<human>: Can you provide a brief overview of the text?

I just got a new kitten and I have 2 other cats. One is an outside cat, she stays there all day every day. She is allowed to come inside but chooses not too. My other cat who is an inside cat loves the outdoor cat but she will not let him touch her, so I figured that he was at least semi-okay with other cats as he REALLY would love to interact with the outdoor cat. The indoor cat absolutely adores our dog as well. Now that I've brought a new kitten in he has suddenly changed his ways. He does not like the smell of the kitten at all and I don't know what to do. I introduced them the minute I got home and am now realising that that was a huge mistake. 

Does it just take time? Is there something I can do to make my indoor cat warm up to the new kitten? Or have I just made a mistake in getting a kitten all together?
<bot>: Bought new kitten, indoor cat who is [semi]-okay with outdoor cat now hates all cats. Wait it out?
