This is the song at soundtracks those ubiquitous ASPCA (American Society for the Prevention of Cruelty to Animals) commercials
that have been running since 2007. The spots are a serious downer, showing frightened and abused animals in slow motion interspersed with messages like "they suffer alone and terrified." They often come on late at night when TV stations donate unsold advertising time to charity, so you could be enjoying an old movie in the wee hours when suddenly you're looking at a caged kitty that seems to be crying for help. Many change the channel.
A bane of insomniacs, the spots nonetheless proved incredibly effective, generating over $30 million dollars in donations. They also inextricably linked McLachlan, who appears in some of the spots, with abused dogs and cats.
When she made the commercial, she didn't think it would be a very big deal; she simply donated a few hours of her time and use of her song. And while she supports the cause, she isn't as passionate about it as many believe. "I love animals as much as the next person, but if I really wanted to attach myself to something, it would be kids and education," she told the Charlotte Observer
in 2015. She also admits that she can't watch the spots.
