Behnam Mohammadi

It is a certificate that allows you to work with animals (and there are two different types, FELASA B and FELASA C). To acquire that you need to take a course. The registration fee and duration of the course may vary from one country to another country. In Germany, the FELSA B course is about 1000 Euro and takes about 3 days.
