The so-called subway kittens -- who caused train service to be briefly halted in Brooklyn earlier this year -- are now old enough to be adopted. But get in line: the duo already have a long list of suitors.

New York's Animal Care & Control, which is sheltering the cats, calls the pair "arguably the most famous kittens in New York City history" and describes them as "playful and sweet kittens, whose trouble-making days aren’t entirely behind them (though the trouble they’re up to now is on a much smaller scale than the kind that made headlines over the summer)."

Those headlines came in August, when the two kittens were seen on the tracks of the Church Avenue station. Service was suspended for two hours while a rescue effort was mounted. Eventually, the cats were corralled and fostered for several week in Brooklyn.

But reputation as escape artists be damned: as of Friday afternoon, a spokesman for New York's Animal Care & Control said nearly 40 people had inquired about the pair.

Those interested in adopting both Arthur and August—the AC&C says the pair must be adopted together—are encouraged to email adoption@nycacc.org. And if they're not available, the shelter says "there are currently many other kittens and older cats who need loving homes."
