Pig slave
From Tardis Wiki, the free Doctor Who reference
The Pig slaves were the servents of the Cult of Skaro. They were Humans before the Cult converted them into beasts so that they could capture more Humans.
When the Pig slaves captured Humans, Dalek Caan did an intelegence scan on each of them. Humans of high intelegence were used for the "Final Experiment" and those of low intelegence were turned into the Pig slaves.
The slaves only lived for a few weeks. They were vicious fighters and were trained to slit a Human's throat with their bare teeth.
