Pull up cat
Seeing the humans hanging in that manner is a very common sight. Many folks do pull-ups like this to build-up their upper body and to strengthen their arms. But cats don’t have this type of fitness purpose in their mind, so when we look at this picture it is very odd to see a kitty hanging from a door frame, as if she is doing some pull-up.
We clearly are clueless how the kitty would have managed such a position in the first place, but it sure looks like a hanging in the air above the dog. It looks like it surely doesn’t have any idea how to get back down, so hopefully, its owner comes to the rescue.
