There's an ASPCA ad right now that makes me just about bawl every time I see it. It plays that Sarah McLachlan song, "Angel," which has been used for just about every emotional event from 9/11 to various murder cases, and it breaks your heart, especially when set against the backdrop of those poor sad animals.
I just want to open the cage doors and take them all in.
The ASPCA has a whole channel on YouTube, with videos and a donation button. God bless them and their work. I need to make a donation soon.
