Mine are 3.6 lb and a 6.5 lbs of uncomfortableness that I can't fall asleep unless they are in the uncomfortable positions!!
Rosie scratches at the bed until I pick her up. Mind you, if I have a treat in my hand while laying in the bed she never has a problem climbing onto the bed using the steps placed beside the bed specifically for that purpose!! And then she has to fall asleep on my pillow right next to my head preferably on my face so it is hard to breath. Ruby scratches on the covers until I lift them up so she can crawl underneath. But that is not enough...she then scratches at my legs until I lift my knees and keep them up so she can scootch right next to my thighs/derrier under my raised knees. If she decides she is too warm she again scratches for me to lift the covers and then she needs to lay between my thighs or knees...
I should preface that my preferred sleeping position is curled up on my side which is not conducive to their sleeping positions. Uncomfortable for me but I wouldn't have it any other way!!!
