two hypotheticals: pregnancy and twins?

1. I'd be concerned with the fact that allowing something like that leaves room for that female to actually stay in-game missed by CM eyes and then it would be against the rule like a player entering the game pregnant so a no from me there too

2. I don't really see a problem with this one and while realistically they probably wouldn't last longer than a few weeks I'd say a bit longer wouldn't hurt since most pup players don't post much the first few weeks? That and this is a semi-realistic game so to allow them to live a month or two would give players the chance to explore that issue/cope with having kids like that. As for two separate players, I'd imagine it like players who play twins? Separate accounts for the individual wolves but they're just always in each other's threads since they are literally joined at the hip together.
