I have noticed Mr Lewis’s tail is constantly moving, in fact even when he’s asleep it twitches while he’s dreaming. My Mother says Mr Lewis’s tail tells him to be naugty, which is why he is so loving one minute and the Devil’s own sidekick the next. I expect the diet we have him on at the moment is making him particularly crabby.  Despite his occasinal boughts of bad temper, Mr Lewis is one of the best family cats we have been privileged to live with. Although I may revise my opinion of him if he dives under my duvet in the small hours and bites my buttock again!
