Sir Dingles is missing!

I knew it was just a matter of time. The Call of the Wild was too much for my future tub liner/pet. Sir Dingles is missing! I leave the front door ajar every night, so he can go out and stalk, but this morning, instead of finding him reclining on his Le Corbusier Chaise, gnawing on a femur, I found nothing. Some scat here, a chewed up old ladies' orthopedic slip-on there... But no Sir Dingles. So, I'm making posters which I need my readers to distribute. Spread the word near and far, for I must see my Sir Dingles again! I had the tub all prepped for his pelt.
