As I've thought more about Cyrano over the last day or so, I realize that he was ready to go and had been letting us know in his own way. Over the last few weeks, we had been seeing less & less of him as he stayed by himself, usually in a nice warm spot in the closet.
J mentioned on Monday morning (just after he had died) that she had dreamed about him, & that he had seemed like his old self. I find that comforting, & I hope that he didn't feel that we were making him stay longer than he wanted by giving him special diets, fluids, etc. to keep his strength up.
The tag from his collar is on my key chain next to his best friend's Solomon's, & though I miss them both, I'm happy to know that they're able to cuddle & give each other baths again like they used to.
I'll have to find a picture of them together to post.
