My kids call our guinea pigs Love Nauts. They hated each other at first but now, they starting to co-exist with each other even in one cage. We still separate them every night but we let them get to know each other during the day in a big box.
Penelope ks a long haired perivian guinea pig so we get to ix her hair with stuff. As long as you are gentle, she's fine with it.
Dunkin seems to enjoy his companion now. He still get jumpy at times but he is getting better withdealong with Penelope. I still miss our bunnies but these guinea pigs are good replacement for them especially for the kids. They were devastated when our ast bunny died because Wubzy was a very good pet who love to hang out with us.
