SOLVED. Cat story for older children, begins with C! [s]

[Saran]

This book (or was there more than one) is on the tip of my brain but I can't Google it as I can't remember what the cat was called. He had a name beginning with C and I think he was a royal cat. My sister had these books growing up and I borrowed them, without telling my friends! But I enjoyed them!

C-something the cat? C-something the King?
Agghhhhh, memory!
