Send textfield value to form in link

I am linking to The page with contact form from various other places throughout my website.
Can i add a textbox value to thoose links?

Example:
I am on the “LoLCats Page”
There is a link to the contact page that says “Ask us about LoLCats”
Can this link contain a value that fills a textfield? Like: Subject: LoLCats

Thank you
