Lucky too that it did not plug the vent pipe itself. A plugged vent can
mean traps siphoning, bad odors in the house, and frustration trying to
figure WTF is going on.

My "stuck animal" story involves a grackle, IIRC. I was replacing the
gas water heater and in reconnecting the 4" exhaust pipe I discovered
the very dead grackle inside it. Now a grackle is a pretty large bird
and 4" isn't a very large pipe. It scared me to think how close we'd
come to having that pipe blocked and fumes coming into the house.
