Sophie slept in her bed for well over a year, maybe 2, but I can't remember. I did not trust her as she took a long time to potty train and be trusted, and therefore, her kennel was safer for us. However, when she finally was trustworthy, my husband felt sorry for her, and he let her sleep with us. She has ever since, and she is 6 now. Poor kitty, however, got the boot from the bed. We have bed wars if we don't close our bedroom door. Kitty out, Sophie in.
