Depression
My suspicion was proven truth last night. The gray cat that comes around the back of the house and the gray cat that shows up at night at the front is actually the same cat. One of our dinner guests confirmed that for us. Now comes to think of it, they are both gray, both slim, both friendly toward Mike and I, and both very eagerly try to get in. Somehow under lamp light, the “night” cat had a longer nose so we always thought they were two different cats. How silly of us.
