I held Henning down and brushed him all over, removing a small Henningsworth of fluff to prevent a recurrence. He likes having his beard groomed, but not his stomach or back legs, so he was not happy about this, but I gave him no option.
This sudden display of firmness seems to have brought dividends - this morning Henning was at full tilt chasing poor Footie up the stairs when I shouted 'HENNING! NO!' To my considerable surprise, Henning stopped and ran the other way, leaving Footie to make good his escape. Yay, I am Master of Cats. At least, momentarily...
Our cat hierarchy has switched again. The Bengals have been demoted. I think it now looks something like this:
though actually I'm not sure that works, because it doesn't take into account the 'pairs' system - Perl and Footie are a pair, despite being at the top and bottom of the tree respectively, and Henning and Kjetil are a pair. Also Kjetil will assert himself against Bengal lunacy if sufficiently provoked, though it doesnt' come naturally to him.
