Francesco Morosini (1618-1694) , the Doge of Venice who battled the Turks and laid siege to Athens, was said to have two loves. One was the glory of his country (Venice was its own state at this time). The other was his cat, whom he took on all his military campaigns whether by sea or on land. After her death, Morosini lovingly preserved and kept her skeleton.
A little bit on Morosini here. I couldn't find anything else about the cat, but gleaned this from Jan Morris' A Venetian Bestiary (London: Thames and Hudson, 1982) p. 70.
