We have a 10 year old Tabby who has started to jump up to the kitchen sink and get various small items like the stopper, disposal cover, small plastic lids and then jump back down. She then carries the item around the house meowing very loudly, its almost a howl. She does not bring it to us except occasionally. She does it both when we are here or away. Sometimes we come home to 2-3 items carried throughout the house. Any idea what she is thinking or up to?? Thanks
