Animals don't have natural rights. If the animals in question are a person's property, there's nothing s\he can possibly to do them that should constitute a legal crime, as long as no self-owning entities (i.e. other human beings) are harmed in the process.
That said, torturing animals is unethical and clearly undesirable, and most people would choose to expose and ostracize a person who is cruel to animals. Furthermore, establishments like homeowners' associations and pet ownership societies could make cruelty to animals a punishable offense through contract law. This is how a free society would deal with people like that - without ever initiating aggression against them.
This dude has serious issues. That's my expert opinion.
He needs extensive psychological help.
But he'll just end up in jail for a couple of years and be released just as bugnuts crazy as he was before he went there if not worse.

Some "evolved" animals (like monkeys and most other big mammals, like cats or dogs) have "humane characteristics": they can communicate, they can interact with us, they have feelings...there is no difference that could justify a total absence of rights, or that violence against them is "less bad" than violence against humans
Of course that doesn't really apply to ants or snails (yet it's still wrong to kill them just for the pleasure)
