Can't the future potential home foster her until it is determined whether she is lost or not? And, yes, you need a litterbox, with litter in it. You could probably get by with a temporary litter box using a large, sturdy box lid or an appropriately sized plastic storage bin or Rubbermaid dishpan. You don't need to buy a toy. How about shoelaces or a tinfoil ball? YYJ III will love the elegant simplicity of your creative solutions. Oh, also? You could buy a *small* bag of cat food. Or see if you can borrow some from a sympathetic neighbor.
