Usually when I go to the cages in the morning to do a spot cleaning and clean out the potty areas, they all come running to play and see what treat I've brought. But sometimes they will ignore me, play hard to get and stay in their beds to see if I will come to them. Flower did that to me the other day. She stuck her head out of the cube to see what I was doing... and when I didn't give her a treat...
She laid back down inside the cube but kept peeking at me until she heard the crackle of the food bags and then she came running over. I found it quite amusing.
