I've had cats all my life but they are always outdoor cats. My DM is a cat lover too, she is elderly, and is thinking about getting another cat, but is unnecessarily worried about traffic etc, other cats and so on. However a cat would be a great companion for her. Some of her local cat sanctuaries rehome "indoor cats", and specify that this is ideal for the elderly owner. I have zippo experience of the indoor cat: does anyone think this is feasible? Would the cat not want to go out? And what if the door is left open? Any thoughts welcome!
