I stand over Clover and scritch her belly from both sides at once.  She
immediately does a somersoult!
 
I'm currently looking for a housemate.  I was interviewing one person, and
had already introduced her to the ferrets, when Princess came in and
climbed onto the beanbag.  I said she's about to rollover, and she did!
We both laughed.  Princess loves the bean bag, and will usually rollover,
stand, rollover again, then run away.
 
Sandra, Clover and Princess
