A Closer Look at How S.P.O.T. and Targeted TNR Support Cat Colonies

When the Humane Society for Tacoma & Pierce County (Tacoma Humane) launched a fundraising campaign to bring a mobile veterinary and outreach vehicle to life, the community responded with overwhelming support. 

Generous donors contributed nearly $400,000 to realize our shared vision of reaching underserved neighborhoods with on-the-ground animal care. This vision became a reality with the mobile veterinary unit, S.P.O.T. 

Launching this effort during a national shortage of veterinary professionals came with significant challenges: the vehicle’s arrival was delayed, additional equipment needed to be ordered and installed, and hiring a skilled and compassionate team took time. But building this program thoughtfully was essential. S.P.O.T. wasn’t built to be a quick fix. It’s a long-term investment in a more equitable system of care—one that centers pets, people, and places often overlooked. 

What is S.P.O.T.? 

S.P.O.T. stands for Spay, Preventative Medicine, Outreach, and Transport—a veterinary suite on wheels operated by Tacoma Humane. Its primary focus is on tackling the community cat overpopulation in Pierce County. However, we’ve been able to expand the use of the vehicle in an effort to remove barriers to care by offering affordable services and expanding pet ownership through

• Core vaccinations 
• Microchipping 
• Flea and internal parasite treatments 
• Pet food support 
• Humane education and resources 

• Mobile adoption events
• Spay/neuter surgeries and wellness support for community cats 

Why Does Pierce County Need S.P.O.T.? 

For many residents across Pierce County, especially in rural or under-resourced neighborhoods, basic veterinary services are simply out of reach. Pet owners and community caregivers face barriers ranging from lack of transportation to the absence of nearby veterinary clinics, compounded by other systemic challenges.  

When access is limited, pets go unvaccinated and unaltered, not because of neglect, but because help isn’t readily available. Stray animal populations are growing, and shelters are becoming overwhelmed.  

S.P.O.T. was created to meet these challenges head-on. 

S.P.O.T. is Tacoma Humane’s door into our community, offering community outreach and a Targeted TNR program. 

What is Targeted TNR? 

S.P.O.T. has focused on Targeted Trap-Neuter-Return (TNR) since its first official outreach in September 2025. This is a humane, data-driven approach to managing outdoor cat colonies through sterilization that will over time reduce intake of community cats into the shelter. 

Cat colonies are groups of free-roaming, unowned cats who live together in places such as alleyways, abandoned buildings, mobile home parks, industrial sites, farms, barns, or other places where they’ve established a home and rely on consistent access to shelter and food. These cats are typically cared for by a local resident (who we refer to as a “community caregiver”) who provides food and basic oversight. While many cats are socialized to humans, many are feral or semi-feral and not suited for indoor adoption.  

During the September launch, the team served three separate colonies within the same neighborhood. After weeks of careful planning, coordination, and trapping, they reached over 90% sterilization, with a goal to return to sites and trap the remaining few cats, along with any new additions, at each site to complete 100% sterilization.  

Targeted TNR aligns with best-practice guidance from the Association of Shelter Veterinarians, which recommends using population-level data and return-to-field programs for healthy community cats to reduce intake pressure and focus shelter resources on animals most in need.

How Does Targeted TNR Work? 

Targeted TNR uses data to zero in on high-impact areas. Heat mapping, shelter intake data, and community reporting help identify colonies most in need. S.P.O.T. then works alongside community caregivers and partners to trap, sterilize, vaccinate, and return cats to their home territory healthier and no longer contributing to population growth. 

Here is a general breakdown of how Targeted TNR works. 

1. Prioritize neighborhoods and zones with: 

• • High numbers of unaltered cats 

• • Frequent cat-related complaints 

• • High intake of feral/unsocialized cats or euthanasia rates  

By focusing on high-need zones, our community will receive maximum impact. 

2. Organize and begin systemic trapping 

Cats in the target area are humanely trapped through a coordinated effort to ensure as many as possible are spayed/neutered, vaccinated, and returned. This prevents a “vacuum effect” where unaltered cats from nearby areas move in to fill an open territory. The vacuum effect is an important consideration for community members who wish to remove a colony all-together, as this action is short-term and will ultimately result in a new colony. 

