Help determining where to start to investigate moisture

We were removing the baseboard to replace carpet. There is an inside wall that separates two rooms that has an entryway between the two rooms. On one sode (where were were removing the base board) we have noticed a wet area about 1/4 to 1/2 inch from the wall and less than 4 inches long.

This is an inside wall, so I checked on the other side of the wall and it is completely dry. I have included some photographs.

This photograph shows the placement of this wall. It is between two rooms, with a large doorway cut between the two rooms.

One of the photographs (the one turned sideways, sorry) shows what I mean by inside wall.

The other two show that it looks like this has been an ongoing problem with this area. A neighbor suggested one of my cats or dogs peed here, but it does not smell like urine. It looks like an ongoing problem because you can see that the steel part is rusted and there is some mold/mildew growing.

Is there any idea where to start to look for what is going on here?

I have looked a the entire wall, and this is the only place where it looks like there has been any moisture.

Again, I am at a loss as to whom to call to help diagnose this problem.

Any help is much appreciated!

Was the wall built after the carpet was installed? What's above the wall? I wouldn't rule out the dog just yet. How many dogs & cats do you have?

We have 3 adult cats and 2 puppies (border collies) that will be 11 months old February 1. The wall was there before the carpet was installed. This is in a one-story rambler. The only thing above the wall is an attic.

Thank you for your help. I just have no idea where to begin to look at the source of the moisture.

I would look in the attic to see if it's wet above the spot with the rust. Do you have steam heat? There could be a header pipe below the floor that's leaking. The pressure would send the moisture upwards a little.

I would not rule out the animals. All animals will urinate in the house.

Is it actively WET or just that the corner bead has rust on it? Corner beads rust all the time, it could be an old issue that was resolved but the residual moisture caused some rust.
