Im not sure if this is your cat or not or if yours is still missing? There is a small black and white cat around Domino's Pizza the last 2 or three times we closed, at 1-3 am, She is VERY friendly, very trusting she is mostly black, white front paws (I THINK) with a portion of her face white around the muzzle.
I felt very very bad for this cat and almost took the chance to bring her home tonight to give her a flea bath and some food. but im afraid of issues with my current cats. Im at work again tomorrow, and if this is your cat i literally saw her not 30 mins ago at the store as we closed. she was small though, and seemed younger than 9? although looks may be deceiving.
