As seen in this story
Toronto, Ont. April 10, 2010: I came upon this poor squirrel lying in the middle of the road while riding my bike today. She had just been struck by a van, moments before I arrived on the scene. I thought she may still be alive, as there wasn't any blood or guts oozing anywhere. She was still warm to the touch, but I couldn't find a pulse.
I gently picked up her limp, furry body in one hand and gently placed her on a grassy spot on the other side of the sidewalk. I inspected her a little closer and it appeared like she was still nursing. I patted her gently, hoping that this turn of events didn't create orphans of her offspring.
I called Toronto Animal Services and they instructed me to put her in a bag and leave her on the porch, where they'll come to collect her tomorrow morning. They told me they get calls for about a dozen squirrels a day, as well as about a dozen raccoons and several cats that end up as roadkill.
Be careful out there.
