Where's Our Cat? is a magazine story.
When Thomas arrives at Wellsworth, the porter is looking worried. He explains that they have lost their cat and instructs Thomas to ask the other engines if they have seen her and gives Thomas a description.
As Thomas puffs around Sodor, he asks everyone if they have seen the cat. He asks Henry, Percy, and Harold who all promise to look out for her. James is not so keen to keep an eye-out; he has strange noises coming from his tender and needs to go for repairs. Gordon puffs alongside and peers into James' tender before bursting into laughter. Gordon calls the other engines over to look. Inside James' tender is the missing cat and six little kittens.
