It’s a daily struggle between my 13 yr old son leaving his clothes on the floor and my cat dragging them to her litterbox. I don’t know why she does it. I have also found tennis balls and toilet paper in there too lol . I change her litter quite often too.
the old clothes in the litterbox is a favourite in our house too
It's because they see their litterbox as a place that belongs to them and no one else, so if there's something they want to keep for themselves, they will drag it to their litterbox. Some cats will use their food bowl instead.
