Chapter commentary:
Six months have passed.
The colony is now thriving and the burrow complex has been extended. Fermentation in the straw, triggered by the ammonia from the rats' urine, is even keeping them warm. As the colony now watches the approaching winter nights from the close comfort of a centrally heated accommodation, it is clear that our laboratory rats, initially naïve and hesitant when released, soon gelled into a structured and complex society. It did not take them long, when given the opportunity, to resolve successfully many challenges in ways similar to their wild cousins .

Clearly many wild instincts remain. Understanding how much of the wild rat remains hidden is relevant when housing them.

We may have taken the rat out of the wild but, clearly, we have not taken the wild out of the rat.
