What animals are considered acceptable to eat is largely cultural. I'm sure some people feel about cows/chickens the way we feel about cats, and would say the same if I died from eating poisoned beef or chicken stew. . .I dunno. As long as I eat meat, I don't feel that I can judge anybody else for eating meat, no matter what kind of meat it is.
Although I will say that anyone who makes so many business enemies might want to be careful about what someone might slip into his stew.
