Space is a really tough environment, but astronauts who live on the ISS are used to the unusual conditions. But what can we say about animals that they bring on board? Well, they show some quite interesting behaviour!

Scientists suggest that the animals were just stressed — or maybe they were attempting to make up for the lack of physical activity.
