My idea for the next update
In a future update, an option could be added where the player could choose the maximum number of cats they would like in the clan. When there are a lot of cats, it is harder to focus on individual cats. And even if the player does not add many loners etc., some cats can get pregnant and later there will be another kits again. If the player, for example, entered that they want a maximum of 20 cats in the clan, then if they already had 15 of them, there would be a smaller chance of finding loners and other cats who could potentially join the clan. There would also be a smaller chance of shecats getting pregnant. With 19 cats, if a queen was pregnant, she would only have 1 kit and there would be no chance of finding a loner on patrols, unless a random cat in the clan died.
I hope you like my idea.
