So I had a litter box in the basement of my sim's house. the cat would get all red and I would ask it what was wrong and it would say it needed a litter box. I would literally have to have my sim walk to the basement and call the cat to us the litter. Same with the food bowl. It would be full of fresh food and the cat would start to death unless I had a sim physically call it to eat or they were standing right next to it. I concluded they must have terrible autonomy programming with a very limited range.
That's a bug: Pets won't see items (food, litter boxes, scratching posts, toys) on another floor from where they are, even if they're old/big enough to use stairs. There are some mods that fix that, but it is definitely a bug in the game.
