My domestic short-hair cat, Backyard Blackie Boo Boo Boo (short name Blackie), is missing. I last saw him at about 4:30 PM on Monday, December 11, 2017, on the patio in the back of my home at 5045 Royal Lane, at the NW corner of Royal Lane and Inwood Road. He is completely black with no distinguishing markings except for his right ear being cropped to indicate that he was neutered at the Preston Royal Animal Clinic. He is current on all vaccinations (last given on November 8, 2017), also provided by the Preston Royal Animal Clinic. He has no collar but he has a microchip. His microchip number is 981020007264226. He is about 5 1/2 years old. He was in good health and when I last saw him at about 4:30 PM on Monday, December 11, 2017. On November 8, 2017, Preston Royal Animal Clinic professionals weighed him. He weighed 13 pounds at that time. Please contact me if you see my cat and/or have any information about him. Thank you very much. Hopefully he did not venture beyond Russwood Acres, but, just in case, I chose the default Surrounding Neighborhood option.
