 Similar examples of temporary coincidence can arise when objects gain or lose parts. Tibbles the cat is made of the usual catty parts, including a tail, and a tail-complement, i.e., all of Tibbles except for her tail. A tail-complement is a slightly strange object, but it’s rather like a torso, i.e., all of an animal except for its limbs and head. Tibbles has a whimsical owner, who names the tail-complement ‘Tib’. One eventful day, Tibbles loses her tail in an accident: she shrinks to become exactly the same size and shape as Tib. On the one hand it seems daft to count Tibbles and Tib as two different objects after the accident. But on the other hand they do seem different: Tibbles has been a cat for years, unlike Tib, and Tibbles is her owner’s favourite animal, while perhaps we cannot say this of Tib. These differences suggest that, after the accident, Tibbles and Tib are two different things occupying the same place at the same time.
