Adopt pets and donate by January 17th, the day she would have turned 100. Fans are rallying to honor Betty White by supporting one of her biggest passions: animal welfare. The challenge is simple: donate $5 to any local or national animal shelter, rescue or agency in White's name leading up to or on her birthday January 17th.

Saddlebred Rescue Inc says let's see how many horses we can save from slaughter for the challenge. Current auction prices have been on average $900-$1200 per horse. Make your donation and the "Friends of Saddlebred Rescue" will match your donation!
