CHAMPAIGN, Ill. (WCIA) — After Betty White passed away on Dec. 31, social media users came up with a new challenge to honor the legendary actress on what would’ve been her 100th birthday.

In addition to being an entertainment icon, White was a longtime animal lover and advocate for animal rights. To honor White and her contributions to animal welfare, social media users created the Betty White Challenge.

On Jan. 17 – the day White would’ve turned 100 years old – people are encouraged to donate $5 to an animal shelters or animal rescue groups in their area of residence.

People can participate in the Betty White Challenge by donating to the Champaign County Humane Society. The CCHS will accept donations online, by phone (217-344-7297), by mail and at their shelter in Urbana, located at 1911 East Main Street. Donations made using credit cards, checks and cash will all be accepted.
