Strategy
This is a fairly simple yet challenging level; the best way to win is by not using meatshields at all but instead fight with only ranged attackers so a Crazed Gross doesn't hit a meatshield and trigger a Wave Attack. If the player posseses a wave blocker such as Octopus Cat, it can pretty much nullify the stage totally and utterly.
Strategy 1 (Uberless)
Lineup: Macho Leg Cat, Paris Cat, King Dragon Cat, Jamiera Cat, Valkyrie Cat and Bahamut Cat. Don't use any meatshields, maybe add Crazed Dragon, Uber Rares or Cat Combos in the last slots.
Battle: start by saving money, and when the first Crazed Gross Cat is halfway to the base, spawn Macho Leg, Paris Cat, Dragon Cat and Jamiera Cat. Spawn Bahamut Cat when you have enough money. The main method for this strategy is to build up an army of King Dragon Cats and Paris Cats and hope to not get hit by waves too often.
Do not let the Crazed Gross cats stack or get too close to your base as their waves will keep knocking your attackers behind your base and make them useless without proper timing.
Strategy 2 (Wave Shield)
The player does not need any high level cats for this strategy except for a wave blocker.
If you have a Wave Shield such as Octopus Cat or Cat Machine, the level becomes a joke as the Crazed Gross Cats' Single Target will only hit one cat at a time, so just summon the cat with many meatshields, some attackers and fight as you would do in a regular level. Any lineup with a Wave Shield and 3-4 75¢ meatshield will work. The best strategy would be to have several Octopus Cats and many 75¢ meatshields in the front while cats such as Paris, Dragon, Crazed Bahamut and True Valkyrie stack up in the back. Anti-Traitless Ubers would also help.
