"They don't know they have more money than most people," live-in caretaker Roy Grady said of Buckshot, Katie and Obu-Jet, who reside in their late owner's home in Hagerstown.

Ken Kemper died of cancer last year, leaving $400,000 in investments and a home worth about $400,000 to his dogs, the Hagerstown Herald-Mail reported Sunday.

Katie and Obu-Jet, both lab mixes, and Buckshot, a beagle, were strays when Kemper adopted them. Grady said he does his best to spoil them, including treating them to a spaghetti dinner with meatballs and garlic bread each Friday night.

Kemper worked for the Voice of America, a broadcasting service funded by the U.S. government, and was known for returning home with stray dogs from his travels around the world, Grady said, noting the remainder of Kemper's estate will be given to an animal charity when the three dogs, each about 10 years old, die, the Herald-Mail reported.
