Sir Whines-A-Lot doesn’t let anything pass. Not any dollar notes, that is.

The lovable rescue kitty has been making quite a name for himself around the office of marketing firm GuRuStu, where he lives full time in downtown Tulsa, Oklahoma. During the day, he’s your typical feline employee, happy to offer a pleasant break for his colleagues, or hop atop their keyboard to send garbled emails on their behalf.

It’s in the evening time, however, that Sir Whines-A-Lot’s real work begins.

Upon returning to work one morning, GuRuStu founder Stuart McDaniel noticed some cash on the floor near the glass door where Sir Whines-A-Lot likes to sunbathe and people-watch.

How the money got there was a mystery — one that only grew deeper.

“We had no idea why it kept happening, but it did. Therefore, we chose to put a theory to the test, McDaniel told The Dodo. When we attempted to slide cash through the door’s opening, the cat sprang up and grabbed it.

It turned out that Sir Whines-a-lot, who has complete control over the facility at night, had been buying all that money himself. And the cash simply kept coming in.

McDaniel surmised that Sir Whines-A-Lot had been luring passersby to the glass while his coworkers weren’t around, prompting them to try to interact with him through the slot. In that scenario, a bill would make for a convenient cat toy.

“I’m guessing the first people didn’t intend to lose their dollar,” McDaniel said. “They probably put it in to mess with him, and he snatched it. When you hold money there, he’ll bat at it playfully at first, like, ‘Oh, that’s kinda fun.’ But then all of a sudden he’ll bite it and rip it from your hand. He does it so fast, you don’t even realize what’s happened.”

In time, the cat’s cash-grabbing tendencies became a local attraction. Before long, more and more people began toying with Sir Whines-A-Lot with moola — moola that they ultimately lose.

“It’s become a game. It costs you a dollar to play, ’cause the cat’s going to get your money,” McDaniel said.

This game is so easy for Sir Whines-A-Lot, it must feel to him a bit like stealing.

“He pats it when the money comes through. McDaniel said, “Like, ‘This is my money now. He’ll even roll around in the dough to wallow in it. In fact, he’ll roll around in it. It’s unlike anything I’ve ever seen.

Seeing as how their office pet was raking in the dough at night, McDaniel decided it should be put to some good use. He’s begun donating it to a charity helping the city’s homeless population. He figured Sir Whines-A-Lot would approve.

“He was homeless once, so it seems fitting,” McDaniel said.

So far, Sir Whines-A-Lot has raised over $100 — donated under his pseudonym: CASHnip Kitty.

McDaniels anticipates that when news spreads, more individuals will go out of their way to have Sir Whines-A-Lot steal their money. Additionally, the cat will gladly accept it from their hands:

He is obviously appreciating the attention, according to McDaniel. “We’ll continue letting him do it as long as he wants to,”

The fact that their chubby office cat has started working as a philanthropist on the side is something no one could have predicted, but it has only made them adore him more.

He was previously simply a silly cat, but now we appreciate him a lot more. He is contributing, according to McDaniel. I’d advise other companies to allow cats in the workplace, but I’ve never met a cat quite like him.
