Well to explain my tittle I suppose I should explain how I adopted my little furry wonders. I had to buy them from a friend. But she had lied about the condition they were in. (No they weren't actually in bad health or anything.) But they had no food or water bottle, The "Cage" was a cat carrier, and the "Toy" was a hamser ball. Anyways the point is that they had told us that they were both females... Now, after almost having had them for a year, I've notice my bigger one Godiva has been gaining weight about her hips. I looked at her more closely after reading on how males will act towards female and vice versa, and I am suspecting that she is pregnant. Could that actually possible? I mean I've had them together for almost a year thinking they were both female. (My mom and I checked.) But Im starting to wonder if I might be wrong. I though maybe I've been feeding them too much, but then again I am suspecting that thats not the case. Because Mocha (The other Guinea Pig) hasn't gained as much, and still has eaten as much as Godiva has. Could any one tell me anything to help me find out whats going on?
