Caveat has good stuff, including a link to PETA's 2007 kill rate, which seems higher than last year's.
KC Dog Blog also has good stuff, including some info on the media. Thanks for the plug for Banned Aid.
And Pet Connection has good articles about the tragic death of Eight Belles in the Kentucky Derby.
Go forth and read. And leave a comment so the authors know you were there.
