I currently eat a fair amount of Quorn, due to my girlfriend fiance being a vegetarian, and it being cheaper than meat. (Also in most meals, it tastes just as good as mince).
Quorn is made from microbial biomass, which is a filamentous fungus which is grown in a fermenter and then sold as food.
So yeah, seeing as i am currently happy eating mould, i think cloned animal cells would be perfectly fine.
