One of the great things about Pierre, is that his feet are rubber and are meant for teething and general chewing delight. That being said, my son will chew/suck on any part of Pierre if he gets the chance. And when his hair is all crusty and matted from saliva, I just throw him in the washing machine and he comes out good as new! Fantastic!
Pierre is made by a French company called Noukie's (http://www.noukies.com/). He isn't one of their current toys, but they have a wonderful program that if something were to happen to Pierre, I could buy a new identical toy from them so my son's heart wouldn't be broken.
(Of course, when looking for Pierre on their website, I found out that he is, in fact, a cat. He looks like a bear to me, though, so we'll keep on referring to him as such.)
