Tabaxi are creatures who need less rest than other mortals.

Long rest needs 5 instead of 8 hours.

Tabaxi are known to suddenly be able to move at incredible speed, covering incredible distances in a blink of an eye.

You have a cat's keen senses, especially in the dark. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern colour in darkness, only shades of grey.

Tabaxi’s cat-like reflexes and agility are matched by few in Allurian

When making a dexterity related skill check you gain a +2 to that roll

Tabaxi have razor sharp claws which can match steel blades.

You have a climbing speed of 20 feet. You can unarmed do extra one damage and they do piercing instead of bludgeoning damage. 

Tabaxi are able to dart across the harshest of terrain with ease.

When traversing through non-magical difficult terrain, you can subtract ten feet of movement instead of reducing it by half. 

The lightweight of Tibaxi’s combined with their agility make them extremely hard to detect.

You gain advantage in all stealth checks.

Tabaxi have a keen sense of danger that is ill-understood by most, able to sense danger before it comes.

Once after a long rest, roll 6D6, on a 6+, you gain a sixth sense die. You can use that die to add 1D6 to any perception check, reflex saving throw or choose to subtract 1D6 from an enemy attack roll.
