A friend's cat is is soon to have kittens and being a known cat lover she has offered me one which I would love to take BUT current cat is my absolute darling and I don't want him to end up feeling displaced or running away. I'd hope they can live harmoniously together.
Current cat has not lived with other cats but is very sociable with other cats in the neighbourhood.
I've had multiple cats previously but always got them at the same time and were related.
Will this work?
