We took in 3 'male' Gerbils from a friend. They also turned into 10 Gerbils! We had them in an old fish tank half full of damp compost. Was great watching them dig tunnels etc.

I did make a mistake of attaching the large water bottle to the side of the tank with tape though. One of them chewed through it and it fell on him. We found a slightly U-shaped, very dead Gerbil the next morning.
