Estray Livestock Laws in Oregon: What to Do When You Find Stray Cattle or Horses
July 7, 2026
Stumbling across a steer grazing in your hay field or a loose horse wandering along a rural road is not as uncommon as it sounds in Oregon. The state’s mix of open range counties, working cattle operations, and active equine farms means stray livestock turn up on private land with some regularity — and when they do, both the person who finds the animal and the animal’s owner have specific legal obligations to meet.
Oregon addresses this situation through a formal body of law known as the estray statutes, codified primarily in ORS Chapter 607. Understanding these rules protects you from liability, ensures the animal receives proper care, and gives the rightful owner a fair chance to reclaim their property before it is sold.
This guide walks through every stage of the estray process — from the legal definition of an estray to what happens when no one comes forward to claim the animal.
Important Note: Oregon Revised Statutes are published on a two-year cycle. The core estray provisions discussed here reflect ORS Chapter 607 as amended through 2009 (HB 3417) and carried forward in subsequent editions. Always verify the current text at the Oregon Legislature’s official site before taking legal action.
What Is an Estray and How Oregon Law Defines It
Oregon law uses a precise definition for the word “estray,” and it is narrower than most people expect. Under ORS 607.007, an “estray animal” means cattle or equines that are unlawfully running at large or being permitted to do so, or that are found to be trespassing on land enclosed by an adequate fence. In plain terms, the estray statutes in Oregon apply specifically to cattle and horses (including mules, asses, and other equines) — not to every farm animal that might wander off.
This distinction matters because ORS Chapter 607 defines “livestock” broadly to include animals of the bovine species, horses, mules, asses, sheep, goats, and swine, but the formal estray process under ORS 607.303 through 607.339 was narrowed by a 2009 legislative amendment to focus on cattle and equines specifically. Sheep, goats, and swine that are running at large may still trigger liability and confinement rules, but the step-by-step estray procedure — with its notice requirements, ODA investigation, and public sale — applies to cattle and equines.
The law also defines what it means to actually “take up” an estray. “Taking up” means the intentional exertion of control over an estray animal, including but not limited to the restriction of movement, holding under herd, feeding, pasturing, or sheltering of the animal. Once you take any of those actions, you have formally entered the estray process and the legal clock starts running.
It is also worth understanding where you stand geographically. A “livestock district” is an area where it is unlawful for livestock to run at large, while “open range” is an area where livestock may lawfully be permitted to run at large. Whether you are in a livestock district or on open range affects whether the animal is actually running “unlawfully” — and therefore whether it qualifies as an estray under the statute. Most incorporated cities in Oregon are automatically livestock districts, while large rural areas in eastern Oregon remain open range. If you are unsure of your county’s status, contact the Oregon Department of Agriculture (ODA) Livestock Identification Office.
Your Obligations When You Find Stray Livestock in Oregon
When you find cattle or horses running at large on your property — or on property you lawfully possess or control — Oregon law gives you the right to take them up, but it also immediately attaches obligations. You cannot simply pen the animal and wait indefinitely to see what happens.
A person who finds an estray animal unlawfully being permitted to run at large upon the premises of the person, or premises of which the person has lawful possession or control, may take up the animal if the owner of the animal is known to the person. If you already know who owns the animal, you must notify that owner directly. A person taking up an animal shall within five days give notice of the taking up by certified or registered mail addressed to the owner or person having control of the animal, and that notice must contain a concise description of the animal, including marks and brands, if any.
That written notice must also accomplish two additional things: it must state that the animal will be released to and sold by the State Department of Agriculture as an estray animal unless redeemed before sale, and it must state the date of taking up the animal and that the department may sell an unclaimed animal not less than 30 days and not more than 45 days after the date of taking up the animal.
Pro Tip: Document everything from the moment you take up an estray — photos of the animal, its brands or ear tags, the date and location of taking up, and copies of any notices you send. This documentation supports your cost recovery claim if the owner appears, and protects you if any dispute arises later.
