Eeeep, you may wanna watch out there. Here on the forum we have had so many "accidents" involving the friendly so called dis-interested house cat. I guess it is one of those things people figure will never happen but actually does.
Anywhoo, I was totally amazed both your females were prego, I bet you were too. lol Thanks for sharing the story of them baby sitting for each other that was just WAY tooo cute :P
Now your colony is at 7 members! Dang, it took you a month to surpass my 4. With those statistics I am pretty happy I have all females and no males hah.
