As a vegan and bunny loving Frau, I hate that I'm having to type this but pet rabbits are not safe for human consumption especially if they have been vaccinated or medicated for previous conditions. Genetically they are not suitable either especially the fancy breeds (which shouldn't exist because of associated health issues but that's a whole other issue).
If a person was going to eat rabbit meat, it would have to be from a rabbit that was bred for the purpose and medicated on 'safe for consumption' wormers etc. Everything would have to adhere to industry standards too.
I hope to goodness Jack wasn't cruel enough to eat poor Dash. She will forever be an evil bleep in my eyes for how she treats animals.
