That must be hard having to wait! Shame you can't get her now, but then the 25th May will be an exciting day
I posted on the let's see your cages thread already - but having another thought about the access to the two left shelves. Just a suggestion, but I think it might work better if:
1) You put the smaller bendy ladder next to the left bars, going from the lower shelf to the upper one.
2) You move the bendy stick tunnel further back to the edge of the cage, giving access up to the lower shelf but underneath the other ladder and the upper shelf. Plus it would be easier to climb up without the other ladder attached.
3) That means if your hammy jumps off the top shelf she can't land on the bendy bridge and will just land on soft substrate.
Just a thought
Kind of climbing up the shelves in shorter stages. They can fall off things sometimes.
