A feeding frenzy-like event, known as a killball, occurred naturally among slashrats when they encountered helpless prey or a fresh kill. These creatures emitted a mixture of sweat and pheromones, referred to as killscent, which served to notify other slashrats and had the ability to draw them in from considerable distances. The slashrat pack would encircle the prey, attacking it relentlessly and repeatedly until nothing but bones remained. While participating in a killball, slashrats disregarded all other potential targets, and one method of evading them was to divert their attention by disabling another creature. The Jedi Knight Corran Horn overcame the Yuuzhan Vong fighter Dranae Shai by mentally projecting killscent, which attracted slashrats and caused them to create a killball around the Yuuzhan Vong.
