Gray tabby with white paws, blue collar, missing

I lost my gray tabby cat yesterday around 7pm. She's about 9 pounds, gray with white paws and a white bib, and she wears a blue collar with a small bell and a round ID tag. She has a slight limp in her right hind leg and a tiny triangular scar on her left ear, and she darted out the door when I was bringing groceries near the Victoria Gardens mall in Rancho Cucamonga. I'm really worried - she's friendly but skittish with strangers, and she means the world to my family; if you see her, please text me, and I'd be grateful to get her back home.
