Two headed animals are pretty rare, the only two headed animals (apart from humans) that I have heard of are reptiles or amphibians.

Healthy two headed snakes can sell for around 10-20 thousand

That's a pretty large group of animals. As it is, two headed animals can be found in a lot of different animals, it is rare though, and usually fatal. Extra limbs is also a thing, for more info, look into the hox gene and how its expression drives development.
