#19 - Pigeon

Reason: It's a rat...with wings

There are a number of reasons that Dom hates Pigeons, but first and foremost is the fact that they are "flying rats." Also mentioned previously, Dom hates cripples. As an undergrad, Dom spent many a lunch outside of commons amongst these feathered transients. Each one had their own disgusting disfigurement that would ruin poor Dom's appetite.
