Technically you don't need all the treasures, but unless you're really, really good at cat spam, treasures make the level much easier to beat. You want:

Efficiency - Near max, or max. You need more cat $ to keep up the spam

Production - Max. Less time = more and quicker production of cats

HP - Max. You need dragon cats to be able to survive one hit from Bun Bun

Attack - As high as possible. More attack = the faster you kill Bun Bun
