A four-eared cat named Batman has found a new home within hours of being put up for adoption by a Pennsylvania animal shelter.

Batman’s extra ears are the product of a recessive gene mutation needed from both parents, according to the Western Pennsylvania Humane Society in Pittsburgh, where the unusual feline was surrendered last month.

“Just when you think you’ve seen it all, a four-eared cat comes in the door!” the Humane Society’s managing director said in a Facebook post.

The cat stayed for a month so that he could be treated for a respiratory infection, a common ailment amongst shelter animals.

A mother and her young daughter adopted Batman on Tuesday, only hours after the shelter posted video of the unusual animal.

“It was fitting because the little girl liked superheroes,” communications manager Caitlin Lasky told ABC News.

Black cats like Batman have a reputation for being the least likely to be adopted, due in part to an inability to capture them in photographs.

However, a 2014 article published to the ASPCA blog, while more black cats are entering shelters, they are being adopted at higher rates than cats of different colours.

And with shelters filled to the brim with cats during the summer season, the Humane Society said that Batman can become a hero in his own right – by getting more people to the shelter to adopt.
