Strategy[]
Lure the enemies close to your base so the Surge Base can't reach your cats, then use anti-Alien cats such as Corrupted Psychocat, Seafarer Cat, Chill Cat and talented Can Can Cat to kill/slow them. Remember to bring a Barrier Breaker for the UltraBaaBaas, like Loincloth Cat or The Kitty of Liberty. Since there are several backliners, Golfer Cat is good for killing them with his Long Distance ability.
