When are irse and salir used? What's the difference?

Thanks

Ricky

I was reading this sentence:

The cat walks out the window.

El gato sale a la calle por la ventana.

It seemed to me that this means more like: The cat go out through

the window.  So I put it into Google, which gave: 

Google: The cat goes outside through the window. Then tried another site:

Reverso: The cat walks out the window.and they translated it as: The cat walks out the window.

I would appreciate getting a clarification on this.  Thank you.

I think it would also be helpful to have examples with the conjugates that still have 'z', so that we know how it sounds and how to pronounce it correctly.