National guidance from Humane World confirms that returning sterilized cats to their original location is more effective at reducing community cat populations than removal, while large-scale sanctuary placement is rarely feasible or sustainable.

3. Quickly treat and return cats 

The cats are provided a basic wellness exam, anesthetized, spayed/neutered, vaccinated, and ear-tipped (a minor surgical procedure to remove the tip of one ear, which permanently identifies the cat as altered to prevent it from being re-trapped in the future). After recovery, they are returned to the exact location they were trapped. These cats already have a “home.”  Many of them are not socialized to humans and would not thrive in a traditional home setting. Achieving sterilization rates above 90% is critical because it stabilizes the colony and, through targeted “straggler days,” makes it much easier to identify and respond to a straggler—a non-ear-tipped cat—before the population can rebound, keeping the situation manageable over time. 

4. Monitor and engage the community 

Targeted TNR isn’t a one-and-done effort. It involves: 

• • Tracking progress in target areas through site visits and structured caregiver reporting 
  • Trapping missed cats 
  • Responding to new arrivals 
  • Continued community engagement 

Why Timing Matters
Cats can become pregnant as early as four to six months of age, and feline pregnancies last just about nine weeks. Because of this short reproductive cycle, even small gaps in care can quickly lead to new litters. Targeted TNR helps interrupt this cycle by reaching colonies quickly and thoroughly, reducing the number of kittens born outdoors and preventing rapid population growth. All of these activities help reduce new litters of kittens born outdoors, stabilizes or shrinks outdoor cat populations over time, decreases shelter intake of cats who already have a home outdoors, and improves the health and behavior of colony cats. 

What Does This Look Like in Action? 

To understand how S.P.O.T. delivers Targeted TNR, we spoke with community caregiver, Tami O. A resident of Lakewood, Tami found herself caring for dozens of outdoor cats in a fast-growing colony at a mobile home community. She is an attentive caregiver who has assisted with trapping cats and continues to care for them. She has also patroned our community clinic to get vaccines for her own cats and dog!

S.P.O.T. arrived at the site in which Tami provides care, and the team of Humane Society staff and volunteers coordinated the trapping and sterilization of over 45 cats in her community. They were treated for fleas, vaccinated, and safely returned—calmer, healthier, and part of a now-manageable colony. 

“I have lived in this trailer park for three years. Quickly, I noticed a lot of stray and feral cats in the park. Most were hungry and sick. The cats were breeding nonstop. The kittens were sick and some of the momma cats were abandoning them. I started feeding them and caring for the abandoned kittens. I brought several kittens to the shelter. I was concerned that the cycle of sick and dying cats would continue…Tacoma Humane’s S.P.O.T. van came to the park and spayed and neutered about 30 cats and older kittens. The cats were also given shots and flea medicine. If they were sick, antibiotics were given. I was so overjoyed I cried. The animals here are now fed on a regular basis and they are much healthier. 

I hope that this program continues. It will save lives and decrease the number of feral and stray cats that are brought into the shelter and decrease the overwhelming number of cats in the community. 

Thank you so much for all you do for the animals in Lakewood and Tacoma.”

What Has Been the Impact? 

S.P.O.T. provides so much more than the critical Targeted TNR. The vehicle has hit major milestones: 

• • Completed 74 spay/neuter surgeries with another outreach event scheduled in early February 
  • Achieved 93% sterilization at a site housing three colonies 
  • Hosted 4 off-site kitten adoption events
  • Humanely euthanized one cat when its suffering could not be relieved (learn more)  
  • Prioritized helping cats stay with caregivers whenever safe and possible through shelter diversion 
  • Continued coordination with animal control to reduce unnecessary shelter intake 

What’s Ahead? 

Effective outreach isn’t about “rescuing” from the outside, but rather empowering people within their own communities to identify, advocate for, and build sustainable solutions together. S.P.O.T. is scheduled throughout 2026 to offer on-site services and deepen relationships with neighborhoods that need them most.
