Even if the cat is happier, there will be a human who isn't. I used to have a neighbour who swore her cat never left her townhouse yard, but we often saw it over looking in the window at our cats, and the basement window to the room where our cats looked out was YELLOW with cat pee spray. I have stopped to remove the body of a cat from a roadway, and it wasn't pleasant.
I say lots and lots of beandip will save you. Have several other topics ready to switch to.
