^ ahaha, I tried that! My mare's name is Sour, and I happen to be a bit of a sour-food addict so I often eat lemons just like normal fruits. One day I had one that I had peeled and decided to see if she would eat it...and she did xD she actually loves them! Horse like human I guess.
Sour's over all favorite though, are oranges, carrots, and tomatos. I'm not fond of tomatos at all so when I have one in my lunch, it always quietly slips into her mouth ;) she'll eat just about anything that I hand to her though.
