You gain +2 to Dexterity and +1 to Charisma, but you're not quite as strong as a larger creature, with a -1 to Str.

Proficient in Acrobatics, Athletics, Perception, and Stealth

You gain darkvision to 60 feet.

You are proficient in all improvised weapons you are capable of wielding. That includes knocked over cups of water, trip attacks via spilled coin pouches, or push attacks via running around underfoot and making enemies stumble. If a cat can do it and be kind of annoying, you can do it for damage.

Your natural claw and bite attacks do 1d4+Str slashing damage.

You can communicate with any feline creature. Also dragons, but they tend to be super-patronizing and want to pet you.
