Lost Tabby Cat with Pink Collar in West Covina

She is a 5-6 year old female (spayed) domestic short hair tabby cat. She has whit efur on her chest and belly as well as all four of her paws. She has a pink collar on with a bell and specific design on the collar. She usually roams around outside for a little bit since she's an indoor/outdoor cat, but this time she did not come back and it's very disheartening.
