Jim Gardner challenge Question- stoping undesired pet behavior

To Jim Gardner of Lake Forest challenge. Question on how to stop undesired pet behavior.

It is a simple question, DR Jim Gardner. Many of them are reasons some people do not get cats.

How do you stop a cat from wanting to get on top of stuff like counters and tables?

How do you deter a cat from constantly getting into a open closet and sleeping / playing there, getting hairs on all the cloths hanging down?

How do you deter a cat from getting under the bed?

If a cat likes to get on top of my large speakers. when the cat jumps off he tends top know over the speaker. How to deter this behavior?

Feel free to not answer if the answer is too complex for you. Please avoid multi-page response's.

I totally can understand you can just ignore this, as it may be a little beyond your knowledge to solve.

Update- Sofar Mr Gardner has only responded ridiculing the post through his shell accounts. He only appears interested in complaining about problems, not solving them
