Does anyone know when my guinea pigs will stop rumbling at each other? They're both females and I've had them for about 5 months now and they didn't do this for the first three weeks but now it's on and off. I really need to know because they're keeping me up at night when I have school in the morning. There's nowhere else to put them other than my room(I was advised not to have them outside, I wouldn't want them outside anyways because of cold weather). I've tried all sorts, distract them with food, give them separate beds. I'm getting a bigger cage for Christmas(hopefully) if that helps but they just don't stop.
