Yes, about a year ago, while living near a housing development under construction, my roommates and I heard a loud, continuous, crying meow. We searched for nearly two hours, until we found a kitten trapped in one of the heater vents of a house under construction; sadly, due to it having metal walls, the kitten could not jump out. The vet estimated her at about two to three weeks old, so my roommates and I bottle-fed her for about a month. Now she belongs to one of our friends, has gained much weight, and lives happy.
To the person below me: same question.
