Adults average 75 to 250 pounds, but some get twice as large. They can stand up to 3 feet tall and reach 5 feet long, and males (boars) are larger than females (sows).

  • Russian (Eurasian) boar type: long, straight, narrow snout; dark-colored or camouflage coat; light-tipped bristles
Where in Louisiana
Feral hogs are found in all 64 parishes in Louisiana, and Louisiana’s feral hog population is currently estimated at 700,000. Louisiana Department of Wildlife and Fisheries

Domestic cat Not stated

TWRA says the domestic cat is smaller, usually has a longer tail and is not spotted with black. NCWRC says a bobcat is about twice as large, and South Carolina DNR says its legs are longer. Tracks of young bobcats are easily confused with house cat tracks (Missouri).

Official advice from Louisiana Department of Wildlife and Fisheries:

What official sources say

Are there black bears in Louisiana?

Yes. The Louisiana Black Bear (Ursus americanus luteolus) is on LDWF's Common Mammals poster and is a state SGCN (S3). Louisiana Department of Wildlife and Fisheries

“Ursus americanus luteolus Louisiana Black Bear G5T2 S3”

Are there armadillos in Louisiana?

Yes. Nine-banded Armadillo is on LDWF's Common Mammals poster; LDWF classes armadillos as outlaw quadrupeds. Louisiana Department of Wildlife and Fisheries

“Outlaw quadrupeds include the feral hog, an invasive species which has caused severe crop and land damage throughout the state, as well coyotes and armadillos.”

About this list

The species list comes from Common Mammals of Louisiana (LDWF poster, 2018) + 2025 SWAP Table 4.13 (Mammal SGCN) (Louisiana Department of Wildlife and Fisheries, poster 2018; SWAP 2025). 28 more entries come from other official sources named on each card.

Venom labels come only from official sources and link to them; "Not stated" never means harmless. How labels work.

"Nonnative" and "Invasive" follow the wording of the source list. See invasive species in Louisiana.
