Animal suffering is a hard case, I'll grant that. But we're still standing in the same fog, just at a lower elevation. Seeing a valley full of pain tells us the terrain is rougher than we expected, not that no summit exists. To call it evidence against, you'd need to know what an infinite mind would consider worth the cost, and we don't. Once you admit we can't identify pointless suffering, you can't turn around and point to animal pain as if it's clearly pointless. It remains mysterious ground, not a slope pulling us away from God.
