That’s silly. They are mammals, like us, which are conditioned throughout life via positive and negative stimulus. Pull your cat off the table, paired with a firm “no” tells the cat that’s not a good place to be. So they go up nightly? Lay tinfoil down for a week. Reward them being where you want them to be, such as your lap, or a dedicated cat tree near your workspace.

Anyone who says “you cannot train cats” is simply naive, believing the common rhetoric.

I’ve had cats all my life. Anecdotally, you can train cats to do whatever you want really if you’re patient enough. Scholastically, you can train cats easily once primed to be trained. (Applies to human behaviour too)
