I don't think I'd have a problem eating horse... but at the same time I really have no desire too either.
Obviously, you're not hungry.
About 10 years ago my uncle had a young bobcat he found and raised it. He fed it 2.5lbs of horsemeat a day. He bought it from a slaughter house in 5lb ground bags. It was frozen and he'd chop it in half with a machete and throw in in the cage still frozen of the bobcat to eat later. He reintroduced back into the wild.
The bobcat was the largest one I'd ever seen. It was huge for a bobcat, probably close to 40lbs. It also never lifted.
