Alley Cat Allies and Local Partners Challenge Lethal Removal of San Juan’s Paseo del Morro Cats, Advocate for Humane Solutions

August 7, 2026

Alley Cat Allies is actively engaged on the ground in San Juan, Puerto Rico, spearheading a critical effort to protect the community cats residing in the historic Paseo del Morro. The organization, alongside local advocacy group Save A Gato, is implementing lifesaving measures to counter a directive from the U.S. National Park Service (NPS) for the lethal removal of these cats. This intervention follows a federal judge’s decision that Alley Cat Allies contends misrepresents evidence-based humane population control methods, specifically Trap-Neuter-Return (TNR), and permits NPS to contravene federal law in its planning. Beyond the immediate crisis at the Paseo del Morro, Alley Cat Allies is collaborating with Puerto Rican officials and animal welfare advocates to foster the broader adoption of TNR and enhance protections for cats across San Juan.

Escalating Conflict at the Paseo del Morro

The situation at the Paseo del Morro, a significant historical and tourist site within San Juan, has become a focal point for the ongoing debate surrounding the management of community cat populations on federal lands. For years, a colony of cats has thrived in the vicinity of the old city walls, a presence that has been managed by local caretakers and, more recently, with the support of Alley Cat Allies and Save A Gato.

The U.S. National Park Service, however, has asserted that the cats pose a threat to the natural environment and are therefore subject to removal. This stance culminated in a federal judge’s ruling, which, according to Alley Cat Allies, inaccurately portrayed the efficacy and ethical considerations of TNR. TNR is a widely recognized and scientifically supported method of humane population control for community cats, involving the trapping of unowned cats, sterilizing them, vaccinating them against rabies, and returning them to their original territory. This process, when implemented correctly, stabilizes and eventually reduces the population while preventing the suffering associated with uncontrolled breeding and disease.

Alley Cat Allies argues that the judge’s decision was based on flawed premises and did not adequately consider the established humane practices that have proven effective in numerous other locations. The organization has initiated all available legal avenues to challenge this ruling, emphasizing that the core principles and scientific validity of TNR were not subject to a fair trial. Furthermore, they allege that the NPS’s removal plan was developed in violation of federal environmental and animal welfare laws, lacking thorough consideration of less harmful alternatives and failing to engage in comprehensive public consultation.

A Coalition for Humane Management

In parallel with the legal challenges, Alley Cat Allies has forged strong partnerships with key stakeholders in Puerto Rico. This includes collaborating with local leaders such as Congressman Pablo José Hernández, who has publicly voiced his opposition to the NPS’s proposed lethal removal strategy. Congressman Hernández has been a vocal proponent of humane approaches and has actively engaged with both the NPS and animal welfare organizations to find a more compassionate resolution.

The organization is also providing significant financial and logistical support to expand TNR initiatives throughout San Juan. This commitment extends to funding vital spay and neuter surgeries, ongoing TNR efforts in various neighborhoods, and comprehensive humane education campaigns. These campaigns aim to foster a deeper understanding and appreciation for community cats among residents and visitors, promoting coexistence and responsible stewardship. The goal is to create a sustainable framework for managing cat populations that prioritizes animal welfare and aligns with community values.

Congressman Hernández’s Stance on Humane Solutions

Congressman Pablo José Hernández has been a prominent voice advocating for a humane approach to the management of the Paseo del Morro cat colony. His office has been instrumental in facilitating dialogue between Alley Cat Allies, Save A Gato, and relevant government agencies.

"The NPS plan is both inhumane and counter-productive, and my constituents know it," stated Congressman Hernández in a recent statement. "I urge NPS to commit to a period of public outreach and stakeholder consultation to reach a solution that puts people and animals first."

This statement underscores the growing sentiment among local representatives and the public that lethal methods are not only ethically questionable but also ineffective in the long term for managing community animal populations. Congressman Hernández’s call for public outreach and consultation highlights a critical element often missing in such disputes: inclusive decision-making that respects the concerns of all parties involved.

