Yeah no, I've seen the video where a horse eats a duck or chicken (or cat?) so I'm definitely on edge when I see some video of a horse's mouth near a small animal.
It's a pretty easy one to come across, a bunch of baby chicks are clucking around and a horse just leans down and eats one whole.
Pretty crazy, but I worry that the horse wanted the cats ear or something lol
I've stumbled upon the clip too, its pretty messed up. I've spent a fair bit of time around horses so I know they're mostly gentle giants with unique personalities (obviously there are the odd outliers) but that clip totally makes you jump and go woah!
