The vet's office sent their condolence card, complete with pawprints, and signatures and wishes from everyone in the office. This was beautiful, and the pawprints just about did me in.
Not my usual style, but so lovingly done, who could resist.
Update on Duncan: he seems to be seizing the day and attaching himself to me at all times, being an only cat. Eating just fine, too. So perhaps he's handling it okay.
