Lola came home as a tiny puppy, having never slept in a bed before. The very first night, we put her in bed with us. She immediately started pecking my shoulder with her nose until I picked up the edge of the blanket for her. She ran straight under the covers & settled right in between my legs in a little ball like this was how she had been sleeping every night for her short life. This is where she always sleeps, under the covers. If it gets warm, she becomes "rigor mortis dog", locking her legs straight out, nails dug into my legs. It it gets hot, she wakes up, rushed to the top of the bed, sticks her head out of the covers, collapses & falls instantly back to sleep.
Callie came to me at a little over a year. She had slept in a crate at night at her breeder's house, so the first couple of nights were confusing to her. She finally got the idea of sleeping in the bed, and it took her another 2 confusing weeks before she figured out where Lola was dissappearing to. Once she figured out the under the blanket idea, she decided right by my chest was her spot, and has slept there ever since.
On cool nights, the cat will sleep next to my face on the pillow.
They have gotten used to me tossing & turning, and it doesn't seem to bother them in the slightest. I'm usually the least comfortable, but I wouldn't have it any other way.
