Cat and Mouse

Your Tabaxi ancestry brings out your hunting sense more keenly than in most.

You have advantage on all Wisdom (Perception) checks that rely on hearing or smell. 

If you use your Feline Agility trait and move at least 20ft, and hit a melee attack, your target must make a Strength saving throw or be knocked prone. The DC is 8+your proficiency bonus+your Strength or Dexterity modifier (whichever you used to make the attack). The target automatically passes the saving throw if it is Huge or larger.
