We grow tomatoes in the garden. Something is eating them! It must be an animal. How do I know?
I know because animals leave clues behind them. You see, different animals eat things in different ways. These clues can help us find out what kind of animal is eating the tomatoes.
Maybe it is a squirrel. Squirrels use their claws to pull tomatoes off the plant. They hold the tomatoes and nibble them. They take small bites.
Maybe it is a bird. Birds use their beaks to peck holes in tomatoes. They leave the tomatoes on the plant.
Maybe it is a deer. Deer eat the tomatoes, the leaves, and the branches of tomato plants. They can stand above the plant and eat the whole thing.
Is it a dog or a cat? Probably not. Dogs and cats do not usually eat tomatoes.
