Sometimes art

Instead of weapons, you fight with your claws. You jump, you twist, and your meows and hisses have different abilities. But if you make TOO much noise, your human/s hush you, and you can’t continue with your assault until they’ve left you be. 

There are various spirits and some are helpful. Ghost mice give you life, ghost crickets give you information, and a former Guardian cat is your guide. You have to succeed where your predecessor failed- finding the source of the haunting and getting rid of it.
