Mitzi used to sleep with us.
She used to jump all over us at 2 and 4 and 5 in the morning to play!! The little fruit loop! So now she sleeps in her little house next to our bed. She sits with us until the light goes out, then she hops down and sleeps there, or on her big pillow on the floor. When she's older and a little less boisterous, she'll be back on the bed with us
It's helped a lot with her obedience too. I don't know why, but when she slept with us she was MUCH naughtier! Now, she listens ALOT more!
