Infamous Subway Kitten, Arthur, Missing From Brooklyn Home

NEW YORK (CBSNewYork) -- Arthur is on the loose again!

One of two stray kittens that brought subway trains to a screeching halt in Brooklyn two years ago has wandered off.

The gray and white cat has been missing from his Prospect Heights home since Nov. 20.

"We were out of town when it happened over Thanksgiving," Keith Lubeley, who adopted Arthur and his brother August, told 1010 WINS. "We heard through the house sitter that he'd escaped through an open window, which is terrible and unfortunately, possibly not terribly surprising when it comes to Arthur."

Lubeley said Arthur is the more skittish of the two cats.

Lubeley and his wife Katherine took in Arthur and August after the kittens wreaked havoc on the subway system on Aug. 29, 2013. Service was suspended for two hours on the B and Q lines in Brooklyn after transit workers cut power to the line as crews tried to catch the kittens.

Lubeley said August misses his brother.

"August has been spending a lot of time wandering around the apartment looking for him, meowing sort of forlornly, and it's very touching, but it's also very heartbreaking to see," Lubeley said. "We're trying to get them back together."

He is reaching out to the public to help find the cat.

"It's starting to seem possible that he's moved basically outside of our neighborhood into a wider expanse of Brooklyn," Lubeley said. "We're trying to spread the word to people that are not just in the Prospect Heights area, but around Brooklyn in general."

He asks anyone that may spot the cat to take a picture to confirm that it is Arthur.

Arthur is microchipped and neutered.
