po kiego one tak intensywnie biegają?

@Thanos, chciałem pisać, że pewnie - tak jak choćby psy - lubią się wybiegać, ale skoro wrzuciłem, to sprawdziłem…

- Predators - This is the main reasons hamsters run, and it’s become an instinct. Hamsters are prey, so that means they have a very quick reflex of running away. They run, and they have to be fast, but they have to be agile first of all…
- Territory - Hamsters need to cover a lot of ground, in order to find all the food they need. They also need to find a mate, and they need to keep their territory in check. A wild dwarf hamster needs about 3.5 square km, which is about 1.35 square miles. A Syrian will need double that, so you can imagine there’s a lot of ground to cover for such a small creature…
- Energy level - Hamsters have an incredible amount of energy, and it needs to be expended. this is why hamsters can be found spending most of their time in the running wheel, when they’re not sleeping…
