A complete 2026 resident guide to the limited-admission nonprofit on Diehl Road that matches companion animals with western suburbs families — and the many ways residents can help, even if they cannot adopt today.

The Naperville Area Humane Society (NAHS) at 1620 W Diehl Rd is a 501(c)(3) limited-admission animal shelter that has matched dogs and cats with western suburbs families since 1979. Adoption begins with an online application, then a whole-household meet-and-greet at the shelter on Diehl Road. Every pet goes home spayed or neutered, vaccinated, and microchipped. In 2026, Naperville residents can help in four ways:

• Adopt — Fees range from $0 (senior pets, Lucky 7 Fund) to $500 (puppies); start with the online application.
• Foster — Open your home for a few days to a few months; NAHS provides food, supplies, and partner-hospital vet care.
• Volunteer — In-shelter roles for ages 18+; the NAHS Junior Board welcomes high schoolers 15 and up.
• Donate or attend an event — Run Your Mutt Off 5K (June 13), Fore The Paws Golf (Aug 3), Black Cat Ball (Sept 25), Giving Tuesday (Dec 1).

A Local Mission Built Around Lasting Bonds

The NAHS mission is straightforward: to promote the humane treatment of companion animals and create lasting human-animal bonds. The accompanying vision is to engage people to compassionately and responsibly create a more humane world.

Those words are reflected in how the shelter operates day to day. Staff and volunteers care for each animal individually. The organization runs on community donations, partners with local businesses and schools across Naperville, Warrenville, and the rest of DuPage County, and operates as a thoughtful nonprofit rather than an emergency rescue.

You will not hear NAHS describe itself as a rescue, and that word choice is intentional. The shelter is limited-admission, meaning it can accept animals only as space and resources allow.

What to Know Before You Adopt at NAHS

The first thing to understand about adopting from the Naperville Area Humane Society is that the team treats it as a lifelong commitment.

NAHS does not do quick, walk-in adoptions. You’ll be asked to come in with a clear sense of your own lifestyle and to think honestly about what your family can offer a pet day after day. Every family member who lives in the home is asked to come to the meeting — including kids and any current pets, when appropriate.

“It’s a lifelong commitment. We just ask that any potential adopter come knowing their lifestyle, knowing what they can offer a pet, give them the best home possible.” — Christine Natarelli, Executive Director, Naperville Area Humane Society

Practical requirements are straightforward. Adopters must be at least 21 years old and bring a valid driver’s license or state ID along with proof of current address. The first step is filling out the online application on the NAHS website, especially for dogs. The application gives the team enough context to set up a scheduled meeting and, in some cases, to recommend a different pet who might be a better fit than the one your family had in mind.

Adoption fees in 2026 are set by age:

• Dogs. Puppies (2 to 11 months): $500. Adult dogs (1 to 6 years): $350. Senior dogs (7 and older): fee waived, courtesy of the NAHS Lucky 7 Fund.
• Cats. Kittens (2 to 11 months): $175 for a single or $250 for a pair. Adult cats (1 to 6 years): $125. Senior cats (7 and older): fee waived, also courtesy of the Lucky 7 Fund.

The fee covers significantly more than the animal itself. The next section breaks down exactly what is included.

What Happens Before a Pet Is Ready to Go Home

Animal welfare is at the core of everything the shelter does, and that shows up most visibly in the work that happens before an animal is ever listed for adoption.

Every dog and cat at NAHS receives:

• A full initial veterinary exam
• Spay or neuter surgery
• A microchip
• Age-appropriate vaccinations, including rabies when applicable
• A fecal test
• Deworming and flea treatment if needed

Dogs additionally get a heartworm test and first preventive (when age-appropriate), the DA2PPV combination vaccination, the Bordetella vaccination, and a collar to go home in. Cats also receive an FeLV/FIV test and the FVRCP combination vaccination.

Medical care is only half of the picture. Behavioral care and daily enrichment are taken just as seriously. Animal trainers work with the pets, and the animal care team builds enrichment activities into the daily routine to support each animal’s well-being.

“Beyond just medical care, we also take behavioral care and enrichment very seriously, because their well-being is much more than just the health as well.” — Christine Natarelli, Executive Director

Not every pet at NAHS finds a home immediately, and that is okay. The shelter continues to invest in each animal’s quality of life for as long as they are there. Trainers and animal care staff partner closely on individualized plans, including additional medical checks when needed.

NAHS also partners with local and national organizations to take pets offsite to community events when possible. Each appearance gives an animal a break from the shelter environment and exposure to new people.

Why Microchips Matter (and Why Yours Should Be Updated)

Every animal adopted from NAHS goes home microchipped. The chip itself does not broadcast a location, but it does carry a unique number that links back to the owner’s contact information in a registry.

