I have one that for the last few months she headbutts me
She will go to the furthest part of my bed and come "crash" to my nose. I think it is a strange way to wake me up for a potty break but it is kind of cute
I am glad I sleep really lite because now when she leaves my side I can sit up, but she still gets me every now and then.
Some of the things they do are so cute, I can never have a bad day for very long because they always find a way to change it
I have another that has to do her "army crawl" under the covers before she will get out of bed in the morn.
