What's the most unbearable pet you've ever had?

I once had a teasing meow named Han Duoduo. When eating, I have to put it in a higher place. Sometimes I feed it in my hand. I don't eat it on the floor. I have to sleep together, or I will sleep on your pillow in the middle of the night. I can open and close the door by myself, like to play with water, and make trouble every time I take a shower. I brought it here when I moved last year, but I didn't get it back when I went out in a different place. Now I miss it very much. Maybe it has gone.
