Cougar scat looks similar to a large dog’s droppings but with key differences: it’s segmented, typically 1 to 1.5 inches in diameter, and packed with visible hair and bone fragments from prey. Recognizing it can help you identify cougar activity in your area, whether you’re hiking, tracking wildlife, or trying to figure out what animal has been passing through your property.
Size, Shape, and Segmentation
Cougar droppings are deposited in segments, each roughly 1 to 1.5 inches across. A full deposit is usually 5 to 9 inches long, though it may appear as several connected or separated segments rather than one continuous piece. The ends of each segment tend to be blunt or rounded rather than tapered to a point, which is one of the more reliable ways to distinguish cougar scat from that of canines like coyotes or wolves.
The overall volume is comparable to what you’d see from a large-breed dog. If you’ve ever walked past a Great Dane’s mess on a trail and wondered, you’re in the right ballpark. But the segmented, cord-like structure sets it apart from the more uniform shape of dog feces.
Color and How It Changes With Age
Fresh cougar scat is dark brown to nearly black, with a moist, slightly glossy surface. The color depends heavily on what the cougar recently ate. A meal of deer produces darker, denser scat, while smaller prey can lighten the color slightly.
As the scat ages and dries out, it fades to a grayish or chalky white. Older deposits often look bleached and crumbly, especially in dry climates where sun exposure speeds the process. In wet environments, scat breaks down faster and may become difficult to identify within a few weeks. If you find a deposit that’s still dark and moist, the cougar was likely in the area within the past day or two.
What’s Inside: Hair, Bone, and Other Clues
The most distinctive feature of cougar scat is its contents. Cougars are obligate carnivores, meaning their diet is almost entirely meat. Their droppings reflect this. You’ll commonly see coarse animal hair woven throughout the scat, often visible on the surface without breaking it apart. White or pale bone fragments are also typical, sometimes appearing as small chips or shards mixed into the mass.
Research on mountain lion digestion shows that cougars swallow significant amounts of hair and bone, particularly from prey like deer. Bones that pass through a cougar’s digestive system show heavy surface erosion but often retain enough shape to be identifiable. In practice, this means the bone pieces in scat tend to look rounded and pitted rather than sharp-edged. You might also spot fragments of teeth from smaller prey animals.
This carnivorous content is a major identifier. Coyote scat, by comparison, frequently contains seeds, berries, insect parts, and plant material alongside hair. If the scat is full of nothing but hair and bone, you’re almost certainly looking at a feline predator.
How It Differs From Bobcat and Coyote Scat
The two species most commonly confused with cougar based on scat are bobcats and coyotes. Here’s how to tell them apart:
- Bobcat scat looks structurally similar to cougar scat since both are felines. It’s segmented, contains hair and bone, and has blunt ends. The difference is size. Bobcat droppings are noticeably smaller, typically under an inch in diameter. If the segments are clearly over an inch across, you’re likely looking at cougar.
- Coyote scat is often similar in overall size to cougar scat but tends to be more tapered at one or both ends, sometimes twisting to a point. It also frequently contains non-meat items: berry seeds, grass, insect exoskeletons, and fur from small rodents. The texture is often looser and less uniform than the dense, compacted segments of cougar scat.
Wolf scat can also overlap in size, but wolves are absent from most of the cougar’s range in the lower 48 states. Where both species are present, wolf scat tends to be slightly larger in diameter and may contain larger bone fragments from elk or moose.
Where Cougars Leave Scat
Cougars often deposit scat along travel routes: ridgelines, game trails, old logging roads, and the edges of clearings. They tend to use prominent spots that function as territorial markers. Look near trail junctions, along creek banks, and at the base of rock outcroppings.
One distinctive cougar behavior is the “scrape.” A cougar will sometimes rake its hind feet across the ground, creating a small mound of dirt or leaf litter, then deposit scat on or near the pile. These scrape mounds are a strong indicator of cougar presence even if the scat has since decomposed. The scrape marks themselves look like parallel grooves about 6 to 8 inches long in the soil. Not every cougar deposit includes a scrape, but when you see one, it’s a reliable sign.
Smell and Freshness
Fresh cougar scat has a strong, musky odor that’s distinctly feline. If you’ve ever been around a house cat’s litter box, the smell is in the same family but more intense and gamey. The scent fades as the scat dries, and older deposits have little to no smell. Wildlife detection dogs are trained to distinguish cougar scat from that of other wild cats by scent alone, which gives you a sense of how specific the odor profile is, even among related species.
Health Risks From Handling Cougar Scat
Like all wild cat feces, cougar scat can carry Toxoplasma gondii, the single-celled parasite that causes toxoplasmosis. You can pick up the parasite through direct contact with contaminated feces or soil. The CDC recommends wearing gloves if you need to handle anything that may have contacted cat feces and washing your hands thoroughly with soap and water afterward.
For most healthy adults, toxoplasmosis causes mild or no symptoms. It poses a more serious risk to pregnant people and anyone with a weakened immune system. If you’re examining scat for identification purposes, there’s no need to touch it. A stick can flip it over to reveal contents, and a photo from a few inches away captures enough detail for identification. Keep dogs away from it as well, since they’ll instinctively investigate and may roll in or eat wild scat.
