If she is young, this is all play to her. Knocking things over is sooo much fun and it gets your attention! I'm afraid it's all or nothing for the counters; if you don't mind her up there, then expect the behaviour or keep your counters clear - I've had to do this myself, although which of us is easier to train is a toss-up
.
If you only have the one cat, play with her often, wear her out. Leave safe playthings around, crunchy balls, catnip mice, etc. Buy a laser pointer and run her ragged from the comfort of your chair.
I buy rough mats from the dollar store (not like a real doormat, more like indoor/outdoor carpeting). My cats love the horizontal claw treatment as much as the vertical.
Good luck. Cats CAN learn but it takes persistence and (sometimes) a loud voice.
