We will soon have a new member of the household. We'd like to confine the cat to half the house but allow people to roam freely. A doggy gate won't work since cats can jump over one. We have a long, standard width hallway where we can put in some temporary "doorway" (the cat will be here less than a year). I looked at according doors but they are not very pleasing to the eye. A permanent door is out as I want to limit damage to the hallway. Any ideas?
