This is cute, if a little strange. It's a mouse pad in the shape of a cat's head. You put your hand in the cat's mouth to reach the mouse. I did say it was strange.
I found one place that lists it for sale, but I didn't shop around so it may not be the best deal. The site is GeekStuff4U. I have never ordered from them, so if you're interested in buying one of these, please research it as you would any other product or company.
The mouse pad/heater is made by Thanko, the Japanese company that also brought us the Cat Face Allergy Mask.
All you need is a pair of cat ears to look like your favorite feline while breathing a little easier (theoretically). The mask also has a USB function - a built in fan. I'm not sure if it's to cool the air you're breathing in or to help blow away any allergens that might make it through the mask.
You can't say the company isn't imaginative!
