Bunch Of Bites

[PeanutButter]

I have two guinea pigs. I had peanut first and then I brought in rusty so peanut wouldn't be lonely. Peanut is an adult and rusty is a baby. For the first month, after peanut established dominance, they were getting along well. They would cuddle and protect each other. Recently, I find peanut intimidating rusty and scaring him. Peanut has also began biting me when they're both on my lap. I don't know what's going on