One action you cannot take is simply keeping the animal as your own or selling it privately. Oregon law makes unauthorized use of a livestock animal a Class A misdemeanor, and a court may order a convicted defendant to pay restitution to the owner of the animal. The estray process exists precisely to protect the owner’s property rights while also compensating you for your reasonable costs.

How to Report an Estray to Authorities in Oregon
Regardless of whether you know who owns the animal, you must also loop in the Oregon Department of Agriculture. The ODA’s Livestock Identification Office manages estray investigations and coordinates the public sale process when an owner cannot be located.
To report found cattle or equidae, contact your local livestock inspector or call the ODA Livestock Identification Office within five days. Found or estray cattle or equidae must be contained before a brand inspector will come out to investigate. This means your first practical step — before making calls — is to secure the animal in a pen, pasture, or enclosure where it can be safely held.
The formal notice requirement runs on two parallel tracks. Any person taking up an estray animal shall, within five days, give written notice of the taking up to the State Department of Agriculture, and that notice shall include a statement of the description of the animal, including marks and brands or other identifying characteristics. The notice must also include the date of taking up and the current location of the animal.
A person taking up an animal shall, no later than five days after giving the notice provided under the statute, forward a copy of the notice to the department or give a copy of the notice to a brand inspector or other agent of the department. In practice, you can satisfy this requirement by handing a copy directly to a brand inspector if one is available in your area, which is common in eastern Oregon ranching communities.
Once the ODA receives your notice, it begins its investigation. The State Department of Agriculture, upon receiving a notice as described in ORS 607.313, shall attempt to determine the owner of the estray animal from the recorded brand, marks, other identifying characteristics, and other relevant information tending to establish ownership. Brand records are a primary tool here — Oregon maintains a state brand registration system that allows inspectors to match a recorded brand to a registered owner.
| Step | Who Acts | Deadline |
|---|---|---|
| Contain the animal | Person taking up | Immediately upon taking up |
| Notify known owner by certified mail | Person taking up | Within 5 days of taking up |
| Send written notice to ODA (or hand to brand inspector) | Person taking up | Within 5 days of giving owner notice |
| ODA investigates ownership | Oregon Department of Agriculture | Within 20 days of receiving notice |
| ODA notifies owner if identified | Oregon Department of Agriculture | Within 20-day investigation window |
Care and Cost Responsibilities While Holding an Estray in Oregon
Once you take up an estray, you take on a caretaker role. The animal must be fed, watered, and sheltered until it is either reclaimed by its owner or transferred to the ODA. Oregon law recognizes this burden and allows you to recover those costs — but only if you follow the procedural rules correctly.
The recoverable costs under ORS 607.304(2) include the reasonable expenses of taking up the animal, giving notice, and keeping the animal during the holding period. These are the costs the owner must pay before reclaiming the animal, and they are also the costs paid from sale proceeds if the animal goes to public sale.
There is a timing trap worth knowing. If a person gives the notice required by ORS 607.313(1) but fails to do so within the time allowed, the person may recover only those costs verified by the department of taking up the animal, of giving notice, and of keeping the animal that were incurred within five days immediately preceding the giving of the notice. In other words, if you wait too long to notify the ODA, you forfeit cost recovery for the period before your late notice — so filing promptly is not just a procedural formality, it directly affects your finances.
Key Insight: Keep dated receipts for all feed, hay, veterinary care, and any fencing or containment costs you incur while holding an estray. The ODA will need to verify these costs, and undocumented expenses may not be recoverable.
If you are a livestock owner yourself and want to understand how Oregon’s transportation and movement rules interact with estray situations — for example, when moving a found animal to a secure location — review the livestock transportation laws in Oregon for the applicable permit and inspection requirements.
