Related question: I have two cats who were rescued feral kittens. They
did all right for a few years, but I then adopted another kitten who hissed
at them constantly. They decided to hell with it and moved out of the house
and now eat their meals on the back porch.

It's cold and dangerous out there. I want them to be indoor cats again.
What's the best way to handle this? Should I just catch them and lock
them inside? Guaranteed at least one of them will pee on things if I do
this, but I guess I could drape plastic over anything that doesn't clean
easily.
