Yeah when you think a lot of emotion is need based. Like your horse obviously had a need to be with her previous home, until she got over it. I think there's no question about it that animals have emotion, just in a different way. I think sometimes we give animals human qualities, forgetting that they can't think in the same way as us, so although they feel emotion, it's not like they are thinking "I'm so sad right now", they just sort of... are. It's tricky to explain. I guess a good way to put it would be, say you went into your bedroom, and someone leaps out at you. Your reaction may then be to punch them or something, because you are scared or angry etc. Except you don't do it
because you're angry, you do it as a reaction, but the emotion is still very much there. I don't know if that makes sense, but that's sort of what I mean.
