Can You Keep a Stray Cat in Hawaii? What State and County Law Says
October 31, 2026
Stray cat laws in Hawaii are not written in one tidy statute. State law sets the base rules for animal control, cruelty and microchipping, and each county adds its own pound, impound and feeding rules on top. That means the right answer for a cat in Hilo can differ from the answer in Honolulu.
The good news is that the legal picture for an ordinary person who finds a lost or wandering cat is simple. Act in good faith, try to find the owner, and use your county animal agency or humane society. This article explains each step in plain English, from keeping a cat to feeding, trapping and reclaiming strays.
Stray Cat Laws in Hawaii: Quick Answer
Hawaii has no single statewide stray cat statute. Instead, county animal control agencies handle strays under chapter 143 of the Hawaii Revised Statutes and their own county codes. One 2026 state-by-state comparison lists Hawaii among the states with no specific feral cat law.
- Finding a cat: You may take in a stray, but you should try to locate the owner and tell your county animal agency or humane society.
- Keeping a cat: Treat it as a found pet first. Adopting it is the end of a process, not the start.
- Feeding: Hawaii County bans feeding stray and feral animals on county property. Private property is different.
- Abandoning: Dumping a cat is treated under animal cruelty and abandonment rules, not as a loophole.
Is a Stray Cat Legally Owned or Unowned in Hawaii?
A cat that has an owner stays legally owned even when it wanders. Losing track of a pet does not erase the owner’s rights. That is why you cannot treat a friendly, well-fed cat as free for the taking.
State harbor rules define a “stray” as an animal without a microchip or other registered owner identifier, or one roaming off its owner’s property without permission. The Hawaii Administrative Rules definition adds that strays may also be feral or abandoned. A stray is therefore often an owned cat that is lost, not an ownerless one.
A cat with no tag, chip, or claimant after a fair search is functionally unowned. Even then, the safest route is to let a shelter or animal agency document the cat first.
Stray vs. Feral vs. Community Cats Under Hawaii Law
Hawaii law does not give these three terms one uniform meaning. The state Department of Land and Natural Resources notes that feral cats are the same species as pet cats, separated only by lifestyle and behavior, according to the Hawaii Invasive Species Council.
| Term | Plain Meaning | Practical Effect |
|---|---|---|
| Stray | A cat without a registered owner identifier, or one roaming off its owner’s property | May be lost or abandoned; treat as a found pet |
| Feral | A cat living outdoors without a human owner, usually not socialized to people | Handled through county programs, trapping and sterilization |
| Community cat | An informal term for an outdoor cat cared for by neighbors, often in a managed colony | No statewide legal status; local rules on feeding apply |
Bills to create a registered-caretaker system for feral cats have been introduced in the legislature, such as HB409 in 2021, which would have exempted registered caretakers from feeding restrictions. The bill text shows the idea, but a bill is not law. For more on outdoor cats generally, see our guide to feral cat laws in Hawaii.
Can You Keep a Stray Cat in Hawaii?
Yes, in most cases you can end up keeping a stray cat, as long as you do it the right way. The key is that no owner comes forward and any required holding period at a shelter has passed.
If you simply take a cat into your home, you are holding someone else’s property until proven otherwise. A found-pet report protects you and the cat. Aloha Animal Alliance explains that filing a found report places the cat on official records, which helps reunite families.
Once you keep the cat, normal ownership duties apply. That includes microchipping and basic care, covered below. Landlord and housing rules can also limit what pets you may keep, so check your lease.
How Long Before a Stray Cat Is Legally Yours in Hawaii?
There is no single statewide countdown after which a found cat automatically becomes yours. What matters is the shelter’s stray hold, which is the legally required period that gives an owner a fair chance to reclaim a missing cat, as Aloha Animal Alliance describes it.
If you brought the cat to a shelter, it is the shelter’s hold that controls. If you are fostering the cat at home, the safest approach is to report the cat, search for the owner, and then ask your county agency or humane society how to finalize adoption. Many shelters give the finder a first right to adopt once the hold ends.
Pro Tip: Take dated photos of the cat, keep copies of your found-pet report and flyers, and write down every contact attempt. This record shows good faith if an owner appears later.
Are You Required to Look for the Owner of a Stray Cat in Hawaii?
