A gerbil palace
And our gerbils receive a palace:

This is actually not a very good home for gerbils. They are very territorial and known for fighting to the death. When fighting breaks out, we naturally want to give them more space to get away from each other. However, more space allows them to set up territories and suddenly fighting is amplified.

Ours haven't shown any propensity toward aggression, yet. The boys are still a bit too young for that. But we are preparing the homes for their separation and thought it would be fun to link them all together for the moment.

The children are completely fascinated as they watch them dart through the tunnels, dig in the dirt and discover the treasures we've hidden for them. It is almost as if they were in amongst them, playing, wrestling and settling down for the occasional nap.
