Does "No horned animal is a unicorn" mean that
1. We have observed every horned animal.
2. All the horned animals we observed were not unicorns?

seems to me that when you add "All unicorns are horned animals."

You either have to say that unicorns don't exist, scratch that, that there is no evidence for the existance of unicorns,or
We have not observed all-horned animals.
Or that some unicorns aren't horned animals.
