Today had been a good day so far. He had spent the afternoon with Flair and the children, watching them play and grow, enjoying these precious few treasures that life had allowed him to keep. As night settled over the forest, he'd pulled himself away to do his part as a member of the pack. He chose this time to patrol first, checking the integrity of their caches and markers, allowing his paws to take him to the farther reaches of the Falls.
It was here that he picked up an invading scent, one that made his nose wrinkle and his lips curl into a disgusted sneer. An uncharacteristic bolt of anger rang through him from crown to tail tip, and he had to take a moment to breathe (1... 2... 3) in order to be able to think straight. Logically, rather than only emotionally.
Chan tipped back his head and howled, his call carrying strongly through the air to communicate a single word: cat.
