Part 2: Dora's set up (single roborovski)
20 Gallon Long aquarium, Rubbermaid bin, Habitrail tubes connecting the two.
There's normally a Flying Saucer wheel in this bin, but I sold my 5" saucer and waiting for a 6.5" to arrive.
Without the bin on top:
Sand and digging area:
Nest/food/wheel area:
To get up, Dora uses the ramp or climbs up the rectangular block with holes and on top of her house (Trixie Jesper)
