Introducing a new cat to a resident cat should be done very carefully and the correct steps taken so that the introduction goes smoothly.
However smoothly an introduction has gone sometimes aggression can flair up and can seem like it has developed out of no-where.The reasons can be very complex and the puzzle, as to why this has started, may need to be deciphered by a cat behaviourist.
