Anna Soffer woke up one day to a lion in her living room.

At least that's how Rooster, who is actually a house cat, appeared that bleary-eyed morning — a towering feline frozen in mid-yawn.

"It kind of looked like he was a lion about to pounce," Soffer tells The Dodo. "So I Photoshopped him with a bunch of lions."

At 26 pounds, Rooster is certainly the king of this Los Angeles household. Technically, Rooster belongs to Soffer's roommate, Darcy Ripley. But in Soffer's imagination, Rooster is all hers.

"I started Photoshopping him in different situations and people seemed to think it's really funny," she says.

In real life, no one's quite sure how Rooster took on such epic proportions. According to legend, or at least fading memory, he was once actually a tiny kitten. Ripley spotted him in an online ad. If no one took Rooster home, the kitten would be dropped off at the pound.

So Rooster found an XXL-sized place in their lives.

But a few years ago, Rooster ran away from home. Maybe the cat just wanted to stretch his legs a bit and see the world. In any case, he was soon scratching at the door of his home again — and desperately relieved to be home.

"When he came back, he was really skinny and sickly," Soffer explains. "After that, he just never stopped eating."

That enormous sense of relief may have contributed to Rooster's ever-expanding girth. He gorged on his grateful family's generosity.

And he's a perfectly healthy cat.

"We've taken him to the vet," Soffer says. "We've had his blood work done. He's obviously on a diet. He just won't lose any weight."

And Rooster has been inspiring awe — and awwws — ever since.

"I wonder if people who work at the Grand Canyon wake up every morning and are amazed by the Grand Canyon," Soffer says. "Every morning, I wake up and I'm amazed at how giant this cat is."Anna Soffer
