Pretty much every accoutrement your dwarf hamsters or other small rodents could ever desire. Multiple cages is helpful for when your little friends after many months of happiness suddenly don't want to live together. (I know. It happens for humans, too.) We also found a spare cage useful for a place to put everybody when we were cleaning other cages. There are exercise wheels, water bottles, tunnels galore, nesting blobs, feedings dishes, a rolling ball explorer and even a car! This is definitely a package for your upscale and adventurous rodent friends. Only tiny sunglasses are missing.
