Now that I am running a homeless shelter for stray cats, I thought I'd give an update.
We have a squatter.
According to the trail cam, a cat is coming every night.
Drinking water and going inside the shelter.
Last night the stray arrived just after midnight and didn't leave until almost dawn.
I call this a major success!
The food dish was empty today, so I refilled it and the water, I expect my squatter will be back later,
as the temps are hovering just under the zero mark.
(I think the thermometer in my trail cam is suffering from the cold.)
