I beat bun bun teacher (Lvl 3-48) without max'ed treasures. But it was really hard and he got really close to my base. You don't have to get all treasures, but it's recommended that you get close to it.

Cat attack, cat health, and efficiency (how fast you get money) are highly recommended but not mandatory. Like Nursewuffa said, you need drags to be able to take 2 hits from bun bun.

I would say the only skill that really need at 100% is Cat production. The wall/macho cat spam is really important, and having a slower production rate will let him get get closer much faster.

On a side note, once you beat the stage and unlock Bahamut cat, farming this stage becomes much easier.
