Thank you all for the kind words.
Here is the most recent pic of him, with my mom:
My sleepy man:
On the cat tree he loved so much:
Toonces came to us as a stray, on the 4th of July. We had gone to fireworks and he was sitting on the front porch when we returned. My stepsister named him after Toonces the Driving Cat on Saturday Night Live. He was mine from day one. For him, the sun rose and set with me. He would enjoy others, but he always left them for me when I came home. His fur dried my tears many a time as I was growing up, and his purrs lulled me to sleep. There will never be another cat like him. Never.
