I think he means that ownership isnt a right exactly but a reality, I own this house because I will shoot anyone trying to invade it ect (i might be misunderstanding him though)
personally I think that a person "owning themselves" is just a simple fact that they can make their muscles move and their synapses fire and think their thoughts and no one can control them to the same level they can control themselves or make decisions for them, so obviously they own themselves, and its impossible to own another person unless you can control their thoughts
as far as animals go, I think as long as nothing else is controlling their thoughts they do in fact own themselves and killing them is an agression, but the nap isnt a hard and fast rule in an anarchy but more like a tendency that will enforce itself, you likely wont agress against anything if you fear the retaliation sufficiently, but you likely do not fear livestock, you might think twice about a move that could trigger consequences like trespassing, but if they are incapable of understanding the nap in the first place (like an animal for example) then you may face the same consequence whether you transgress or not and have no real reason to stick to it in that instance
Tl;DR animals have rights but we have no reason to respect those rights and cannot expect them to respect our own
