Twitter for the Critters Celebrity Challenge Underway

Combining fandom with philanthropy, admirers of animal-loving A-listers can show their love for both stars and Spots by making a donation to the Twitter for the Critters Celebrity Challenge.

Billy Ray Cyrus, Miley Cyrus, Twilight‘s Peter Facinelli, Kelly Osbourne and Eric Stonestreet from the ABC series Modern Family are currently requesting donations of $5 or more for The Onyx and Breezy Foundation, which has helped pets in peril since 2004.

The challenge runs through February 19, 2012, with 100 percent of all donations received benefiting animals in need.

To make a donation:

As an added bonus, if at least $25,000 is raised by the end of the drive through the combined efforts of the stars, one donor from the team which raised the most funds will receive an “Animals Cannot Speak for Themselves” poster. A prized possession for any autograph hound, the item has been signed by the following 89 notables:
