Recently my guinea pigs picked up chirping and wheeking at specifically about 3 in the morning and honestly, it is driving me INSANE!! I have to sleep in the spare bedroom downstairs because it is so bad. I don't know why they picked this up but it isn't going away and getting better. All of the sudden I will get woken up by this chorus of wheeking piggies. They arn't low on any supply or anything. Please help!
