...This pretty nice, actually...
Um, vegetarianism is a lifestyle, typically in omnivores. And the problem lies exactly in that 'something'
Them being vegetarian is fanon, IIRC.If I recall correctly, there are vegetarian hot dogs.
Then, there's always that condiment used mostly for meat
Well, the problem is also with pig on AJ's far. Pigs are actually pretty lean animals, to make them fat you must overfed them. We see Cutie Mark Crusaders do just, by dumping a lot of food for them.Wouldn't be a big deal no matter what, but I don't find that to be conclusive evidence that all ponies eat meat.
They also seem to be unintelligent, as you said.
So, either AJ's farm wastes 90% of the food to produce enough scraps... Or they're being specially fattened for some reason...
