Pamela Anderson made a public statement Thursday declining her Ice Bucket Challenge invite due to ALS‘ involvement with animal testing.

“Sorry—I can’t bring myself to do your Ice Bucket Challenge. I enjoy a good dare— It’s always good to bring awareness,” the “Baywatch” actress posted on her Facebook page. “I found that we may not be aligned — in our messages. So… I thought Instead / I’d challenge ALS to stop Animal testing.”

Anderson is a well-known animal rights activist, who has worked with PETA for many years.

The actress continued:

“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. What is the result of these experiments (other than a lot of suffering)? In the past decade, only about a dozen experimental ALS treatments have moved on to human trials after being shown to alleviate the disease in animals. All but one of these treatments failed in humans—and the one that “passed” offers only marginal benefits to humans who suffer from ALS. This massive failure rate is typical for animal experiments, because even though animals feel pain and suffer like we do, their bodies often react completely differently to drugs and diseases. According to the FDA, 92 out of every 100 drugs that pass animal trials fail during the human clinical trial phase.”

The actress urges ALS to use “sophisticated non-animal testing methods” and posted a picture of herself by a pool holding a sign that says “Stop animal testing.”

A rep for the ALS Association could not be immediately reached for comment.
