I searched "stuffed" in my wardrobe looking for stuffed animal items. The item showed up as a wearable option. Of course when I clicked it, it just showed a broken item icon in the top left corner of the avatar since it's not wearable. This item only showed up in the owned items section.

I can't remember if I had one or not to be honest, when I search my account it shows up as having been fed to a pet before. I also sometimes just use quickstock to send every item in my inventory to the wardrobe after questing, including the non wearables just to be faster. So not sure if that had any impact or anything...
