Pet Death...Is this Creepy?

I've found a place on the net that cremates pets. Do you think this is creepy? The reason I ask is that I have a cat, I rent, and I have no place to bury the cat when he dies; and unfortunately I don't think he will make another winter. I've also found a another site that will make jewelry from your pets ashes...now that one I find disturbing....but to each his own! I'm seriously considering cremation but only because I can't even contemplate burying my cat in a place that I know I won't be living in for a long time. Besides, my cat thinks he's my man anyway!!! More on that later..

Here are the sites, Please let me know what you think!
