Water squirting doesn't work for Litha. He just shrugs it off. (I think he's a bit stupid. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />) One that's always worked for me is a sharp tap on the nose. It has to be done just after they've done what ever they've done wrong or they'll get confused.

Gwen was beng very troublesome for some time (weeks). She was demanding everything and hissed and growled at me whenever I provided. I finally cracked it (for which I am ashamed <img src="/ubbthreads/images/graemlins/shame.gif" alt="" />) and put her in the cat-carrier in the closet for 20 minutes. It worked, though. She still demanded what she wanted, but she was at least civil about it. She became a lot more friendly too, strangely.
