What do you get when you combine a ‘the most mom text possible’ and a cat named Finn the Stormtrooper? The mew-est viral Internet craze.

Toronto freelance writer Danielle Matheson never expected to go viral, but since tweeting a photo of her mom’s latest experiment with the family cats at their Brantford home on Monday, her tweet has been seen by more than 11 million people.

“It's totally wild. I really don't think anyone would be prepared for that.” Matheson said. “It was the most Mom text possible, but I didn't think it would turn into this.”

Matheson’s tweet captioned “nobody has had a more productive day than my mother” included three photos. First was a screenshot of a text sent by her mom reading “so Pintrest says if you put a square on the floor a cat will get in it.” The next picture shows Finn the cat inspecting a square made out of pink duct tape. The last photo shows Finn successfully sitting inside of the square.

Since the tweet was posted on Monday, it has been retweeted over 90,000 times and liked over 200,000 times. And Matheson has been inundated with photos as members of the Twitterverse try to get their own cats in squares.

“Really surprised this just happened! He went straight for it as soon as he saw it!” Twitter user Lynn Ash shared with a photo of her cat sitting inside a square.

“I love the responses. People are so excited to try it. Strangers are having cute conversations in the replies and sharing pictures of their pets that look like other people's pets,” Matheson said.

Matheson’s family has three tuxedo cats — and even though Finn pawed his way to viral fame, the two other cats, Digit and Combo, also took turns sitting inside the pink square.

“I thought it was an adorable text and accidentally ended up tricking the Internet into sending me cute animal pictures all day,” she said.

“Cats are super weird and adamant on doing their own thing. It took two days for their other cats to get in the square. Some are instantaneous. My favourite cats are the ones who just start defiantly ripping the tape up.”
