Still missing young female short-haired tabby cat (Centennial)

My black & tan tabby went missing this summer and I still haven't found her yet. She has a distinctive white stripe on her nose, and all four paws are white. Her fur is short and smooth and stripey. She is spayed and microchipped. No collar. Please contact me if you may have seen her in the past few months, even if you don't have her in your possession. If the tip leads me to the correct cat, I will give a reward for the info. Offering a much larger reward for her safe return. Many cats have similar markings, so if you catch one that looks like this, it's a good idea to have a vet scan the microchip (for free.)
