Heated kitty bed?

I was wondering if anyone here has seen any products available anywhere 
else similar to the one below?

Two things I like about this product:
1. Activates only when kitty gets on it
2. Uses only 4W of power!

Bad? Shipping at this site is like $10.  I'd like to buy it anywhere else.

kitty’s comfort. Energy-efficient heater only uses 4W and is removable. UL 
listed for indoor use. USA.

[Ed. I wonder if this thing is guaranteed not to be a fire hazard?]
