Hi all! This is my first time to join this forum. Very excited. Anyways, my about-4year-old cat Bas has changed his usual sleeping spot last week. He use to sleep in our bedroom on top of a pillow just beside the radiator. It was his favorite spot for the longest time. However, from last week on, he's been sleeping in the next room on the carpet or downstairs on the sofa at night, instead of sleeping in our room. I am just wondering if cat gets tired of places and need to change once a while? or any other factor might have led to his "move"? I'm a bit worried, because he's my first cat. Thanks all!
