I hate squirrels. Just because they've got a bushier tail, it doesn't mean that they're cute and any less scary than rats.
I personally think rats seem a bit smarter.
Besides, they're basically cousins, rats and squirrels.
Ever try and watch a squirrel cross a street? They look schizophrenic for god's sake. Pick a goddamn direction and stick to it!
Personally, I'd have enjoyed seeing that squirrel get run over. At my campus, I see only squirrels scavenging in dustbins.
