this guy that sells this is at the Stormspire, his title is "Exotic Pet Vendor" and on my server, this costs 36g, he also sells other pets, such as cockroaches, rabbits, and snakes, but they cost more than what u would spend if u actually found the vendor that specifically sells these things.  Such as the rabbit hes selling, it costs 2g from him, but the rabbit vendor is only 30s. :)
