Profits from the sale of John Petrucci's strings go to Best Friends: Nearly 30 years ago, Best Friends, an animal welfare society, helped pioneer the no-kill movement. At that time, more than 17 million homeless pets were dying each year in our nation's shelters. By implementing spay/neuter and trap/neuter/return (TNR) programs to reduce the number of animals entering shelters, and increasing the number of people who adopt pets, we've reduced that number to around four million deaths annually. See more at http://bestfriends.org
