The Delta worker then makes an in-flight announcement to passengers that "there is a cat in the galley." <br /> <br />"Whoever's cat this is please come and ... wake them up if you see them with the cat carrier," she said. "I need them to come and get their pet." <br /> <br />One passenger tries to catch the cat, before another woman -- believed to be the animal's owner -- arrives and places the pet back inside its carrier. <br /> <br />Delta Air Lines allows cats to travel with their owners in the cabin on certain domestic and international routes for a one-off fee -- as long as the animal remains inside the carrier at all times, according to its website.
