Since most units can't directly outrange Professor A. or Elder Sloth, the best strategy is to snipe them by using the Otta-smack-us as "stepping stones" for Long Distance/Wave Attackers. Generally, however, anything more than two Otta-smack-us will end up pushing into your ranged units, so try to find a good balance between offense and defense.
Lineup: Manic Mohawk Cat (30), Manic Eraser Cat (30), Eraser Cat (20+50), Manic Macho Legs (30), Zamboney Cat (30), Manic Flying Cat (30), Prisoner Cat (40), Awakened Mina (30), Schoolbus Nyandam (30) Awakened Bahamut Cat/Cyberpunk Cat (30)
Awakened Bahamut is generally superfluous here - the only real use for him is to be an "emergency button" against the Otta-smack-us if they start pushing too much - so Cyberpunk Cat is preferred.
Try to play the beginning in such a way that Manic Macho Legs kills two of the Mistress Celeboodles and leaves one alive. Lure this third Mistress Celeboodle to your base, take her out with a Zamboney (fire the Cat Cannon if Those Guys are in the way), and begin the lengthy process of stacking Long Distance attackers.
Once you feel you have a big enough stack, start spamming everything you have (except Bahamut, if you chose him over Cyberpunk). After you defeat the first group of Otta-smack-us, your Manic Flying Cats should die off. From here on out, it's just a matter of using the Ottas as a means to snipe Professor A, and henceforth you should never have more than two Manic Flying Cats on the screen at a time.
