Ok...if y'all saw my thread about the new member of our family in the gallery, you'll know that we thought he was a she, but he isn't. I don't have much experience in owning male kitties. Well..any male animals, really. So..what tips can you give me? What age do they generally start in with behaviors like being territorial and spraying and such? He is staying inside, Erik is getting all his shots, and once he's old enough, he will be neutered. Also, I need to introduce him to my cat, Aliyah, a spayed female who is around 4ish...any tips on that? I don't think I've ever had more than one cat at a time, so that's new to me, too! Thanks in advance!
