If you are veggie (or know any veggies)

[Trills]

Would you (or they) eat meat if it had been grown in a test tube?

Would anyone? Yeurch.

I would think the 'mixed with blood' part could be an issue...

NO!
Im vegi becuase i dont like meat, NOT because of where it comes from.(I am sorry to say, but i am not an animal lover at all)
I just dont like it.

My sisters a veggie because she doesn't like meat so no she wouldn't.

Personally I probably would if they could make it properly vegetarian (e.g. not including animal blood as it apparently does at the moment) and if it tasted nice.

The latter especially is a big 'if' though! I can't imagine it being very pleasant...

What if they were well-tended free-range happy cows, who gave a safe amount of blood at appropriate intervals? Like happy dairy cows, only with needles instead of milking machines?

No I wouldn't, because I'm veggie because I think eating meat is weird, not because I think killing animals is wrong.
