You can now buy your very own Half-Life Headcrab for $25.

The Valve store states that these plush versions of "everybodys favorite Zombi’fier" are made to a quarter scale with approximately a 6" body, So they won’t fit over the head of a person but Valve have kindly dropped in the idea that it will fit over your pets head.
