@glennpotvin,
I don't doubt that this happened, though it's not very common for it to happen from wild birds of prey. For example, my close friend, who lives within 5 miles of Boston MA, lost his domestic cat to some sort wild coyote at the back doorstep of his house early one morning.
He was shocked one night when he heard a ruckus at 3 am at his backdoor. When he investigated, he got there in time to see a wild coyote (team) running off with his cat, which, mercifully, was already dead. This was and is a densely populated neighborhood with regular urban traffic and normal street lighting.
Perhaps you recognize there's a difference between your location and the majority of others locations. However, the rarity of such an attack is not zero chance. You have my sympathy.
