Yes, anything goes in my books. I will pick and choose what I want to eat based on my personal preference.
Even human meat would be ok in my books, as long as the person being eaten has agreed to it and was not killed, specifically for the purpose of being eaten. (Suicide and murder are not legal where I live).
Being a domesticated species means nothing in the context of food chain and nourishment. Neither does how smart another species can be.
Give or take a few exceptions such as near extinction, to make sure the species is not fully eradicated. But once it's numbers go back up to self sustainable levels, go ahead and throw it on the grill!
