It is probably a cultural thing. I’ve read somewhere that in SE Asia the rats from the rice / grain fields are often captured and eaten. That they are cleaner and healthier than ‘city / garbage’ eating rats. I’m not sure if this is true… but If their chef knows what he’s doing, the rat(tatooie) may not come back and bite them in the health inspection. *Besides many people in the US eat Squirrel and a squirrel is nothing more than a rat with good PR.
