Estray Livestock Laws in Maine: What You Must Do When You Find Stray Animals

Spotting a loose cow ambling along a rural road or a horse grazing in your backyard is not an unusual experience in Maine’s farming communities. When it happens, most people’s first instinct is to help — but the law has specific expectations about what you can and cannot do next. Maine’s estray livestock statutes set out a clear process for how stray farm animals must be handled, who bears the cost of care, and what happens if no owner ever comes forward.

Whether you are a rural landowner, a farmer whose animal has escaped, or simply a neighbor who spotted something unexpected in a field, understanding these rules protects you legally and ensures the animal is treated humanely. This guide walks you through every stage of the process under Maine law, from the moment you find a stray animal to the point where ownership is formally resolved.

What Is an Estray and How Maine Law Defines It

The word “estray” comes from common law and refers broadly to a domestic animal found wandering at large whose owner is unknown. In common law tradition, an estray is any domestic animal found wandering at large or lost, particularly if its owner is unknown — and in most cases, this implies domesticated animals rather than pets. Maine law uses the term “stray livestock” rather than “estray,” but the legal concept is the same.

Maine’s Animal Welfare Act provides a precise statutory definition of livestock. Under Title 7, Section 3907, “livestock” means cattle; equines; sheep; goats; swine; domesticated cervids, fowl and rabbits; members of the family Camelidae, genus lama and genus vicugna; bison; and ratites. This means animals like horses, donkeys, cows, pigs, chickens, ducks, llamas, alpacas, and bison all fall within the livestock category for estray purposes.

Two important exclusions apply. For purposes of the stray livestock statute, “livestock” does not include feral swine or domesticated cervids. So if you encounter a feral pig or a farmed deer wandering loose, those animals are governed by separate provisions. Likewise, companion animals like dogs and cats follow entirely different statutes under Maine law.

The law also defines what “stray” means. Under Maine statute, “stray” means off the owner’s premises and not under the control of a person. That single sentence carries real weight: an animal does not need to be injured, distressed, or far from home to qualify as a legal stray. If it is off the owner’s property and no person is actively controlling it, the estray process applies. You can find additional context on how Maine treats animal ownership and control in the state’s goat ownership laws and backyard chicken laws.

Your Obligations When You Find Stray Livestock in Maine

Finding stray livestock puts you in a position where inaction is not a neutral choice. Maine law does not permit you to simply ignore a stray cow or sheep, nor does it allow you to take informal possession and keep the animal without following the proper process.

The core rule is straightforward: if the ownership of any stray livestock cannot be established, the livestock must be handled as a stray and an animal control officer shall seize, impound or restrain the livestock and deliver it to an animal shelter, farm or holding facility that is capable of safely containing the number, type and size of the livestock. In other words, the moment you determine that ownership is unknown, the matter moves to official hands.

Your practical obligation as a private citizen is to notify authorities rather than to take custody yourself. Do not attempt to claim the animal as your own, sell it, or make permanent arrangements for it. A person taking up an estray has only a qualified ownership in it, which becomes absolute only if the owner fails to claim the animal within the statutory time limit. Acting outside those boundaries could expose you to legal liability.

Pro Tip: If stray livestock poses an immediate road hazard, call 911 first. Law enforcement can respond quickly to prevent accidents while the animal control process gets underway.

One related rule worth knowing: Maine law defines a “keeper” as a person in possession or control of a dog or other animal, and a person becomes the keeper of a stray domesticated animal, other than a dog or livestock, if the person feeds that animal for at least 10 consecutive days. Livestock are explicitly excluded from this keeper rule, which reinforces that you cannot casually acquire legal responsibility over a stray farm animal simply by feeding it. The formal estray process governs instead. For comparison, see how Maine handles similar animal-at-large situations in its leash laws and dog leash laws.

How to Report an Estray to Authorities in Maine

Reporting stray livestock in Maine means contacting your local animal control officer (ACO). Animal control officers are employed by a municipality and are not state employees; the ACO’s primary responsibility is to enforce the municipal animal control duties in Title 7 and Title 17. Because livestock estrays fall under Title 7, Section 4042, the ACO is the right first call in most situations.

Finding your local ACO is straightforward. Each of the 496 municipalities in Maine is required to employ an animal control officer, though many ACOs are employed by more than one town, resulting in over 300 animal control officers throughout the state. Your town office, municipal website, or local police non-emergency line can direct you to the right contact quickly.

In addition to the ACO, Maine’s state-level enforcement structure includes humane agents. A State Humane Agent is employed by the State of Maine, and as a state employee, a State Humane Agent’s primary responsibility is to enforce the animal cruelty statutes in Title 7 and Title 17. If there is any sign that the stray animal has been neglected, injured, or abandoned under circumstances suggesting cruelty, contacting the Maine Department of Agriculture, Conservation and Forestry (DACF) Animal Welfare Program is also appropriate.

When you make the report, be as specific as possible. Note the species and approximate number of animals, their location, any visible identification such as ear tags or brands, and whether the animals pose a road or safety hazard. This information helps the ACO respond with the right equipment and arrange a suitable holding facility. In Maine, other agencies including municipal animal control officers, sheriff departments, and the State Police also handle animal welfare complaints, so if you cannot reach an ACO immediately, local law enforcement is a valid alternative contact.

