@nelejake I'm not completely sure about the cat scratcher, but the pet store needs to be downloaded from the Sims 3 Store. It should be in your purchase history.

I have the pet store, it used to have the palm tree cat scratcher, but it's disappeared

@nelejake If the scratcher originally came with the pet store and is now gone, then perhaps the pet store itself didn't install properly? I don't have the limited edition myself, so I can't check. But you can test: Pull your entire Sims 3 game folder out of Documents\Electronic Arts and onto your desktop, open the launcher to spawn a new game folder, and install the pet store. Start a new save and see whether the scratcher appears. If it does, then this is just an issue of the pet store not installing properly. If it doesn't, then the scratcher probably comes from somewhere else.
