First off, here's some background information. The bacteria that do most of the work in a compost pile are aerobic bacteria, but the bacteria that thrive on meat scraps are anaerobic. The difference between these two types of bacteria is how they generate energy. Aerobic bacteria require oxygen to digest waste. Their bodies oxidize carbon compounds and generate heat as a byproduct of their growth and reproduction. There are many different types of aerobic bacteria, and when they work together they can eat nearly anything. Aerobic microbes also require nitrogen to produce proteins so they can grow and reproduce. Beneficial bacteria obtain energy from organic material, and they produce heat as a byproduct. This heat accelerates the activity of other bacteria in a reinforcing cycle. On the other hand, anaerobic bacteria grow quickly in areas without fresh air. They break down proteins to generate energy, and do not produce much heat.

They also produce some very smelly byproducts that can make a compost pile stink like rotten eggs or sour milk. These smells often attract scavengers. Compost that contains meat can attract mice, skunks, buzzards, and even bears. Biting flies will also lay their eggs in this type of compost, which leads to more flies and more bites. All of these scavengers take nutrients from the compost pile that would be better used as fertilizer. It's still possible to compost animal products, but this requires a specially designed composter.
