Patches does not open the closet doors; Romeo does. Romeo opens them, but forgets to close them.
Patches came along some time later, and saw the open door. So, she does what normal cats do: investigate.
I don’t think she found anything too interesting, because she came right out.
What is this strange thing? Do you think it’s safe?
It looks like Rusty is the brave one. He’s always the first to examine anything.
Romeo: “Well, Rusty, what’s your take on it?”
Rusty has to take another look before getting closer. He’s being careful.
Rusty: “It looks OK to me, but I think I’ll wait just a minute longer.”
In the end, none of them went in. It seems they had a conference, and decided not to venture into the tunnel. So, it’s on the floor in the patio, awaiting the first cat to play explorer. Maybe it’s the color red that’s putting them off? I move it around to try to get them interested, but nothing’s working. Oh well. On to the next “adventure.”
