I seem to remember reading about this in someone's blog a while back and wanting to post about it. Toasty Bear Products are:
Adorable cuddly plush animals filled with buckwheat or flax seed and our soothing blend of 9 herbs so they will heat in your microwave and bring you years of huggable pleasure.
I think this is supposed to be like the aromatherpy beanbag thing I have. You put it in the microwave to heat it, it gets all nice and warmm and is good for muscle aches or stress. I should actually use mine more often. But the idea of a stuffed animal as one sounds cool. Plus I kind of love the idea of shoving a stuffed animal into the microwave.
A friend of mine just now told me the bears are great. But that whenever they warm one up the cats all want to just sit on it.
Also available is the Toasty Manatee (just what I've always wanted).
