Sadly, the laws we have in place in North America to protect animals are very rarely enforced, and often not until it's too late for the animals in question. At most, the guilty party receives a laughable jail sentence (less than 60 days) or more commonly, a fine.
OP, why don't you just go trap some wild animals and cage them? They're free! You could just keep them until they starve to death and then replace them with new ones once you're bored with the corpses. You won't even have to pay for food that way! There's entertainment value for your money! That's what this is about, right?
Honestly, where do you draw the line? You can't put a 'value' on a living, feeling thing - least of all for personal entertainment.
