BREAKING: Thanks to YOUR calls and emails, the Beagle Bill has finally passed the Pennsylvania House—unanimously! 🥳 The bill would prohibit the sale of animal-tested cosmetics & give dogs & cats an opportunity to be adopted into loving homes after the experiments are over! 🐾

From fragrances to painkillers to clothing fabric dyes, every new chemical has at one time been tested on animals. We're working with companies & governments to replace cruel & obsolete chemical toxicity tests with animal-free methods that better protect human & enviro safety.

Last year, JD Jiggles & Socorro finally met face to face —and instantly hit it off with an adorable play session! 💕 After decades in a laboratory, these two have been able to experience so many “firsts” at @ChimpHaven sanctuary—including meeting chimps of the opposite sex! 🥰

100y ago, we traveled by steam train & communicated by telegram. Today, we have spacecraft exploring Mars & smartphones. Yet when it comes to testing drugs & chemicals, animals are still subjected to methods developed a century ago. It's time to leave animal testing in the past!

‼️ Arthritis medication Vioxx, weight-loss drug Fenfluramine, & allergy drug Seldane all passed animal tests, yet caused heart attacks and strokes, in humans. These incidents show why we need to prioritize animal-free, human-relevant methods. Learn more: humaneworld.org/en/news/limi…

#WorldMentalHealthDay 🧠 Over 90% of drugs that pass animal tests fail in clinical trials. One reason is animals brains function differently than ours. This is why we support non-animals methods like brain organoids, which help us better understand & treat mental health issues.

Donny used to live in an @EPA lab where he was used in harmful chemical tests. But in June 2025, all that changed when he was adopted by Marci Smeltz, a scientist at the lab who develops non-animal alternatives. 🐰❤️ Learn more about Donny & Marci ➡️ humaneworld.org/en/all-anima…

If animals could speak, what would they say about how we treat them in the name of science?

DYK that quail are used in ecotoxicity tests? 😲 Some tests require force-feeding chemicals to the birds to measure abnormal behavior, egg quality & to determine the dose which causes death. Animal-free methods can provide more accurate safety data without animal suffering.

The 2026 #WorldAnimalDay theme is “See the world through their eyes.” Imagine being in a cage when a hand reaches in, grabs you & causes you pain. 😢 That’s why we’re working until every cage is empty & advocating for non-animal methods that benefit people, the planet & animals.
