That was weird!

As I was sitting here in my home office/second bedroom, I heard a faint snoring... In, out. In, out. It was a bit odd, it sounded like the dog, but he is outside, and I though the cats were elsewhere. Still, in, out. In, out. Sigh, snore.
I started walking around the room and quickly realized it was near the window. In and out, In and out. So where is the cat? She's not on the radiator, and I don't see her near it. Sigh in, whistly snore out.
Now I'm on my hands and knees trying to find the cat. Sigh in, whistly snore out.
Ahah! It's under the radiator cover! And it's not the cat, it's the vent! Steam pushing air out (whistle) , condensing and vacuum pulling air back in.
In 30 years in this house, I have never heard that sound before. Guess I need to check that vent.

Maybe, or maybe it's doing exactly what it should. Or maybe there's water collecting in your pipes that is making the steam collapse a bit.
