Hi and welcome to Pettalk! i know there are probably other people here who have more knowledge and more cats on this subject that can help you...but i'll give my 2 cents worth

I think since your cat is still young, introducing a male would probably not be a problem. And if your cat is layed back enough, it may not even be a problem once he was older. My mom has a full grown adult male and introduced a male kitten later on and they are the best of friends now. I had a female first and introduced a male and they are the best of friends now too. In both of these situations, the cats are super friendly. From what i understand, females can be more territorial, if they are the first cat in the house and a second cat is introduced...but i guess there is also the thing of male dominace. But if your cat is layed back and friendly...you would probably be fine either way. I think i have heard more often, that 2 females can actually be harder to introduce to eah other than males.

ANyway, congrats on your cat and good luck with your next one...it is so nice for them to have a playmate...i am glad we got a second one!
