Cats get a Xmas Tree, this is a special tree just for the cats. You may enjoy it too because it is a pretty Xmas tree that has on off particle lights and 6 different versions of tree textures. The cats can play with the tree like many cats do and if they happen to knock a ornament from the tree they get an extra ball toy for a few minutes before it magically hangs it self back on the tree.
You can find the trees located at either of the main sim store sims. The cat version that this works with is the 1.3.3. If your cats don’t see the tree make sure the version is current.
