I see it so often it doesn't even phase me anymore.
It's exactly like rabies in a rac00n.
Racc00ns when they have rabies go blind so they will run around in a circle, flop all abound while screaming, bump into shyt.
These deer look mad drunk. They will run in to cars, buildings, they start to go blind too so they'll run into traffic without hesitating. Their coordination is all off so they will stumble and backtrack, circle. Just call animal control they will put them down and no you don't eat them .
The physical deterioration is like a dog with mange.
