Hello! I am from Spain and I have some doubts about the Oxbow pellets. I have seen that they have changed the formula of the Oxbow Essential and that now it is much worse. So I think the best I can give them is Oxbow, but seeing that they have changed the formula, I do not know what to give them now. I also want pellets with free GMO I have seen the ecological oxbow quite well and the natural science. Any recommendation?
