“Fisher cat” is another name for the fisher (Pekania pennanti), a wild member of the weasel family—not a domestic cat. Whether fishers are legally protected depends on where they live and which law applies: the Southern Sierra Nevada population in California is federally endangered, while a separate Northern California–Southern Oregon population received a federal finding that listing was not warranted in 2025. Neither decision answers every state or provincial wildlife-law question.
Are fisher cats protected?
There is no single federal Endangered Species Act status that applies uniformly to every fisher across its North American range. Federal decisions are population-specific, and federal listing is only one kind of protection. State or provincial endangered-species laws, trapping seasons, possession rules, and general wildlife regulations can differ. For a local answer, check the current rules of the wildlife agency responsible for the place where the animal is found.
- Southern Sierra Nevada, California: federally endangered under the Endangered Species Act.
- Northern California–Southern Oregon: the U.S. Fish and Wildlife Service found in 2025 that federal listing was not warranted for this distinct population segment.
- Other locations: these two federal decisions do not establish the legal status or rules for every fisher population or jurisdiction.
A “not warranted” finding means the agency did not find federal listing warranted for that population segment; it is not a declaration that fishers are unprotected under state or other law.
What is the current federal status?
| Population or action | Federal status or decision | Date and scope |
|---|---|---|
| Southern Sierra Nevada distinct population segment (DPS) | Endangered under the Endangered Species Act | The U.S. Fish and Wildlife Service published its final rule on May 15, 2020; it took effect June 15, 2020. Applies to this DPS, not all fishers. FWS species page and 2020 final rule. |
| Northern California–Southern Oregon (NCSO) DPS | 12-month finding that listing was not warranted | The FWS species-page information lists the finding on August 25, 2025. It concerns this DPS and is not a ruling on every fisher population or state law. FWS species page. |
| West Coast DPS proposal | Revised proposal to list as threatened, with a proposed section 4(d) rule | The 2019 publication is a proposal, not by itself a final current status determination. 2019 proposed rule. |
“DPS” means distinct population segment: a defined population treated separately for a federal status decision. The distinction matters because a final endangered listing, a not-warranted finding, and a proposal are different kinds of agency action. The 2019 proposal should not be presented as though it were a final listing.

Where does the Southern Sierra Nevada fisher live?
The range described by FWS for the Southern Sierra Nevada DPS extends from the Tuolumne River in Yosemite National Park south to the Greenhorn Mountains in Sequoia National Forest. FWS reports sightings in Mariposa, Madera, Fresno, Tulare, and Kern counties. This is the range of that California population—not the full North American range of fishers. FWS fisher profile.
What is a fisher, and how does it live?
Despite the name “fisher cat,” a fisher is a mustelid, in the same family as weasels, mink, martens, and otters. FWS describes it as a brown-to-black animal with a broad head, pointed snout, bushy tail, small ears, and white patches on the chest; males are larger than females. Fishers are opportunistic hunters whose main foods include squirrels, mice, and birds, and the agency also notes research documenting fungi in their diet. FWS gives a life span of about 10 years. FWS fisher profile.
What habitat do fishers need?
Fishers use forest habitat with substantial overhead cover and varied structure. FWS says they use tree cavities for dens and select denning and resting sites in forests with high canopy cover, snags, and downed wood. A USDA Forest Service ecological review also describes associations with high cover and structural complexity in large tracts of mature and old-growth forest. These are habitat associations, not a claim that every fisher occupies only one forest type. FWS fisher profile; USDA Forest Service ecological review.

The Forest Service review discusses fishers’ vulnerability to trapping and habitat-management considerations such as retaining den trees and coarse woody debris. That review provides ecological and management context; it is not the current source for the federal status decisions described above. FWS fisher profile; USDA Forest Service ecological review.

How to check the rules where you live
- Identify the state, province, or other jurisdiction where the fisher was seen or may be affected.
- Visit that jurisdiction’s official wildlife agency website and look for current species-status, trapping, possession, and wildlife-regulation information.
- Check whether the rule applies to the exact area and activity; federal ESA status, state listing, trapping rules, and general wildlife protections are separate questions.
- If the situation involves a captured, injured, or dead fisher, contact the relevant wildlife agency rather than assuming a rule based on another population’s status.
