Cats tunneling through floor vents!

My mother-in-law's two cats do this. It started
because she generally blocks off the doors to the
living room when the Christmas tree is up, so they
can't knock off the ornaments and climb the tree.
They have discovered that by nudging the vent in
another room up, they can tunnel through and pop
up the vent in the living room anyway!
Now they do it all the time, to get in to her bedroom
and sleep.
One problem though.. one of them has gotten a little..
pudgy. So, she got stuck in one of the vent openings
a few weeks ago. They had to coax her to another
(bigger) vent to get her out.
It's the funniest thing to see, when you're sitting in the
room and a cat head pops up out of the floor.
Do anyone else's cats do this??

I had a couple cats do that! They were playing with some toys over the
vent and somehow hooked the vent with their claws and opened it! I
didn't discover it until another one of my cats kept watching the vent!
These were the return airvents, I walked over to another vent that was
connected and here was one of my cats looking at me. Cleaning the vents
later, I found a bunch of toys in there! It was like they were having a
party! I decided this was not a safe adventure so I had to secure those
vent tops. It would be just my luck that one of my cats would put a
bird in there! Sue

I have to admit that's pretty smart, and a cat head appearing out of
the vent like a little gopher *would* be funny. But I sure would be
uncomfortable about it. Can they get stuck somewhere under the floor
and not be able to get out?

I don't think so. Her house is on a crawl space, so the worst that
would happen is she'd have to crawl under there and disconnect the
vent.
She asked her HVAC guy if they could get to the furnace that way
and get hurt, he said no, there's something blocking their way,
I don't remember what.. I think maybe there's a long vertical vent
that they wouldn't be able to climb up?
Anyway, it's hilarious to watch.
