Strategy 1: This stage is pretty straightforward, but you'll need to have a lot of Area Attackers. You'll need at least 3 meatshields here: Mohawk Cat, Eraser Cat, and Crazed Wall Cat. The reason for this is that you'll face a Skelecat horde and you need to fight your way through.
First, after a few seconds a Skelecat will spawn along with some Squire Rels. Stall him with one meatshield until you're able to spawn Bahamut Cat. By this point the horde has already shown itself, so you'll need to build up Area attackers while maintaining a good meatshield spam.
If you have Ururun Wolf, that would help a lot in ensuring that the Skelecats won't get close to your attackers.
Once you get to the base, it will only take a few seconds for your cats to dispatch it since it only has 150,000 health.
Strategy 2: Simply one of the easiest awakened stages of all. Using area attackers will help the most.
Line up: 3 Meatshields, Paris, Crazed UFO, Flying Cat, Area attackers of your choice with high DPS, Crazed Bahamut (Awakened is better) and maybe Ururun if you have it.
The first will spawn, you have to get your money at least to 2000 before you start spawning your cats. When the Skelecat is two thirds of the way to your base start spamming your meatshields along with Paris and Crazed UFOs. By the time you kill it a horde of them will come out. Spawn your Paris, Crazed UFOs, Flying Cats and area attackers now; You will gain money quickly. Spawn in Bahamut with all the other cats. You've pretty much won now.
