didn’t he also have his pet raven stuffed as well?
Was just about to post this article! The Raven Grip was also stuffed, and is now on display at the Free Library of Philadelphia’s Rare Book Department. It’s pretty creepy to see in person (they also have plenty of other Dickens-related holdings).