For livestock found in Maine’s unorganized territories — remote areas without an incorporated municipality — the rules still apply. For purposes of the stray livestock statute, “municipality” includes a county under Title 30-A, section 7501 if the stray livestock has been found in the unorganized territory of that county. Contact the relevant county office if you are unsure which jurisdiction applies.

Care and Cost Responsibilities While Holding an Estray in Maine

Once an animal control officer takes custody of stray livestock, the municipality assumes a defined set of responsibilities. The law does not leave the standard of care to guesswork.

A municipality shall retain custody of stray livestock for a period of 10 days, and the municipality is responsible for ensuring the proper care of the livestock while confined, including providing proper sustenance, shelter and necessary medical care. This means the municipality — not the finder, and not a private farmer who happens to house the animal — bears the legal duty to keep the animal healthy and safe during the holding period.

Maine law also anticipates that municipalities will often rely on third-party facilities to house farm animals, since most municipal facilities are not built to hold cattle or horses. A municipality may reimburse a farm, holding facility or animal shelter for the care and housing of stray livestock at the same rates as in section 3919-C. Section 3919-C governs reimbursement rates for animals held pending court decisions, and those same rate structures apply here.

Key Insight: If you voluntarily agree to house stray livestock on your farm while the ACO process unfolds, get written confirmation from the municipality that your costs will be reimbursed. Verbal agreements are harder to enforce when it comes time to settle the bill.

The law also addresses emergencies. Maine law provides for euthanasia of severely sick or severely injured stray livestock authorized by a veterinarian, humane agent, animal control officer or animal shelter. This provision ensures that suffering animals are not left in distress simply because an owner has not been identified. Additionally, Maine law provides immunity for a municipality, veterinarian, humane agent, animal control officer and animal shelter in instances involving the handling of stray livestock. Good-faith actors following the proper process are protected from civil liability.

If you are a livestock owner concerned about your animals’ welfare while in transit or under state oversight, Maine’s livestock transport laws in other states offer useful comparison points, and Maine’s own animal health statutes and rules govern disease control and care standards that apply to impounded animals as well.

How Livestock Owners Can Reclaim an Estray in Maine

If your animal escapes and ends up in municipal custody, acting quickly is essential. Maine’s 10-day holding window is firm, and the clock starts the moment the animal is impounded — not when you find out about it.

To reclaim your animal, you will need to provide reasonable evidence of ownership. Useful documentation includes:

• Brand registration records or photographs showing your brand on the animal
• Ear tag numbers matched to your farm records
• Veterinary records, purchase receipts, or registration papers
• Photographs of the animal taken before it went missing
• Microchip records, if applicable

If the owner reclaims the estray, they are liable for reasonable costs of its upkeep. That means you will owe the municipality or holding facility for feed, shelter, and any veterinary care provided during the impoundment period. Prompt reclamation keeps those costs lower.

The older common law framework that once governed estray notices in Maine has been substantially updated. Maine Revised Statutes Section 1052, which previously governed formal estray notice procedures, was repealed as part of the 2019 civil animal welfare law update. Today, the process flows through the ACO and municipal system rather than through a town clerk filing. Contact the municipality or the holding facility directly to begin the reclaim process.

Owners of livestock that travel across state lines should also be aware of how neighboring states handle strays. For reference, see how Idaho, Colorado, and Kentucky regulate livestock transport and stray situations. Maine’s pet vaccination laws are also relevant if your reclaimed animal needs updated health documentation before returning to your property.

What Happens When an Estray Goes Unclaimed in Maine

When no owner comes forward within the statutory period, Maine law provides a clear resolution. If ownership of the stray livestock is not claimed by any person, after 10 days, ownership of the livestock vests with the municipality or an animal shelter designated by the municipality, and the municipality or designated animal shelter may sell, adopt, give away or humanely euthanize the stray livestock.

This is a meaningful transfer of legal title — not a temporary arrangement. Once the 10-day window closes without a claim, the original owner loses all legal right to the animal. The municipality or designated shelter then has full discretion to determine the animal’s future, whether that means placing it with a new farm family, selling it at auction, or, in cases of severe illness or injury, humane euthanasia.

The range of outcomes available to the municipality reflects practical realities. A healthy dairy cow or a well-trained horse has real market value and is likely to be sold or rehomed. An animal in poor health may require a different outcome. When public officials impound stray animals, they may sell them at auction to recover the costs of upkeep, with proceeds, if any, going into the public treasury.

Common Mistake: Some livestock owners assume they can reclaim an animal after the 10-day window by simply showing up and proving ownership. Under Maine law, that right expires when the holding period ends. If you miss the deadline, the municipality legally owns the animal.

For livestock owners, the best protection against this outcome is prevention: secure fencing, proper identification on all animals, and a good relationship with your local ACO so that any escape is flagged to you quickly. Maine’s roadkill laws and hunting laws also touch on situations where livestock and wildlife interact on public roads and rural land, and understanding the full picture of Maine’s animal statutes helps you stay ahead of potential problems.

Ultimately, Maine’s estray livestock framework balances the rights of animal owners with the community’s need to handle stray farm animals safely and humanely. The 10-day window is tight but fair — it gives owners a reasonable chance to act while ensuring that animals do not languish indefinitely in municipal custody. Knowing the rules before you need them is the most practical step any Maine farmer or rural landowner can take.
