A friend says two of his kittens often move the couch and move carpets around the house.
I have three cats (more precisely, a cat and two cats, one of which is only two months old) of medium size. And when these mini-elephants start the morning five-hour (in the sense, at 5 in the morning, not the length of 5 hours) rache (not raje) and ololonabigation... You wake up and look at the results: the carpet in the large room is almost a roll, the chair, usually standing at the computer table, lies (!) In the other corner, the paths in the hallway are on the wall, on the floor of a piece of advertising leaflet from the table at the mirror... The truth is that the couch is not moving yet, but who knows what will happen when it grows small.
