A lot of large herbivores (including horses, deer and cattle) do occasionally eat a meaty snack (typically a small bird or rodent) to get some nutrients they couldn’t get from a strictly plant only diet.

horses can eat meat and they do it sometimes but not all the time

Just cut it down the middle.
 
She’ll be happy.

Anon: I’ll do so if you promise to pay an equal portion of the bill.  
Starlight: Bitch, I’m a horse. Do you see all the pockets I don’t have to carry money around with me?  
Anon: Well, just like with the restaurant, no money equals no steak.

@Crazieman  
I wouldn’t say they eat it alot, but yes: horses do eat meat, but only when they can’t find any grass or hay to graze on or have been offered it as a treat/taken a bite of their owner’s meal behind their backs.

@Crazieman  
Yes, that would be my point. Since, presumably, AJ is not a drugged-up whackjob, and appears to be eating meat or an imitation thereof, the only reasonable conclusion is that ponies are at least part-time meat-eaters.
 
(The fact that this coincides with real horses to some extent, as I was aware of and as the description alludes to, is convenient, but not essential.)

@Wellwater  
Horses eat meat, a lot. Its not good for them, but they will, rather readily.

@Crystal Neighybánya  
But what kind of drugged-up whackjob makes — or eats — an imitation of some food that their biology and culture are utterly antithetical to?
 
(Admittedly, this reminds me of Chesteron’s hilarious bit comparing vegetarians’ mock turkeys to former cannibal tribesmen’s hypothetical mock-missionaries arranged out of joints of meat. One might reasonably “regard the proceedings … with something less than approval, and perhaps with something akin to alarm.” But it’s still worse when there should presumably be no historical reason for the practice in the first place.)

Who knew a man without a face could be so expressive?

“I bought this and I cooked it. Get your own steak.”

@Crazieman  
That could be imitation meat, though.

How about you eat MY piece of meat

@Background Pony #76C1  
Have we ever seen the ponies eat meat in the show?

@Crystal Neighybánya  
It also wasn’t made to handle certain foods that the ponies eat in the show just fine. Some of the things they eat on the show would be poisonous to real horses.

Here’s something equal, through MY effort and money, I was able to purchase this steak; you come along and demand a piece of my steak thorugh absolutely no effort of your own; who are you to demand something that which you didn’t earn?  
IT ISN’T EQUAL, COMMIE.

@Background Pony #76C1  
It’s not healthy for them, though. Their digestive systems aren’t made to handle meat.

@Crystal Neighybánya  
Horses can eat meat. But then my little ponies aren’t real horsed

You’re a HORSE. You don’t eat meat!

horses can eat meat and they do it sometimes but not all the time :^)

Think of it this way. I’m an alien in this world. I consider this a survival situation. Therefore, if you eat my dinner, you may become my dinner.

Get your own damn steak, you whorse.

Bu-But this steak shape is not equal~!
