Defeated using only two pets
First pet: Cockroach (Scratch, survival, apocalypse), could be any pet with these abilities
Second pet: Leopard Frog (Water jet, healing wave, frog kiss), could also be any pet with these abilities
Third pet: Fel Flame but really could be any pet with a high HP (didn't get hit when i fought with these pets, but anything could happen), preferably aquatic so it takes less damage

Strategy
1. Sent cockroach in first, used apocalypse, immediately switched to leopard frog
2. Kept leopard frog in first using frog kiss, then using healing wave, and finally using water jet on cooldowns until frog dies (Mine died when apocalypse had two rounds left... if frog dies while apocalypse still has more than a couple rounds left just send your cockroach in to stall, using scratch until apocalypse and then survival before apocalypse hits)
3. Rat should be in undead phase and your cockroach should still have some health left, so stall for one more round with scratch until the rat dies again.
4. Cockroach should die with rat and then you have one pet left and win the battle.

I'm not a huge pet collector and was failing with a bunch of pets. Then my Chitterspine Skitterling (2/2/2) solo'd this.

Black Claw, Into Swarm.

The rats attacks are weak vs chitterspine

If it doesn't solo, youll get it so low, you can use a 1 shot pet like Iron starlette, chrominius, to finish it, then swap to a Rabbit or Anubisath to block if need be.

TL;DR Use Chitterspine Skitterling
