Omaha, Nebraska - An adorable opossum in Nebraska ate an entire Costco chocolate cake – with near disastrous results.

Volunteers from the Nebraska Wildlife Rehab Inc. rescue center shared the story on Facebook.

The opossum was taken in shortly before Valentine's Day. The animal had previously broken into the home of real estate agent Kim Doggett and eaten an entire chocolate mousse cake, CNN reported.

The astonished homeowner described how she discovered brown paw prints on the porch. When she went inside, she found the opossum lying on her new beige sofa, panting. Meanwhile, all that was left of the cake were crumbs.

Together with her son Hayden, Doggett tried to scare the wild animal away, to no avail.

Then mother and son remembered that chocolate is deadly for many animals and contacted the American Humane Society. The little opossum was picked up and taken to the rescue center.

"It appears that she was lucky to have been caught red-handed, because it allowed her to come to our hospital and get diagnosed with what can become a fatal condition in wildlife," Laura Stastny, executive director of Nebraska Wildlife Rehab, told CNN.

While chocolate is completely safe for humans (in normal doses), many domestic and wild animals lack an enzyme that breaks down theobromine, a substance contained in cocoa.

Dogs, cats, and horses, in particular, fall victim to chocolate poisoning.

The cheeky possum survived its mishap and is on the road to recovery. He should be released back into the wild as soon as possible, according to rescuers.

In the meantime, the little culprit has gone viral, earning the nickname "Cake Bandit."

To mark the "sweetest scandal of the week," animal lovers are selling "Wanted! Cake Bandit" t-shirts to support efforts to save native wildlife.

Opossums are the only marsupials in North America. The gentle omnivores are considered "living fossils." When they feel threatened, the animals often play dead.
