Sybil and Benny in Hibernation.
Benny is the one with the harness.
They don't really sleep all day and all night. They will get up.
However, they do not prefer to go outside.

Their Loft is really higher than what it looks, they just filled it with straw.
When they do sleep, they bury themselves in the straw..
