We have two cats - a 9yo female and 2yo male. Both laidback friendly cats who rub along OK most of the time - the female is more independent, the male more attention-seeking and playful. He sometimes tries to initiate play with the female which tends to result in him getting a swipe. from her He's always excited to see other neighbourhood cats in the garden. I'm tempted to get another young cat as company for the male. Is this a good idea or likely to end in disaster?
