I'm sure my late cat, Oliver, named after Oliver Twist, knew exactly what I was saying to him. He would always talk back to me when I talked to him. I sure wish I knew more cat talk so I could have understood him better.
My other cat, Sasha, named that because she was so sassy as a kitten, is an entirely different story!!!
I tried and tried to keep her off the counters, etc. when she was little, to no avail. I'd use a spray bottle to try and teach her to stay off of things and all she would do was play with the spray!! Now that she is 10 and much fatter, she can't jump up that far anymore so it's not as much of a problem..
Cats, ya gotta love em.
