You should love wildlife and have an affinity for anatomy, sculpture, drawing, photography, chemistry, sewing, or hunting. You must be professional and have good manual dexterity, be self-directed and creative. A veterinary background would be a natural foundation for a career in taxidermy. Studio arts may be another way to get started.
Formal education comes in the form of workshops, seminars, apprenticeships, and classes. There are plenty of trade schools and, in many cases you'll need permits and certifications. There are industry certifications from the National Taxidermy Association.
