Any sighting of the elusive Big Cat?

This is what im confused about. Fiel said jaira disapears 15 minutes after it spawns. But a blue message appears when it spawns. Theres no way someone would cc to a channel just when jaira spawns (maybe once, but multiple people doing it, I dont think so)

It makes me think that jaira does wait till someone cc's into the channel, blue text appears, and if jaira does not get captured within 15 minutes, it dissapears.

Blue text appears on the ch when you cc into it. Doesn't matter how long the boss how spawned. Someone could be in the middle of hitting it, and you'll see the text. Test it out on an area boss to see proof.
