Mostly white with faint grey and bran tones. She’s 2 years old but only weighs about 7lbs. She is usually sweet and talkative but she’s never been outside before. She slipped out when we were bringing in groceries on the evening of 12/1. We scoured the neighborhood all night but assume she is either scared and hiding or someone picked her up assuming she’s a stray. She does not have a collar because she was always an indoor cat. We have 2 of her sibling cats and they are distraught as well. Please help!!
