Also, if they're repeatedly getting up on areas you don't want them to, it probably means they don't have enough perches they are allowed up on in the area. Cat's naturally like to perch to observe their territory. If they're getting up on the kitchen table for instance, put perches or even a whole cat tree near it. Eventually they'll learn to use the new perch instead of the table, sometimes even naturally if the perch is higher and more comfortable.
