Big cats have the following traits:
Pounce (Ex): If a big cat leaps upon a foe during the first round of combat, it can make a full attack even if it has already taken a move action.
Improved Grab (Ex): To use this ability, the big cat must hit with its bite attack. If it gets a hold, it can rake.
Rake (Ex): If a big cat successfully grabs its prey (see Improved Grab, above), it can make two rake attacks (+6 melee) with its hind legs as part of a full attack. Each successful rake attack deals 1d3+1 points of damage.
Scent (Ex): This ability allows the big cat to detect approaching enemies, sniff out hidden foes, and track by sense of smell.
Low-Light Vision (Ex): Big cats can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of poor illumination. They retain the ability to distinguish color and detail under these conditions.
Skill Bonuses: Big cats gain a +8 species bonus on Balance checks and a +4 species bonus on Hide, Jump, and Move Silently checks (for running jumps, the Jump bonus is +8).
Bonus Feats: Big cats gain the bonus feats Weapon Finesse (bite) and Weapon Finesse (claw).
