It’s from Nevermore Wildlife Rehabilitation - they take great photos of their rescues!

Dont use AI to judge whether something is AI. It doesnt work. Just use your eyes and you would notice its a completely normal photo that just had the saturation pumped up to a weird degree. AI is still nowhere near this level of quality. It doesnt do detailed hair and flowers like this. It also doesnt do irregularities like that single cut stalk.

This is not slop. This is an edited picture by a wildlife rescue.

Here is the video of the same opossum who has become sort of a mascot for them, crawling over the same flowers: https://www.facebook.com/share/r/1J2hbhpWyj/

I agree with the sentiment but not with using a probabilistic ai detector which routinely put out wrong results. I checked for ai watermarks at slopornot.ai and there don't seem to be any, giving the image just a 65% of being ai. Now I agree that the flowers look suspicious but it could still be an artificial flower bed with some oversaturation going on. Unless the source given by op has a history of posting slop, I am inclined to believe this might be real.
