I had one cat that was a therapy cat. He always slept just to the left side of my pillow purring madly all night long. The day I came home from the hospital after my appendix operation he moved to my right side and slept as close to the incision as he could get. I had to put a pillow over me side so he wouldn't step on me there. But from that time on he always slept on my side. I learned to keep a pillow with me when I slept for him to sleep on. He was a 12 pound cat so was pretty heavy. He would sleep with his body on the pillow and his head on my body. I sleep on my side so if I rolled over in the night the pillow and the cat rolled over to the other side. When I was depressed or upset he would come and just sit near me like a statue watching over me. I called him my Buddha cat
He did try to climb into my lap while I was sitting on the toilet but I am not that tolerant.
But he would sit outside the door and meow loudly if he got locked out of the bedroom especially while my husband and I were having sex. I swear he would have dug his way under or through the door if he could have.
