In our room, we each have shelves next to our beds for our stuff.
My brother Hank filled his with random junk and old Star Wars Lego sets that he got from one of our 27-gallon buckets of Lego. He also likes to horde junk, like broken penguin ornaments, and use random things to make walls on his shelf.
My brother Ben filled his shelf with Warrior books, stuffed animals, and some 3D printed Warrior things. There is always toys and trash under his bed.
My shelf is our cat’s bed. His name is Angus. The basement of my shelf has all my stuff, the second floor is Angus’s scratching area and is kind of like a nightstand for me, and the third floor is where Angus mostly sleeps. The third floor is level with the windowsill, so he can stalk birds in the summer and sunbathe. Angus likes to sleep up there all day and usually only comes down once or twice a day.
