Is Nyan Cat a NFT?

Could you please clarify for me if Nyan Cat, the popular internet meme featuring a flying cat with a rainbow trail, is indeed a Non-Fungible Token (NFT)? I'm curious to know if this beloved internet phenomenon has been tokenized and turned into a digital asset that can be bought, sold, or traded on blockchain platforms. If it is an NFT, I'd love to hear more about the details behind its creation and any notable transactions involving the token. Alternatively, if Nyan Cat isn't an NFT, I'm curious to know why it hasn't been converted into one given its popularity and cultural significance.
