I love it that you guys were able to catch them in the act. I get sleepy too!! Mimi is so funny......she tries to be "Miss Tough" with Butter and if he gets to close, she will hiss at him. But many times when she opens her mouth to fuss, it turns into a yawn, and she looks so embarassed, and Butter looks surprised! LOL!!! Poor old lady.....she needs more rest!!