No statute I could verify spells out a personal search checklist for a private finder. Still, looking for the owner is the legal and ethical baseline, because the cat may belong to someone.
A reasonable search takes only a few steps:
- Check for a collar, tag or ear notch.
- Have a veterinarian or shelter scan for a microchip, which Hawaii requires for owned cats over four months old under HRS 143-2.5, according to LegalClarity.
- Post photos on neighborhood groups and lost-pet pages.
- Put up flyers near where you found the cat.
- File a found report with your county animal agency or humane society.
What to Do When You Find a Stray Cat in Hawaii
Start by deciding whether the cat is friendly, injured or truly feral. A cat that avoids all contact and has a notched ear is likely part of a managed colony. The Hawaii Invasive Species Council points out that a notched ear signals a sterilized colony cat.
For a friendly or injured cat, keep it safe, get it scanned for a chip and report it. For a cat that appears feral, do not try to adopt it out of the wild. Contact a humane society about trapping and sterilization instead.
Never release a cat you have taken in. Aloha Animal Alliance advises that you should never abandon or release an unsterilized cat outdoors. If you have vaccination questions for a cat you keep, see our page on pet vaccination laws in Hawaii.
Does Hawaii Law Require Reporting a Found Cat to Animal Control or Police?
There is no police reporting duty for an ordinary found cat. The practical reporting channel is the county animal agency or the humane society serving your island, and Aloha Animal Alliance recommends reporting a found cat within the required timeframe, noting that laws vary by island.
Call police only for an injured cat in a dangerous place, suspected cruelty, or an aggressive animal. Otherwise, animal control or the local humane society is the right first call.
Stray Cat Holding Periods at Hawaii Shelters
Holding periods exist so owners can find their pets. They are set through county animal control programs operating under chapter 143 of the Hawaii Revised Statutes, and they vary by agency and by whether the cat is identified.
The Hawaii County Code, Chapter 4 authorizes the county agency to seize and impound stray cats and to dispose of them in line with chapter 143. For the exact number of days on your island, contact your county agency or humane society directly, since they publish the schedule they follow.
Cats with a microchip or tag are generally easier to return to an owner, which is why scanning matters.
Will Animal Control Pick Up a Stray Cat in Hawaii?
Counties have the authority to pick up strays, but service levels differ by island. The Hawaii County code allows its animal control agency to impound a cat or other domesticated animal that is a stray, including a cat wandering or running at large.
Healthy outdoor cats are often a lower priority than injured animals or dangerous situations. If a cat is hurt, say so clearly when you call. If it is healthy but unowned, ask about drop-off options and trap loan programs.
Rabies Vaccination, Licensing and Microchip Rules for Stray Cats in Hawaii
Hawaii is rabies-free, and its quarantine system is built around keeping it that way. That affects how you move cats between islands and out of state, so ask your veterinarian before you travel with a rescued cat.
On microchips, LegalClarity reports that HRS 143-2.5 requires cats over four months old to be microchipped and registered with current contact details. Licensing rules for cats are set at the county level, so check with your county before assuming a license is or is not needed.
Spaying and neutering is not a statewide legal requirement for adopted strays, though many counties reduce fees for sterilized pets. A 2025 bill, HB364, proposed sterilization within sixty days of taking ownership, but it is a proposal, not current law. See our overview of pet vaccination laws in Hawaii for related rules.
Is It Illegal to Feed Stray Cats in Hawaii?
Feeding a stray cat at your own home is not banned by state law. Feeding on public property is where the legal risk sits.
Hawaii County Ordinance 25-63, which took effect on January 1, 2026, prohibits feeding stray and feral animals, including cats, on county-owned or managed property such as parks and beaches, according to the American Bird Conservancy. Reporting on the bill states that violators face fines of up to $50 for a first violation and up to $500 for later ones.
State harbor rules also ban feeding and abandoning feral animals at small boat harbors, and state military property bans it entirely. Landowners can still feed cats on their own private property in Hawaii County.
Key Insight: The same act can be legal on your lanai and a fineable offense at a county beach park. Location decides the answer.
Do Hawaii Laws Make You Responsible for a Stray Cat You Feed?
No Hawaii statute I could verify says that feeding a stray makes you its legal owner. Still, the statutory definition of an owner for liability purposes is broad. Under HRS 142-74, as shown in the bill text for HB363, an “owner” means a person who owns, keeps, feeds, or harbors a dog or cat.