It is also worth noting what you cannot do during the holding period. You cannot use the animal for work, breed it, or otherwise exploit it for your own benefit. The estray process treats the animal as property held in trust pending resolution of ownership — your role is custodian, not owner.
How Livestock Owners Can Reclaim an Estray in Oregon
If your cattle or horses have gone missing in Oregon, acting quickly is in your financial interest. The longer the animal remains in someone else’s care, the more costs accrue — and you will be responsible for paying all of them before you can get your animal back.
If the owner of an estray animal appears and claims the animal prior to sale, the owner shall pay to the State Department of Agriculture all costs described in ORS 607.337(1) and shall pay to the person taking up the animal all accrued costs described in ORS 607.304(2). Upon such payment, the department shall release the animal to the owner or the agent of the owner.
The costs you owe fall into two buckets. The first goes to the ODA — these are the department’s administrative and handling costs for managing the estray case. The second goes directly to the person who took up your animal — their documented expenses for containment, feed, and care during the holding period. Both must be paid before the animal is released.
What if you dispute the amount the person taking up your animal is claiming? If the owner is unable to agree with the person taking up the animal as to the amount of the costs payable, the owner and the person shall proceed with arbitration of the disagreement. This arbitration provision prevents either side from holding the process hostage over a billing dispute, and it also means you cannot simply refuse to pay and demand the animal back without consequence.
The window for reclaiming your animal runs from the date of taking up through the sale date. The time of sale may not be less than 30 days and not more than 45 days after the date of taking up the animal. That gives you a defined window of at least a month to come forward, but the clock starts on the day the person took up your animal — not the day you learn about it. Registering your brands with the ODA and keeping your contact information current in state records is the most reliable way to receive timely notice if your livestock go missing.
For livestock owners who also deal with animals on the road or near public highways, Oregon’s roadkill laws in Oregon address what happens when livestock are struck by vehicles — a separate but related legal area that can arise when animals escape and reach public roads.
What Happens When an Estray Goes Unclaimed in Oregon
When no owner comes forward within the statutory window, the Oregon Department of Agriculture moves the animal to public sale. This is the end of the road for the estray process, and it transfers legal title to whoever purchases the animal at the sale.
The State Department of Agriculture shall cause an estray animal to be sold at public sale if the department is unable to determine in a timely manner the owner of the animal, or if the estray animal of a known owner is delivered to the department and sale is required because of the owner’s failure to appear and claim the animal.
Before any sale takes place, the ODA must give public notice. The department must cause a notice of the public sale to be given by posting a written or printed notice of the time and place of sale, a description of the animal, and that such sale shall take place if the animal is not claimed by the owner prior to the sale. The posting shall be in two public places of the county where the animal was taken up for not less than 48 hours prior to the date of sale.
The sale proceeds are distributed in a specific order of priority. The ODA’s administrative costs are paid first under ORS 607.337. The person who took up the animal is then reimbursed for their verified holding costs under ORS 607.338. Any remaining proceeds after those payments are handled according to the department’s procedures.
Once a sale takes place, ORS 607.336 governs the title of the purchaser at sale, giving the buyer clean legal title to the animal. This protects purchasers who buy in good faith at an ODA-administered public sale from later ownership claims.
Important Note: If you believe your animal was sold in error — for example, because you never received notice — ORS 607.339 addresses the liability of the department. Consult an Oregon attorney with agricultural law experience if you believe the statutory process was not properly followed before your animal was sold.
The public sale mechanism reflects a broader principle in Oregon’s estray law: the system is designed to be time-bounded and orderly. Animals cannot be held indefinitely in legal limbo. The 30-to-45-day window, the notice requirements, the ODA investigation, and the public sale process all work together to give owners a fair opportunity to reclaim their property while protecting the person who took up the animal and ensuring the animal does not suffer from prolonged uncertainty about its care.
If you own or manage livestock in Oregon, staying current on the full range of animal-related laws in the state helps you avoid costly surprises.