Supporting Data and the Science of TNR

The efficacy of Trap-Neuter-Return (TNR) as a humane and effective method for managing community cat populations is supported by a growing body of scientific evidence and practical application across the globe. Unlike traditional catch-and-kill programs, TNR focuses on stabilizing and reducing populations over time by preventing further reproduction.

Key benefits of TNR include:

• Humane Population Control: TNR directly addresses the root cause of population growth by sterilizing cats, preventing unwanted litters, and reducing the number of cats entering shelters. Studies have consistently shown that TNR programs lead to a decrease in the number of cats over time, often to a point where the colonies are self-sustaining at a stable and manageable level.
• Improved Animal Welfare: Cats in TNR programs are vaccinated against rabies, a critical public health measure. They also receive veterinary care during the trapping and sterilization process, improving their overall health and reducing the spread of disease within the colony and to other animals.
• Reduced Public Nuisance: By stabilizing populations and preventing territorial disputes that often lead to yowling and fighting, TNR can reduce common nuisance behaviors associated with unmanaged cat colonies.
• Cost-Effectiveness: While initial investment is required, long-term TNR programs are often more cost-effective than repeated euthanasia and removal efforts. The costs associated with impoundment, euthanasia, and disposal can be substantial, especially when populations are not effectively controlled at their source.
• Ethical Considerations: TNR aligns with evolving ethical standards for animal treatment, recognizing the intrinsic value of animal life and promoting compassion. It avoids the suffering and death associated with lethal removal methods.

Data supporting TNR:

• A study published in the Journal of Applied Animal Welfare Science found that TNR programs led to significant reductions in cat populations and euthanasia rates in various municipal shelters.
• The American Veterinary Medical Association (AVMA) has recognized TNR as a viable and humane method for managing free-roaming cat populations.
• Numerous cities and counties across the United States have adopted TNR policies and seen positive results in terms of reduced shelter intake and euthanasia. For example, cities like Austin, Texas, and San Francisco, California, have implemented comprehensive TNR programs for community cats with demonstrable success.

The NPS’s plan, which reportedly does not prioritize TNR, runs contrary to these established best practices and the scientific consensus on effective and humane community cat management. The mischaracterization of TNR in the legal proceedings is a significant concern for animal welfare advocates who rely on its proven track record.

Broader Implications for Animal Welfare Policy

The situation at the Paseo del Morro has far-reaching implications for how community cats are managed on public lands and in urban environments across the United States and its territories. Alley Cat Allies’ fight is not just about the cats in San Juan; it is about setting a precedent for humane policies nationwide.

Key implications include:

• Federal Land Management Policies: The outcome of this legal challenge could influence how federal agencies, such as the NPS, approach the management of wildlife and animal populations on lands under their jurisdiction. A victory for humane advocacy could lead to a greater adoption of evidence-based, non-lethal methods across all federal lands.
• Judicial Interpretation of Animal Welfare Laws: The legal arguments presented in this case may shape how future judicial decisions interpret existing animal welfare laws and regulations, particularly concerning the rights and protections afforded to community animals.
• Public-Private Partnerships: The success of Alley Cat Allies and Save A Gato in mobilizing resources and advocating for their cause highlights the crucial role of non-profit organizations and community volunteers in supporting governmental animal management efforts. It underscores the potential for effective collaboration between public agencies and private advocates.
• International Standards: As San Juan is a U.S. territory, the approach taken here can also serve as a model or cautionary tale for other jurisdictions grappling with similar challenges, potentially influencing international standards for animal welfare.
• Community Engagement: The emphasis on public outreach and stakeholder consultation, as called for by Congressman Hernández, is a vital component of successful animal management. Engaging the community ensures that solutions are not only effective but also socially responsible and ethically sound.

Alley Cat Allies remains committed to a protracted legal and advocacy effort, aiming to secure a future for the Paseo del Morro cats that is both humane and sustainable. Their work in San Juan exemplifies a broader movement towards compassion and evidence-based practices in animal welfare, challenging outdated and inhumane approaches to community animal management. The organization is actively encouraging supporters to learn more about the situation and to engage with their elected officials to advocate for humane policies.