That contact information is only as useful as it is current. Every time NAHS takes in an animal, the staff scans for a chip. If one is present and the registration is up to date, the team can call the registered owner and start the process of getting the pet home. If the registration is outdated, the trail goes cold quickly.

The takeaway for every pet owner in Naperville: if you have moved between neighborhoods, changed your phone number, or switched email addresses since your pet was chipped, log into the microchip registry and update your contact information today. It is one of the most important things you can do to protect your dog or cat — particularly if you live near Springbrook Prairie, the DuPage Riverwalk, or any of Naperville’s dog-friendly neighborhoods where off-leash moments can happen.

How to Help Beyond Adoption

Adoption is not the only way to support the animals at NAHS. Many meaningful contributions come from people who are not currently in a position to bring a pet home.

“After fostering for NAHS for three years, what struck me most is how much time the team spends getting to know each animal. They aren’t running a quick-adoption mill. They’re matching companions for life — and that matters, especially for families with young kids or other pets at home.” — Representative reflection from a long-time Naperville NAHS volunteer

“Anytime we could get an animal out of the shelter and into a home environment is super helpful.” — Christine Natarelli, Executive Director

Ways to make a difference:

• Fostering. Open up your home for as little as a few days or as long as a few months. Fosters welcome adult dogs, pregnant cats and dogs, moms with litters, orphaned puppies and kittens, and animals needing extra medical or behavioral support. NAHS provides food, supplies, and veterinary care through partner hospitals. Foster volunteers must be at least 18, have reliable transportation, and live in pet-friendly housing.
• Volunteering. Volunteer opportunities range from in-shelter roles to landscaping, handicraft, and event support. Most in-shelter roles require volunteers to be 18 or older. The NAHS Junior Board is open to high schoolers age 15 and up. For specific role descriptions, schedules, and orientation details, contact the Volunteer Coordinator at volunteer@naperhumane.org or (630) 420-8989 x1004.
• Donations, financial and in-kind. Cash donations help cover the medical and behavioral care every animal receives. Supplies on the NAHS wish list are welcome any day between noon and 5:00 p.m. For the current wish list and giving options, visit naperhumane.org.
• Pet therapy. Owners of well-behaved, certified therapy dogs or cats can participate in two NAHS programs. PAWSitive Pet Therapy teams visit senior centers, nursing homes, and other facilities across the western suburbs. Paws for Tales teams visit Naperville-area schools to help children read aloud to a friendly, non-judgmental animal. For requirements and current openings, contact the Pet Therapy Program Coordinator through the NAHS website.
• Corporate partnerships. Local businesses can explore the NAHS Corporate Partners program. Details are available on the NAHS website.
• Showing up online. Following NAHS on social media, sharing adoptable pet posts, and engaging with stories all help. Visibility is how animals find homes.

The Dog Day Out Program: How Volunteers Take a Shelter Dog Out for the Day

One of the most rewarding ways to volunteer at NAHS is the Dog Day Out program. Volunteers take a shelter dog out for the day, giving the dog a break from the shelter environment and exposure to new places and people.

Outings typically focus on trails, neighborhood walks, and quiet spots where the dog can meet people without the chaos of a dog park. Volunteers often head to the trail systems through Springbrook Prairie, the wooded paths around the DuPage Riverwalk, or quiet neighborhood sidewalks in Tall Grass or Cress Creek. The team intentionally avoids dog parks during these outings — for the right kind of off-leash energy, see our guide to dog parks in Naperville, IL.

The benefits run both ways. The dog gets enrichment and a change of scenery. And every additional person who meets a shelter dog in the community is another potential adopter — or another voice spreading the word.

For Dog Day Out eligibility, scheduling, and sign-up, contact NAHS through the volunteer coordinator.

What Makes NAHS Different from a Rescue?

Plenty of shelters and rescues in the Chicagoland area place animals into homes. What makes the Naperville Area Humane Society different is the depth of attention each individual animal receives — and the deliberate choice to call itself a limited-admission shelter rather than a rescue.

“We really do specialize in individual care. Every animal that comes in, we take a lot of time to evaluate them, get to know them, and adjust what we need to do to give them the best care possible. We’re not here just to do quick adoptions. We truly are here to make sure that it’s the perfect fit for both the family or the person and the pet.” — Christine Natarelli, Executive Director

That philosophy shapes the whole experience: the unhurried adoption process, the time spent matching the right pet to the right household, the depth of medical and behavioral preparation, and the long-term commitment to each animal until the right home is found.

It is not the fastest way to run a shelter. It is the way that produces the lasting bonds the mission talks about.

NAHS is a limited-admission shelter, which means it accepts animals as space and resources allow and commits to each animal’s quality of life for as long as they are in the shelter.
