1.Animals, that do not kick, are always unexcitable;
2.Donkeys have no horns;
3.A buffalo can always toss one over a gate;
4.No animals that kick are easy to swallow;
5.No hornless animal can toss one over a gate;
6.All animals are excitable, except buffaloes.

Answer 2

By 1 and 6, only buffalo do not kick.
By 4, only buffalo can be easy to swallow.

There are other valid conclusions, like buffalo have horns and are not donkeys, and you don't need worry about being tossed over a gate by a donkey, but none that draws all six propositions together. Donkeys can't be easy to swallow, because they do kick. I don't really think this holds together as a sorites.
