Cougars were dangerous beasts indeed - even the Guard had a few run-ins with the territorial felines. Amon's brow raised at the initial mention of the attack, and then there was a brief moment of concern - but this too evaporated. Lucky indeed. That cougar probably thought Fox was an easy meal, what with her ehm, smallness.
He didn't describe her in such a way to be vindictive, just pointing out a fact. Fox was a tiny girl compared to Amon - so to him, it was logical that a big cat like a cougar would mistake her for a child, or something similar.
Still, he played it safe. Ah, but don't be telling her I said that. She's a little one, but seems pretty dang feisty.
She probably gave that cougar a run for its money. But, knowing now that there was a threat somewhere in the territory, lurking just out of sight and everything... Amon caught upon the idea to hunt it down. Where was it spotted? Maybe we should get some more bodies together and chase it out fer good. Or kill it.
