Keith Gill, known as Roaring Kitty from the GameStop saga, now owns a 6.6% stake in Chewy, Inc., according to a recent SEC filing. The online pet food retailer could be Gill's next big play, as he holds sole voting and dispositive power over 9,001,000 shares. In a humorous twist, Gill confirmed in the filing that he is "not a cat." This move could draw investor attention to Chewy as it focuses on market expansion and improved product offerings. Gill's return to the market as Roaring Kitty has already caused volatility in crypto and stock markets.
