Pizza Cat, Cameraman Cat, Slime Cat, Immortal Yukimura, Assassin/Teacher BearCar and similar units are very helpful in this stage. Balrog Cat can also be used, but only if you can time him correctly to avoid both Queen Bee's attacks and the low-level peons in the stage.
Lineup: Slime Cat, Fishman Cat, Pizza Cat, 2-3 meatshields, 2-3 wave or LD attackers and some eventual combos or Ubers
Items: Rich Cat and Sniper
Spawn in Fishman to stall Queen Bee and do some free early damage. When the first Duche spawns, spawn your Slime Cat to wave attack Bakoo. Start meatshielding with Manic Eraser and try to kill Duche with long distance or wave attackers, such as Manic Macho Legs, Housewife Cat, or Pizza Cat (with the wave talent). You can speed up Duche's death by using Teacher Bear Cat. Stop meatshielding as soon as you have killed Duche. You can also use Bomber Cat to help you avoid Bakoo's attacks. Repeat the process with the Dagshunds. Eventually you'll have killed all the Bakoos, allowing you to push past Queen Bee and win.
The amount of skill (or luck) needed for this strategy is very high, as you must still time you cats properly.
Strategy 2 (Ft. Kasa Jizo)
Lineup: Biohazard + Boney Bone, A. Bahamut, Bombercat, Jizo and/or Can Can, Cameraman, Macho Crystal Cat, meatshields.
Level up your Worker to level 3. Lure Queen Bee to your base while stalling the peons with meatshields, although you can also use Green Shell Cat. When the first Duche arrives, build up a stack of attackers, such as Can Can Cat, Jizo, Cameraman, Awakened Bahamut, etc. You can also spawn one Bomber Cat, although it is optional. When Queen Bee approaches your base, fire your cat cannon to interrupt its first attack, preserving your stack. If you have A. Bahamut as your main attacker, you could also consider using a Curseblast Cat Cannon, where the timing is easier at the cost of your stack getting knocked back, potentially letting them be attacked again by Queen Bee. The first Duche should have died and your stack will move forwards. At this point, it is important to refrain from spawning any meatshields. Use Bomber Cat to try to preserve your stack, which can knock back the Bakoos and Queen Bee. Spawn in Macho Crystal Cat when Dagshund arrives, but make sure that you do not trigger Bakoo's attack while doing so. A. Bahamut can get one shot by Dagshund but luckily outranges him. Combined with Macho Crystal Cat's slow, you can kill him before he attacks. At this point, anti-floating cats will be very helpful, such as Saber Alter or Fishman Cat. If you can time well, time your cats to avoid Queen Bee's attacks. If you can't time well, then spam everything and hope for the best.
