I'm with Gill.
You can't discipline or train a cat, they have no concept whatsoever of rules... or if they do they don't think they apply to them. And they are right.
Cats do what they like, how they like, when they like, where they like and in whichever order they want, full stop.
Trying to make them do stuff or stop them doing stuff will only result in stress, frustration, upset and misery for you, the dedicated slave, and the general amusement and hilarity
of the cat.
Don't give them the satisfaction of giving you that blank, hurt "What me? I don't understand" look.... don't expect manners or good behaviour from them and then
when they do behave or do what you want them to, it will be a pleasant surprise.
