Gray tabby cat with blue collar and bell

I found a gray tabby cat this afternoon around 4:15pm behind the Walmart on 16th Street in Yuma. It has a bright blue collar with a tiny silver bell and a small crescent-shaped scar on the right ear. The cat is about medium-sized, very friendly, and purrs as soon as I pet it. It also has one white paw that stands out when it stretches. It seems well cared for, and it followed me for a bit when I called. If this is yours, I can meet you at the Walmart parking lot or take it to the Yuma Humane Society to scan for a microchip.
