Sometimes when my cat Oscar is feeling particularly excited and bitey and will not chill out, especially around my sister (she's pregnant) I will put him in timeout. I don't know if it works well in the long run but I have had success with it, I will set a timer for 3 minutes or so and put a clothes' basket over him, like he is in kitty jail. I don't keep him in jail for longer than 3 minutes and when I release him "on parole" he is back to his best behavior .
