Attitude:
Sabertooths often live in communities, in "families" one may say. These families are all centered around the leading male, and usually contain several females that are certainly the most dangerous and skilled when it comes to hunting - their main occupation when they don’t have babies to care for.

Weapons :
Do we need to make it clear? Their teeth are fearful and the power of their jaws is formidable; they can crush anything.
Don’t disregard their claws though. Since it is very fast, the sabertooth jumps on its prey and takes all the time it wants to pull him/her to pieces.
