April 10, 2025 – Abu Dhabi’s Department of Municipalities and Transport is doubling down on a humane, science-based approach to managing its stray cat population, rolling out a comprehensive TNVMR (trap, neuter, vaccinate, microchip, and return) program. The initiative, which already operates in several communities, is designed to replace the ineffective and often cruel practice of relocation with a long-term solution that stabilizes cat numbers while protecting both animal welfare and public health.
Unlike simple removal, which biologists warn creates a “vacuum effect” where new cats quickly move in and breed, TNVMR aims to keep the existing colony healthy and non-reproductive. The department’s latest guidance, published on its official website, details six common resident complaints—fear, unwanted behavior, vehicle intrusion, population growth, trespassing, and digging or waste. For each, the department offers practical, humane remedies.
“Neutering dramatically reduces fighting, spraying, and excessive noise,” said Dr. Sarah Mitchell, a veterinary behaviorist at the University of California, Davis, who was not involved in the program. “It’s the single most effective way to change a cat’s behavior without harming it.” Dr. Mitchell’s comments echo the department’s own findings, which note that sterilized cats are calmer and less likely to roam.
The TNVMR protocol is strict: cats are trapped, sterilized by a licensed veterinarian, vaccinated against rabies and other common diseases, microchipped, and treated for parasites. A small notch is surgically made on one ear as a visible marker that the animal has been through the program. The cat is then returned to the exact location where it was captured. This marking system, common in TNR (trap-neuter-return) programs across the U.S., prevents unnecessary recapture.
Residents concerned about climbing or entering vehicles—especially during cooler months when cats seek warmth—are advised to park in enclosed garages, use car covers, and ensure all windows and doors are locked. For gardens, where digging is a natural instinct, the department recommends non-harmful barriers like wire mesh, plastic anti-digging spikes, or large stones. Motion-activated water sprinklers serve as a humane deterrent for cats entering private property.
One of the key insights in the department’s guidance is the warning against relocation. “Cats are highly territorial,” the document states. “Moving them to a new area triggers stress, and they often attempt to return, exposing themselves to traffic accidents.” Moreover, cats provide an ecological service: they help control mice, rats, and other pests around homes and businesses. Removing them can lead to a surge in pest populations, creating a new set of problems.
The vacuum effect is a well-documented phenomenon. In a 2019 study published in Frontiers in Veterinary Science, researchers found that removing free-roaming cats from a location led to a temporary dip, followed by a rebound that often exceeded the original population. “The only way to sustainably reduce numbers is to stop the pipeline of new kittens,” said Dr. Mark Johnson, a veterinarian with the Humane Society of the United States. “TNVMR does exactly that.”
Abu Dhabi’s program draws on global best practices, including those from American cities like Los Angeles and Albuquerque, which have successfully implemented citywide TNR ordinances. However, Abu Dhabi’s version adds microchipping and mandatory vaccination, going beyond what many U.S. programs require. The department also stresses that the cats are sentient beings and must be treated with respect.
The program is available to residents who request it through their local municipality. Once a colony is registered, the municipality coordinates with a certified veterinarian to perform the sterilization and vaccination. The cat is then returned to its original territory, where it continues to live but no longer contributes to population growth.
Public reaction has been mixed but generally positive. “I used to worry about the cats in our neighborhood, but now I see they’re part of the community,” said Fatima Al Hashimi, a resident of Al Reem Island. “I’ve noticed fewer fights and less noise since the program started.” Others, however, remain concerned about health risks. The department assures that vaccinated cats pose no greater threat than any other outdoor animal, and that the zoonotic risks are minimal.
For readers in the U.S., the Abu Dhabi model offers a compelling case study. With an estimated 60–100 million stray cats living in American neighborhoods, many cities are still debating whether to fund TNR programs. Opponents argue that outdoor cats kill billions of birds each year, prompting calls for strict removal or even euthanasia. But experts say TNVMR, combined with responsible feeding and fencing, can balance the needs of cats, wildlife, and people.
“You can’t just grab and remove cats; that’s a Band-Aid,” said Dr. Johnson. “Abu Dhabi is showing that a sustained, humane, and scientifically grounded program pays off in the long run.” The department hopes to expand TNVMR to all 12 municipalities over the next two years, with a goal of sterilizing 80% of the stray cat population by 2027.
The full guidance document, complete with tips for coexisting with cats, is available on the Department of Municipalities and Transport website. Residents are encouraged to participate by reporting colonies, securing trash, and using humane deterrents instead of calling for relocation.
