Lost ginger tabby cat named Oliver with bright green eyes and pink bell collar missing from front yard in Southern WV.

My beloved cat, Oliver, has gone missing from our front yard in Southern WV. He's a ginger tabby with bright green eyes and a pink collar with a bell. He loves to explore but usually sticks close to home. I noticed he was gone yesterday afternoon, and I've been calling for him ever since. I'm really worried that he might have wandered off too far. If anyone has seen him, please let me know!
