Hedgehogs are about 30 cm long and they weigh around one kilogram. They are small, but they are very cute.
There are sharp spikes all over their bodies that protect them from animals that want to eat them. These spikes are called quills. They don't have quills on their face and stomach. To protect their stomach and face, they roll into a ball. That means that predators can only bite their sharp quills.
Hedgehogs are carnivores. It means that they eat meat. They love to eat insects and small animals like snails, frogs, and even snakes.
Hedgehogs are nocturnal, so when people go to sleep, they wake up. They live everywhere in the Czech Republic. They usually live in forests and meadows, but they can be found in big cities, too.
