Hey, SO I was here around a month against with concerns over my new Guinea pigs, Trevor, behaviour. He bites at the bars a lot, which has made neighbours complain and now we're moving him into a 6 foot long, foot 1/2 wide "fish tank" with an open top. He's very very skittish even though I've done everything possible to try and maintain trust with him, he's coming up to 3 1/2 months old now, I think. He was a very cuddly guy and used to pancake all the time on my legs and chest, he seemed very comfortable. Not sure if I did something wrong but one day he switched and now I can hardly touch him without him "popcorning" and trying to bite me. Is he just hormonal? He does have MASSIVE balls. Is there anything I can do to stop him biting and his weird so called popcorning? He definetly cannot control himself and ends up rolling on his back a lot and won't let me touch him. I'll attach a recent video of him doing it. Thanks.
