“Those animals are still there, and we’re doing everything we can to get them out.” — NAVS’ Robert Hollocher

After joining the March to Abolish Animal Testing (March for Animals), Robert returned home with new connections, renewed determination and the weight of leaving animals behind at Marshall BioResources.

In our recap, he shares the moments that stayed with him, from the solidarity along the route to the emotional leash vigil outside the facility.

Very busy. Very fierce. Very distracted by that toy.

This National Cat Day, we’re celebrating the curiosity, playfulness and personality that make every cat an individual.

Every cat deserves the freedom to play, explore and feel safe. At NAVS, we’re working toward a future where no cat spends their life in a laboratory.

For now, please enjoy this very important kitten business.

Keep the curiosity. Keep the hands-on learning. Rethink the dissection.

Five reasons to explore humane anatomy tools:
1. Physical models offer hands-on exploration.
2. Reusable tools let students return to a lesson.
3. Humane options can help students participate without compromising their values.
4. Effective alternatives support anatomy learning goals.
5. Replacing animal specimens spares animals.

NAVS’ BioLEAP Classroom Grants provide up to $1,000 in humane learning tools. Applications close November 8.

Animals suffer. Violations repeat. Where is the accountability?

Wisconsin Public Radio featured NAVS’ own Meredith Blanchard, director of advocacy and sanctuary, in a story examining animal welfare violations at UW-Madison’s primate research center.

Drawing on our 2026 Laboratory Animal Care Audit, the coverage highlights inadequate veterinary care, missed pain medication and unsafe conditions affecting monkeys used in research.

NAVS is bringing these records into public view and pressing for meaningful accountability. Thank you to Wisconsin Public Radio for covering this critical issue.

Questionable soccer skills. Excellent priorities.

More room to run. More time to play. A life beyond a laboratory.

That’s the future NAVS is working toward for every dog!

One year ago, we launched a bold vision for a future without animal experimentation.

Today, as we celebrate the first anniversary of Crossroads 2029: The Shift to Science Without Suffering, we're seeing encouraging signs of progress.

Federal agencies are investing in human-based research, advancing non-animal testing methods, and beginning to rethink long-standing reliance on animal experiments.

But there's still much more to do. Progress is not the same as transformation. Animals continue to be used in research, and meaningful change requires more than promises.

That's why NAVS is tracking federal agency commitments, demanding accountability, and advocating for science that's better for people and animals.

One year in, we have reason to be hopeful and every reason to remain determined.

Through the 2025 NAVS BioLEAP Classroom Grant, Andrea Anders of Chicago Vocational Career Academy transformed anatomy education for 150 ninth-grade biology students by replacing animal dissection with humane, hands-on learning tools.

Using BioLEAP grant funding, Andrea introduced life-sized fetal pig anatomy models featuring removable organs and body systems. Students worked collaboratively to explore anatomical structures, investigate organ systems, and understand how the body's systems function together—all without the use of animals.

The results were remarkable. Students achieved learning outcomes equal to or better than previous classes that used traditional dissections, participation increased, and more students felt comfortable engaging in classroom activities. The implementation of these humane alternatives also spared 20 fetal pigs.

Perhaps most importantly, every student was able to fully participate. By removing barriers associated with animal dissection, the classroom became a more inclusive, engaging, and effective learning environment.

Science education can be rigorous, hands-on, and humane.

We walked together. We raised our voices. And we left knowing the animals were still inside.

NAVS joined advocates at the opening and closing events of the March to Abolish Animal Testing, a 207-mile journey across New York that ended outside Marshall BioResources.

This reel captures the compassion and determination that brought us together. Now, help carry that commitment forward.

What do compassion and good science have in common? More than many people realize.

NAVS Director of Policy and Advocacy Meredith Blanchard recently joined Northern Spirit Radio to discuss the problems with relying on animal testing, the policies that have allowed it to persist and the promising human-relevant methods helping create a better future for science.

Thank you to Northern Spirit Radio for giving NAVS the opportunity to share why advancing humane science is better for animals and people.

Fourteen pigs rescued from a research laboratory are beginning a new chapter thanks to “Mission Pigpossible,” a remarkable effort coordinated by New Life Animal Sanctuary.

The complex rescue brought together volunteers from across the Midwest to transport the pigs to five sanctuaries in four states. New Life temporarily cared for four of them as they awaited transportation to their permanent homes.

NAVS is proud to support New Life Animal Sanctuary through a grant from our Animal Sanctuary Assistance Program (ASAP), helping provide the care these pigs need as they transition to sanctuary life.

While little is known about what they experienced before their rescue, their future will be defined by safety, care and the freedom to live on their own terms.

Please join us in celebrating everyone who made this rescue possible and the pigs who get a chance at a life of love and freedom.
