My ferret, Abby has taught me that when she "sits-up" on her hind legs, it's
time for me to get up and give her a treat.  Sometimes she has to get my
attention first by tapping me on the leg.
 
She probably thinks I'm a little "slow" since, sometimes, she has to repeat
the command several times before I perform; and sometimes, when she wants to
show me off to her buddies, I won't do it at all.  Still, she seems to love
me, though, in spite of it.
