Every year, pets are lost in cargo holds or baggage areas and are never found again. One pet, Jack the cat, was lost in New York City's JFK airport by American Airlines on August 25, 2011. American Airlines had mishandled Jack's carrier during the check-in process, which resulted in it breaking.
Jack wasn't found until 61 days later when he fell through a ceiling tile in the customs office, located in the same terminal where he had gotten lost. The kitty was severely malnourished and injured, and sadly had to be euthanized due to his condition. on November 6, 2011.
In an article by the New York Times, it was reported that Jack's skin was very thin due to the malnourishment and dehydration, which made him prone to organ dysfunction and severe infections. Before veterinarians recommended euthanasia as the best course for Jack, they had tried intravenous fluids, an operation, a feeding tube, and antibiotics.
Unfortunately, American Airlines was slow to provide a response and search for the kitty. It took the airline 60 hours before they called Ms. Pascoe back to give her an initial update on their rescue efforts. The airline only began to act more responsibly when the story hit the media.
What happened to Jack is absolutely heartbreaking. Please sign this petition so that we can prevent other pets traveling in the cargo section of airplanes from being lost.
