Shares of Chewy popped in the premarket trading Monday after a Securities and Exchange Commission filing showed meme stock trader “Roaring Kitty” took a stake in the pet food e-commerce retailer.

The filing showed Keith Gill bought just over 9 million shares — amounting to a 6.6% stake in the company. That makes him the third-biggest Chewy shareholder, according to FactSet. Based on Friday’s close, that stake is valued at more than $245 million.

The stock was up more than 20% before the bell.

The SEC filing also included a section that read: “Check the appropriate box to designate whether you are a cat.” There was an “x” next to a response that read: “I am not a cat.”

Chewy shares took a wild ride last week after Gill posted a picture on social media platform X of a cartoon dog. Shares were up as much as 34% on Thursday but ended the day down slightly.

 CNBC emailed Chewy PR seeking comment on the new shareholder.
