deliberately knock things down. Others do it accidentally while climbing and leaping around.
Ember is the only cat that I've had who deliberately knocks things to the floor. She has broken drinking glasses, stoneware cups and bowls, and a glass salt shaker. None of them were valuable pieces. She also used to knock down containers of soft margarine which caused the lid to pop off, leaving her free to snack on the margarine. She has spilled tea and water by knocking over cups and water bottles. If I put a vase of flowers on a table in the living room, they go to the floor, too, but for reasons known only to her, she does not knock over flowers in the dining table.
She now leaves cups, glasses, and margarine containers alone and instead focuses on books and papers on my desk or the hand sanitizer bottle on the counter just inside the door. She no longer knocks things down randomly, without purpose. She does it 1) when she wants attention while I am watching a movie or reading a book, and 2) when it's close to feeding time and she wants to remind me of it.
I did have one cat several years ago who was fixated on vases of flowers on the dining table. He did not knock them to the floor, just knocked them over, spilling water and flower petals all over. He never touched anything else.
