Cats have lifespans equivalent to the average cat.

Cats are tiny,

Your base walking speed is 20 feet.

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 color in darkness, only shades of gray.

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.

Additionally, due to your tiny size you may not wield weapons with the Heavy tag. 

You have advantage on deception checks to pass yourself off as an ordinary cat. 

You can speak, read, and write Common and one other language of your choice.
