Hi Im new to this site and wondered if anyone can give me some advice? I have a 1 and half year old, male, neutoured rescue cat that ive now had 7months, he has settled in really well and you would think he had lived her all his life. Im now considering getting a second rescue cat but dont know what type would be appropriate. Should I get another boy or girl? should it be much younger so Harley feels like the boss? and how likely will Harley accept an intruder to our home? Any advice please
