I looked into it a little using TinEye and the image predates generative AI images of this quality. I actually think it’s a photoshopped normal cat; possibly as part of that weird trend of making some small detail of a normal photo look freakish.

That looks like it might be a baby stinkpot (S. Odoratus)! They’re a kind of mud turtle, so marshes are their happy place.
Baby snappers have long tails, but it could also be one of those that lost its tail.
