A friend just had a brilliant idea, though a bit odd, for the meat issue... Lizard tails. They pop off with no health risks to the animal, and they grow back. infinite meat source, no killing.
@freemo might be able to do this with starfish and a few other organisms too! but there's a lot of good research pointing towards using bacteria to "grow" meat, probably a better route lol. i don't think lizard tails are very meaty, and they take a long time to grow
