This is some information on where 100% of our ferrets come from (so far). This is for information purpose and not a statement or a stand. However, I will share that less ferrets in pet stores would be wonderful and hopefully allow me to close the rescue, which should be the goal of all rescues to not be needed. Unlike dog and cat rescues, I would fully support someone who wants a young ferret to raise to not get from a pet store and instead look to ferret breeders. There are very few backyard breeders in the ferret world that will just give ferrets to whomever, breeders really screen their adopters, even more stricter than I do :-)
What's the recent buzz about Marshall Ferrets? For this post, let's first talk briefly about the company itself. See the comments section for links to other relevant posts- we will add more links as we get information compiled.
Marshall Farms Group, Ltd (MFG) is a major global producer of animals- pet ferrets, as well as laboratory ferrets & other laboratory animals such as beagles & pigs. It was founded by Gilman Marshall in 1939, in North Rose NY.
Today, MFG has evolved from a small hobby farm into an international corporation- the have two primary separate DBAs/operating branches:
• Marshall Pet Products: This is the commercial consumer division. It is not a standalone corporation; it functions as a consumer-facing product arm that sells ferret food, treats, toys, and small-animal accessories to major retail outlets.
• Marshall BioResources: This is the primary business division and registered DBA of the parent company used for B2B (business-to-business) operations. It handles the breeding, marketing, and global distribution of purpose-bred animals (beagles, golden retrievers, ferrets, pigs, etc) to laboratories and government agencies.
Where are they located? Marshalls has facilities of various types (not all have live animals) in the following locations:
• North Rose, NY
• Rose, NY
• Clyde, NY
• Waverly, NY
• Grimston, East Yorkshire, UK
• Lyon, France
• Gannat, France
• Mézilles, France
• Multiple locations in mainland China
While Marshall Farms Group, Ltd. holds the master USDA license for the entire facility in North Rose, NY, the company is understood to operate two strictly isolated genetic pipelines when it comes to ferret breeding.
The Marshall BioResources lab line prioritizes genetic uniformity and physical resilience for medical testing, resulting in a slightly hardier but potentially less docile animal. These animals are usually sold to research facilities intact, identified by metal ear tags or RFID chips.
Conversely, the Marshall Pet Products retail line was initially bred from a narrow genetic pool to favor an instantly docile, submissive temperament (for a ferret). This extreme, closed-line breeding is likely why retail Marshall ferrets tend to be prone to health issues with genetic risk factors like insulinoma and adrenal cancer, and even deafness. These ferrets are sold altered (desexed and "descented"), and are identified by two dots tattooed in one ear.
Although it has long been rumored that Marshall Farms has periodically introduced outside breeding stock to their lines (especially given the noticeable shift in physical structure since 2022) the USDA has MFG listed as a "closed colony"- meaning that no outside stock is brought in. Instead, they select for various traits from within their own closed lines. Although I was not yet able to locate USDA documentation for this post, USDA records should be able to definitively prove or disprove the rumors of imported stock.
MFG has long come under a great deal of scrutiny from the ferret community and animal activist community due to their questionable mass breeding practices and due to the fact that they produce and sell laboratory animals for animal testing.
The North Rose facility in New York is currently the site of continuous public protest, being led by (to the best of our knowledge) Beagle Lovers Rescue Inc & Direct Action Everywhere. Furever Ferrets Sanctuary, Inc. has been present at the protests, speaking out as one of the voices specifically for ferrets, along with other members of the ferret community, and New York Congressman Nick Langworthy has also made an appearance at the protests recently.
On a closing note for this post- Marshalls has played a large role in ferret culture in the United States for nine decades. Love them or hate them, and whatever their future (or lack there of) may be, Marshalls has left a significant mark here, and not necessarily a positive one. It's important to understand who they are as a company, and what they do beyond selling cute ferret kits in pet stores.
