Is Nyan Cat an NFT?

Could you please clarify for me if Nyan Cat, the popular internet meme featuring a cat with a rainbow trail and a pop tart body, is indeed considered a Non-Fungible Token (NFT)? I'm curious to know if this beloved internet icon has been transformed into a digital asset that can be bought, sold, or traded on blockchain platforms, given the recent surge in popularity of NFTs. Thank you for your insight.
