Hello!
Is Taco in an area that is quiet and undisturbed? (no tv/lights/noise?) She may be reacting to hearing you up and about. Every once in a while I will hear my guys moving around and one, Sydney always has a midnight snack!
They are in thier own room, covered and quiet. My little Emma decided she wanted a sleep cage at the age of 7.
She became very restless and would not calm down. Her sleep cage is next to her day cage. Each night when it's time to go to bed, she will climb into the smaller cage and settle down.
I would "listen" to her tonight and see if she settles. Perhaps she was intune with something that we are not aware of (Like the northeast's Earthquake last week) and things will return to normal.
If not, then try to notice ANYTHING differnt in the room or the environment. Make sure she has peace and quiet and if that doesn't work, consider a sleep cage in a quiet area so she is able to get the rest she needs.
Good Luck!
