When Laura and Kana go shopping, the Ham-Hams go along, but soon find danger in the shopping district. A large, mean cat lives in an alley in the district, and after Bijou goes down the alley, she doesn't return! The Ham-Hams go looking for her and find that Bijou has fainted among the alley-cat's kittens after being frightened by the protective mother cat. The Ham-Hams attempt a dramatic rescue, but Hamtaro and Boss are chased, and the others get trapped under a bucket. Unexpectedly, Laura and Kana show up and begin fawning over the baby kittens. The proud mother cat turns her attention away from the hamsters, and at last the Ham-Hams are able to make their escape.
