Does this video show a cat being naughty in pushing a vase towards the edge of a table and then on noticing that she/he is being watched (filmed) changes her mind and pushes it back? Personally, I am not sure. I think she is simply pushing the vase around. That said cats do like to push things off tables as they seem to derive pleasure seeing objects fall and hit the ground. This may be a product of boredom. They are animating inanimate objects.
Cats know. If you communicate well and often with them, they know what you like and don’t like, but people often misjudge what their motives are. That’s where the confusion is.
