About a week ago one of our cats, who was formerly hardly interested
in going outside, began staying out all the time.  At first it would
come back and spend the night in the house, but now it merely comes in
to eat, and then begins to meow until we let it go back out.

We have two cats, who are brothers from the same litter. We have a pet
door, and the cats have been free to go in and out as they please,
except in bad weather. Generally they are in by 10:00 PM and locked
down until early the next morning.  

Has anyone else experienced this sudden refusal of a cat to come in
the house?
