Your Dexterity score increases by 2, and your Wisdom score increases by 1.

Tabaxi have lifespans equivalent to humans.

Tabaxi tend toward chaotic alignments, as they let impulse and fancy guide their decisions. They are rarely evil, with most of them driven by curiosity rather than greed or other dark impulses.

Tabaxi are taller on average than humans and relatively slender. Your size is Medium.

Your base walking speed is 30 feet.

Because of your claws, you have a climbing speed of 20 feet. In addition, your claws are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike. Once you have grappled an opponent, even if the grapple is mutual, you can Rake kick with both feet to deal 2d6 + your Strength modifier in slashing damage, this attack is made with advantage and can be performed only once per turn, you must not be wearing boots to perform this attack.

You can make a standing vertical jump of half your movement distance.  A running jump only requires that you move 5 feet, your running jump can cover up to half your movement in distance or any less distance, and can be repeated in the same turn as long as you have movement remaining.  Both of these cost the same amount of movement as the distance covered.

For every 10 feet that you fall you may attempt a Dexterity (acrobatics) check to reorient yourself, if necessary.

While falling facing down unarmored and carrying less than your own weight in equipment you are able spread yourself out, increasing wind resistance, stopping the accumulation of falling damage dice while in this position.  While in this position you can also maneuver 5 feet perpendicular to your fall direction for every 10 feet you fall.

When landing from a fall while facing down you take half of the remaining falling damage (rounded down).

While you are conscious and facing down, if you are knocked down, you are not considered to be Prone.  From the Prone position (on your back) you only need to roll over, using 5 feet of movement, to be considered no longer Prone.  This movement is enough to qualify you to perform a running jump.

Your upbringing was animalistic and did not teach you any languages. You can however understand animals in a limited capacity as their forms of non verbal communication are more native to you than speech.

You can use speak with animals at will, for you this is an innate ability and not cast as a spell.  Also you do not need to speak to communicate with them, you may do so visually using facial expressions, gestures, and body language.
