Fluttershy’s prey animal instinct kicks in. (Horse when trapped by predator)  
Gilda’s predator animal instinct also kicks in. (Griffon when grabbed the prey to eat)

True.

Vore is weird but the mouth is hot.

What I don’t get is just why you would want it to involve characters you like. I have occasionally found a few vore pictures appealing before, but only when they were characters I didn’t give a crap about. When the character being eaten is one I care about, it just makes me feel a little sad. And then even more so when the one doing the eating wouldn’t actually do that, like pictures with a pony eating one of her friends.
 
Still, this artist draws well enough that I like to look at these pictures just for the art, and try to ignore the content.

It’s rather difficult to understand ANY fetish that you don’t have, yourself.

i’ll never understand this fetish

Gilda is what you might call…an overzealous kisser.
