You smell an interesting smell coming from your father's cat tree. Cat beds baths and beyond doesn't exist because so much of the bath market is already taken care of naturally by the nature of the average cat. Much like cats of our universe, cats in yours lick themselves in order to clean. That just leaves beds and beyond. Cats have a large variety of sleeping vessels as they love to take naps and just sleep overall.
Cat beds can be CATegorized into 2 CATegories. The first CATegory is the low-to-ground CATegory. These are your normal beds, your cat murphy bed, your cat beds, your bassets, your futons, your couches, your cots, your sofas and couches, and even your floor. You are a subscriber of this doctrine, as you mostly sleep on your bed, which is just a mattress on the floor, so I suppose it counts as a futon, maybe. Whatever your bed counts as, you aren't one to sleep too far above the ground.
The other CATegory is the above-ground CATegory. This consists of any functioning sleeping vessel that can be wildly off the ground. You've got trees of various sizes, hammocks, flying mattresses, bunks, chain-raised beds, shelfers, magneto's, the ice box, and whatever else you can think of. The tree is basically the poster child of this CATegory. Trees come in a vast many sizes, ranging from the little ferns and saplings to the massive cat tree at the center of city hall that could potentially carry every Indigoan in it with extra for any humans who'd want to join in on the fluffiness. Your father's cat tree isn't very large, nor is it very small either. If it were a log scale between 0 being really small and 10 being the massive tree and 8.5 would be the mid-point, his tree would fit firmly at about 6. However, you aren't as much of a bed connoisseur as some cats that you know. Your grandmother was very proficient in bedding, and so her skills transferred to her son, but not so much to you.
