Crazy cat Lady 😀 Evil bitch this one.
We use a few combos of strats out there, we have a hunter/immolation trap, DK/D&D, Pally/Consecrate etc to pull them over, we stand at the top of the stars and the end of their patrol and we hide 😀 We have an OT for the 2 cats and a tank for the boss. Generally our Prot warrior takes the 2 cats and our feral takes the boss.
We DPS one cat then the other, popping heroism at the start. If we are having a good DPS night, both cats will be down before the first scream, otherwise the second cat will be at approx 10% health and gets burned down pretty quickly once we get back.
We let the OT pick up the feral defender as much as possible and we don’t DPS it all, just let the general AOE splash damage kill it, at about 5% health we try and move it away from the boss and if not possible the tank starts moving the boss away for the void sphere that spawns. once the defender is down we move the boss to the the other end of the platform not even very far really, enough that if people get feared it isn’t in the void zone.
Generally we get 2 spawns of the feral defender and only one void zone before the boss is killed.
