For fun I draped an old cloth cover I have over the white tree and waited to see what Rhea would do. She started poking at the cover, but desisted in favor of the camera strap once I came up to take pictures.
Eventually she pulled it entirely down, so I draped it right over her. She seemed unaffected for the most part, and only made a move in order to bat at my fingers when I poked at her. Her head is in front.
The tower is also good for treat time!
Davout takes a little rest.
Rhea also invented a new game. She was trying to climb up the smooth outside of the tree by hooking her paws into the slots on the outside. She made it work once, but slipped and fell all the way down to the bottom another time.
To finish the theme, I brought out the undercover mouse toy for them both to play with in the evening.
