There’s been a surge of AI content like this lately. The raccoon/opposum/whatever animal getting startled by a holloween decoration was the one circling around last week. Now it’s this one.

Yeah, at some point the cat is both behind and in front of the pillow.

I'm not going to make any comment on if it's AI or not, but the 'weird flash at the end' is the visualize touch option for Samsung phones with at least half of the pixels fried off. If it's real, it could be that whoever was cropping this video left the touch at the end, and if it's AI it somehow got in its head that the end of videos often have this pop up.
