My furbabies sleep in my bed since they were little. I love to cuddle with them and they love to be under the covers. Espeacially now with this cold weather. If you don't mind sleeping with them in bed then you should let them and not worry. They won't get smothered. Believe me, they will move if they are uncomfortable. Sometimes I don't know how they can stay under the covers all night but it's been over 8 years and they are fine. So enjoy your cuddley one, I know I do!
