Hi, we have just bought the exact same cage so we can bring our boys in.
Just set it up and it's great. At the moment though, they are not too impressed! think it **** feels very exposed to them as they keep darting from one side to the other at a zillion miles an hour! I've covered the top now so they feel like they have a roof. Hoping that'll help them to settle. They are yet to explore upstairs.
I felt that the ramps were a bit steep so I extended them and covered with vet bedding. They are sniffing round them as I type but so far not brave enough.
Would love to see yours when it's all set up.
