[en] A structure for housing small mammals and small fish comprises one or more cages 10 for housing the small mammals and a tank 12 for housing the small fish, the tank including a tunnel 14 connected to a cage 10. Advantageously, the tank and tunnel are transparent which allows the pet owner and anyone else viewing the structure to view the mammals as they move from their cage to the tunnel. The structure preferably further comprises a base 16 for locating the tank and each cage. In a preferred embodiment, the structure comprises two cages, and the tunnel is connected to both cages. In this case, the tunnel passes through the centre of the tank and includes an enlarged section 18. The structure provides an interesting environment for keeping pet fish and small mammals such as hamsters.
