If your fur get's wet you'll be forced to make all ability checks and saving throws with disadvantage until you dry off.

You can speak Meowing and Common, but prefer to not speak Common to humanoids

You lack opposable thumbs and walk on all fours, you can only wield weapons that have the light property and you must wield it in your mouth

You do not need materials to cast spells, unless those materials have a specific cost.

You got Murder Mittens and they hurt! They are Light and Finesse (You can use EITHER your DEXterity or your STRength) for your attack modifier

During a short rest you may spend your rest napping and gain one hit dice (which can be rolled during this rest) or one spell slot

You always land on your feet! Your beans are springy and grant you Advantage on Acrobatics and Stealth checks, also DEX saving Throws, and you take half as much falling damage

Poor kitties, gotta die 10 times to die properly. Hope they aren't traumatized
