Per buglady:
............Clicker?? Cats can be clicker trained. Some of mine come
when called. When they first come in the house, every time I put food
in front of them I say their name over and over, for months. Soon they
know their name at least. Now, whether or not they're in the mood to
respond, well, that's another matter! I have one I have to round up to
come in for the night. He may take 15 minutes to get to me, but always
comes in the end. Then he has to run out in the street and roll around
for me to pick him up.

We did something like that using cat junk food.

Originally, it was a means to herd the cat into the rec room where it
spends the night. We would put a few pellets of junk food on the plate
along with the regular stuff, let it get a taste, and then walk the
plate down to the rec room.

Now, at 18:30 or so this thing is all over us to get on with it... It
*wants* to go down there.

I don't know what they put in that stuff but our cat sure does like it.

So... if it gets out of the house at dusk or after dark, I just grab a
container of cat junk food and shake it. Cat hears the noise and come
*running*.
