When animals leave their waste, like poop or pee, it's called scats.
Scats are usually found in nature and can tell us about the animals that made them.
Examples:
The scientist found some scats in the forest.
We saw deer scats on the trail.
The scats were near the river.
The bear scats were big and stinky.
The scats helped the scientist learn about the animals.
The scats were full of seeds and berries.
