I leave the cage open when I am home, which is a long time throughout the day. I am always around to supervise any interactions they have with saoirse, although mostly she ignores them which is awesome.
They haven't slept outside of their cage until today, though. They usually go back inside their open cage to sleep.
Here they have a spot behind the couch only accessible via tube, so inaccessible for the dog. This is one of a few ferret specific places they can hide and feel safe.
I'm glad they're finally sleeping here as it means they feel more comfortable and are settling in well!
