The Habitrail Ovo is a popular hamster enclosure system that is unique compared to others out there. The Habitrail Ovo allows for custom design of your own hamster cage.
However, due to the small size of some of the pods, we recommend that the Habitrail Ovo be used only for Dwarf Hamsters. We also recommend that owners purchase at least 2 cage sat a time for your dwarf hamsters as 1 is way too small.
It should also be noted that the Habitrail Ovo actually imitates the hamsters burrowing environment which makes it unique in its own way.
