My old cat used to sleep at the end of my bed, always has done. However, I often kick out in my sleep which regularly resulted in my cat being shoved off the end of the bed and down between the wall at which point he would calmly make his way under the bed, hop back up and resume position without so much as a fuss. I tried keeping him out of my room for a while but he would sit and complain for hours until I let him back in. Still don’t understand that cat to this day lol
