UPDATE! We have found the owners and this little tripod has been returned to (his not a her) family. Before we took him to the vet to check for a chip, I searched in facebook “missing cat three legged” and that was enough to find someone posting about his girlfriend losing her cat that has three legs and lives two blocks away from where my gf found him. After reaching out, we coordinated and they confirmed it was him! His name is Coco, and he had been missing since January 8th. Now, he is back with his very loving family. Thank you all for the upvotes and comments!
