Identify Animal Scat and Droppings
Scat tells you what wildlife is sharing your space — sometimes the only sign before you see the animal. Our AI scat identifier names the most likely animal from shape, size, content, and location. Most relevant for homeowners noticing droppings in the attic, garage, or yard, and hikers checking for predator presence on a trail.

Animal scat is one of the most reliable signs of which wildlife shares your yard or trail. Identification reads the size, shape, and contents of the droppings, plus where they were left. A photo with a scale reference helps name the animal, and flags scat like raccoon's that can carry a real health hazard.
Below are the kinds of scat people most often need to identify around homes and on hikes. Scan yours with something for scale, and handle droppings only with care.
Common types of animal scat
A quick reference to the ones people ask about most. Not sure which you have? Snap a photo above and let the AI name it.
Deer pellets
Small, smooth, oval pellets dropped in clusters. One of the most common signs of deer in an area.
Rabbit pellets
Round, dry, pea-sized balls, often scattered in large numbers near feeding spots.
Dog and coyote scat
Tubular and tapered, often with hair or bones in wild canine scat. Coyote scat is usually left on trails.
Raccoon scat
Dark, tubular, often in a communal latrine. Can carry roundworm, so treat it as a hazard.
Rodent droppings
Tiny dark grains scattered along walls and in cabinets, a key sign of a mouse or rat problem indoors.
Bird droppings
White-and-dark splashes rather than formed pellets, since birds pass waste and urine together.
Why identifying animal scat matters
Raccoon scat carries roundworm eggs that survive years in soil — knowing it is raccoon and not dog changes the cleanup. Bear scat on a trail tells you what berries are ripe and whether to make more noise. Rodent droppings in the attic tell you if you have rats, mice, or squirrels, and each takes a different exclusion approach.
What helps identify animal scat
Size and shape
Tubular and tapered: most carnivores. Tubular and segmented: raccoon. Pellets: deer, rabbit, rodents. Plops: bear, large herbivores. Length and diameter narrow which animal of that shape family.
Content visible
Bones, fur, feathers: predator (coyote, fox, raccoon, bobcat). Berries and plant fiber: bear, fox, raccoon in season. Plant matter only and pelletized: deer, rabbit, rodent. Visible content is one of the strongest clues.
Location
Attic: rodents, squirrels, raccoons. Garage: mice, rats. Trail center: coyote, fox (territorial marking). Yard edge near food: raccoon, opossum. Location filters heavily before any other detail.
Freshness
Glossy, dark, moist: hours old, animal is still nearby. Dull, lighter, dry: days old. Freshness decides urgency — fresh predator scat on a trail is a signal to make noise; old scat is informational only.
Handle with care: scat that carries disease
Droppings are an identification clue, but some are a genuine health hazard. Raccoon scat can contain roundworm eggs, and dried rodent droppings can carry hantavirus that becomes dangerous when disturbed. Never handle scat bare-handed or sweep it dry. If you must clean it, wear gloves and a mask, dampen it first, and disinfect the area. Identify from a photo rather than up close.
Photo tips for the best identification
- 1Photograph from straight above with a ruler or coin for scale.
- 2Capture both an overview shot and a close-up showing texture and content.
- 3Note the location (attic, yard, trail, near water).
- 4Do not handle scat with bare hands — raccoon, fox, and rodent droppings can carry parasites. Mask and gloves for any cleanup.
Frequently asked questions
Is this from a dog or a coyote?
Coyote scat is usually rope-like with tapered ends and contains hair, bone fragments, or berry seeds. Dog scat is rounder, softer, and contains processed kibble (no hair or bone). Coyotes also drop scat in the middle of trails as territory markers; dogs scatter it.
How do I tell rat from mouse droppings in my attic?
Mouse droppings are rice-grain sized (3-6 mm), pointed at both ends. Rat droppings are larger (12-18 mm), blunter, with the Norway rat tending toward more rounded ends and the roof rat more spindle-shaped. Quantity also splits — mice produce 50-75 droppings per day, rats around 40 larger ones.
Is raccoon scat dangerous?
Yes, more than most people realize. Raccoon roundworm (Baylisascaris) eggs are extremely resilient and can cause serious neurological disease if accidentally ingested (children, pets). Treat any raccoon latrine as a hazard: wear N95 and gloves, bag it, and decontaminate the surface with boiling water or a flame.
