The cushioned basket can be built in the Cat basket space of the Kitchen in a player-owned house. It requires 33 Construction to build and when built, it gives 58 experience. The player must have a hammer and a saw in their inventory to build it.
Cats/kittens/pet rocks belonging to anyone can rest on the blanket. When exiting house via portal, the kitten/cat sleeping on the basket will come to the player. To place the animal on the cat blanket, the player must pick up the animal and use it on the blanket. Pet rocks will remain in the basket even if the player leaves.
Cats must be picked up during building mode.
