Overview and Meaning
Thrust is a form of threat behavior, which typically occurs first in the behavior chain.
The aggressor mouse will first threaten its target cagemate by thrusting its head and forebody towards its cagemate's head or body.
Agonistic interactions can occur in the context of territorial behavior, and/or dominance behavior. Territorial behavior and dominance behavior differ in both the context that they occur, the resources under competition, and the threat behavior that initiates the interaction.
