While Hollywood has embraced the ALS Ice Bucket Challenge, Pamela Anderson is staying dry.

The actress hit Facebook Wednesday to criticize the super popular fund-raising campaign over the organization's research practices. She wrote, "Sorry, I can't bring myself to do your Ice bucket challenge. I enjoy a good dare. It's always good to bring awareness -- in fun, creative ways, I don't want to take away from that. I thought instead, I'd challenge ALS to stop animal testing." 

The longtime animal rights activist went to to describe the "cruel" experiments animals had to endure in ALS's attempt to find a cure. "Recent experiments funded by the ALS Association, mice had holes drilled into their skulls, were inflicted with crippling illnesses, and were forced to run on an inclined treadmill until they collapsed from exhaustion. Monkeys had chemicals injected into their brains and backs and were later killed and dissected."  Then she urged people to "find and support charities that never harm animals."

So far, more than $41 million has been raised for the ALS Association.
