HTML to "disguise" a link Options

[nikk]

Hey people!

I'm going to try to describe this the best way I can, so if it confuses you, I'm sorry. I'd really appreciate some help though.

I have a link that I want to send to my friend so they can go to a certain webite. I'd like to hide the website name.

In other words,
I'd like my friend to see a clickable link that said "cats".
And when they click it it will send them to http://www.dogs.com.
lol Sorry for the bad example.. but that's the only way I can describe it.
I would just like to know how I can make a clickable link that shows "cats" or whatever word I want it to show instead of them seeing the website. I understand that the website name will still appear in the address bar after they click it, unless that can be changed too. Please let me know how to do this.

Thanks
