Meet World's Richest Cat Italy's Tomasso inherits owner's $13.4 million estate, sort of By Mark Russell, Newser Staff Posted Dec 10, 2011 7:16 AM CST 9 comments Comments File photo: This cat looks like Tommaso but is nowhere near as rich. (Shutterstock) (Newser) – Now that's some serious scratch—Tommaso, a 4-year-old former stray, is now the world's richest cat, the inheritor of $13.4 million worth of properties around Italy, reports the Guardian. Tommaso's rich owner, a 94-year-old childless widow, died last month, leaving her entire estate to her cat. However animals cannot inherit property directly in Italy, so the widow named a cat-loving nurse she met in a park as Tommaso's trustee. "I had no idea the signora had such wealth," said the nurse, identified only as Stefania. Tommaso may be the world's richest cat, but he still has a long way to go to before the can compare to the world's richest dog—Gunther IV, a German Shepherd from Germany, is said to be worth $372 million.
