I have recently brought a 4-yr-old semi-feral/stray cat into the house after he was almost killed by a dog. His is living, for now, in one room and uses his two litter boxes like a champ. My question is, when he eventually moves into the entire house, do I need to put litter boxes in multiple rooms? Or will he return to his current room to use the litter box that he knows? Thank you!
