You can compost meat, but the problem is that it will start to smell and attract flies and maggots (as well as neighbourhoods cats and dogs possibly). It also slows down the composting process. You can use a bokashi bin to preprocess all left-overs including meat, fish and dairy. It doesn't smell and after about 2 weeks the bin contents can be mixed with the compost heap. Tips on how to do this can be found here.
The downside is that you'll need the buy EM microorganisms regularly. Keep it enclosed to ensure critters can't access. Add low-nitrogen material to compensate (straw might be good), and accept that the bones are going to still be in large pieces when youa are done. Adding meat to the compost pile adds maintenance. It is not a hard rule to avoid.
