This is a popular topic, and, here is what i wrote elsewhere, rita is one of my own breeding, from the devil spawn.
this may or may not help you.

well since rita has been here, she has jumped on my puter desk twice and the counter numerous times, she stole a thing of parmesan cheese, a bowl of formula that was meant for the pups, and a few other items including a spoon
when i catch her in the act, and i do i use the most deep and threatening voice, and i STARE HER DOWN FOR FIVE MINUTES
until she moves to a differrent spot and hangs her head.
she is now on day two, and so far since this morning i trust her totally.
i still watch her movements, but i know she will behave herself now
talking with your eyes goes a lonnnnnnng way
it worked for all my guys, but anticipating and catching them in the act is most important, i will say, WHAT ARE YOU DOING?
??
WHAT???
WHY???
and than the stare, i like it when they get up and move and i follow them with the stare and a few other words to go with, and pointing to the SOC
hahahahha
Scene of Crime LOL
