Hi, a couple of months ago I was given a young female and she turned out to be pregnant. Well she had 2 females and 1 male, they are 3 weeks old today and I understand that I should separate the male now. My question is will he be alright on his own, I have no other male guineapigs to put him with. It is winter here and I am worried he will get cold on his own. Do you have any suggestions ? Thanks
