Few questions for yall:

What is the bar spacing on the Ferret Nation?
Is there a SOLID floor between the two levels? Because I want to keep the two girls on top and two boys on the bottom.

Where is the best place to get the CHEAPEST Ferret Nation?
Thanks!

1", I believe.

The floor is solid with a opening where the ramp is. The ramp can be brought up and hooked shut. To make double sure, you can contact Midwest and order a full floor for the second level (not sure on price).

Bar spacing is 1" by 5". there is a plastic tray for the second level, so no little rattie feet on the bars ;).