That language appears in the liability section for animals that injure property. In practice, a regular feeder who treats a cat as their own could be argued to be a keeper. If you want to avoid that, work with a rescue or humane society rather than informally feeding a cat that causes problems.
Trap-Neuter-Return Laws for Stray and Community Cats in Hawaii
Hawaii has no statewide TNR statute. Proposed bills, including HB2593 in 2018, would have created registered caretakers and a trap-sterilize-return process, but they did not become law.
Volunteers still do TNR in practice. The Hawaii Invasive Species Council notes that humane traps can be borrowed from the Hawaiian Humane Society on Oahu, and trapped cats can be brought there for sterilization and vaccination. The council recommends sterilized cats be kept as indoor pets or adopted, not re-abandoned.
TNR is also limited on certain property. Hawaii National Guard policy bans cat colonies and TNR programs on state Department of Defense installations, per its stray and feral animal policy. Feeding bans in Hawaii County can also affect colony caretakers working on county land.
Is Abandoning a Cat Illegal in Hawaii?
Yes. Abandoning a cat falls under Hawaii’s animal cruelty and neglect laws. LegalClarity cites HRS 711-1109, where misdemeanor charges can carry sentences of up to one year.
State small boat harbor rules add a specific bar: no pet owner may permit a cat to become a stray, per Haw. Admin. Rules 13-232-57. Dropping a cat at a park, harbor or remote area does not solve a housing problem. Surrender to a shelter instead.
Can Neighbors Complain About Stray Cats in Hawaii? (Nuisance and Property Damage)
Yes, neighbors can complain to the county animal agency about a roaming cat. Cats found wandering at large can be impounded under county code, and HRS 142-74 makes an owner liable in damages when a cat on private property without consent injures or destroys another person’s livestock or property.
That liability turns on proving who owns the cat. For an unowned stray, there may be no one to hold responsible, which is why complaints usually go to animal control. Our guide on a neighbor’s cat in your yard in Hawaii covers property complaints in more detail, and outdoor cat laws in Hawaii explains roaming rules.
Can You Trap, Relocate or Remove Stray Cats in Hawaii?
You can use a humane trap to catch a cat, but you cannot treat it like a pest and do whatever you like. Cruelty laws still apply, and a trapped cat left without food, water or shade in Hawaii’s heat creates separate exposure, as our trapping laws in Hawaii guide explains.
Relocating a cat to a new spot is a bad idea and can count as abandonment. The Hawaii County feeding ordinance does not prohibit trapping or seizing an animal, according to SFGate’s summary of the bill. The safest path is to hand a trapped cat to a humane society or animal agency.
Never trap a neighbor’s pet. If the cat has a collar, tag or chip, it is owned.
Stray Cat Laws by City and County in Hawaii
Hawaii is made up of four main counties, and each handles animal control differently. Here is how the sources I verified break down:
| Area | What Applies |
|---|---|
| Hawaii County (Big Island) | Chapter 4 of the county code authorizes impound of stray cats. Ordinance 25-63 bans feeding stray and feral animals on county property from January 1, 2026. |
| Honolulu (Oahu) | Hawaiian Humane Society provides trap loans and sterilization services for trapped cats. |
| Maui, Kauai | Run their own county and humane society programs; check with your local agency for holding and impound rules. |
| State property | State harbor rules and military policy ban feeding and abandoning on covered property. |
Local rules can be stricter than state rules, so the county agency is always your best source. The Hawaii County animal code is a good example of a local code that sits on top of state law. For livestock and other animals, see estray livestock laws in Hawaii.
Who Can Reclaim a Stray Cat in Hawaii, and Can the Owner Sue You?
The original owner can reclaim a cat, and showing proof of ownership such as vet records, photos or a microchip registration usually settles it. A shelter generally releases the cat to the owner who can prove the claim, often after paying impound or boarding costs.
An owner who appears after you took the cat in can ask for it back. Suing is unlikely when you acted in good faith, reported the cat, and handed it back promptly. Problems arise when someone hides a cat, ignores a clear owner or sells it.
If you already adopted a cat through a shelter after a legal stray hold, you are in a much stronger position than someone who kept a cat quietly at home. Keeping paperwork from the adoption protects you.
