Along with the assortment of letters, bills and packages he typically drops off each day along his route, this particular postal worker delivers something far more warmly received.

He delivers joy to a handsome cat named Zeppelin.

About a year ago, Zeppelin came to discover a recurring event at home. Every morning, around the same time, a man dressed in blue would arrive outside the front door and slip mail through the mail slot — papery playthings Zeppelin grew fond of pawing at.

The mailman, realizing Zeppelin had made a game of his daily deliveries, began making that moment all the more fun for him. And from there, an adorable friendship blossomed.

“Zeppelin waits by the window, and when he sees the mailman coming down the street, he gets so excited and runs to the door!” Marisa Jaffe, Zeppelin’s owner, told The Dodo. “Highlight of his morning, for sure!”

Here’s video of Zeppelin and the mailman in action:

When the mailman arrives with his deliveries, artfully placed with Zeppelin in mind, the cat gets a big, happy boost.

“Zeppelin is as feisty and playful as he seems,” Jaffe said.

For the mailman, it’s no doubt an amusing highlight of his morning also — bringing a little joy to a random cat on his route. Seeing them enjoy their sweet routine, Jaffe can’t help but feel joy as well.

“I’m very grateful for their friendship,” Jaffe said. “And because of it, now I have a friendship with the mailman, too.”
