I need to write a paper summarizing a current animal article on animal nutrition. The article can be no older than 3 months and I need to have 4 articles on the same subject to write from. So I'm trying to think of a subject that I will be able to find 4 articles on. Such as a controversial topic on a certain animal that I can find lots of info on. The sample article was done on dogs and feedings raw food diets. Does anyone know any animal nutrition controversial topics? It would help a lot. Thank you!
