Claire Nelson of Reading, Pennsylvania, adopted Rusty as an adult cat from the Humane Society. Two years later, in June of 2011, Nelson wanted to lay down because she wasn’t feeling well, but Rusty kept bothering her, which was out of character for him. The 66-year-old former nurse took inventory and decided to visit her doctor’s office, but Nelson began feeling much worse at the bus stop and called 911. Doctors at the hospital found that she had suffered a heart attack! Surgery followed and Nelson had two stents implanted. When she returned home, Rusty was back to his normal self, but would not leave her side. Nelson credits him with saving her life.
