Flashback to my first pets

We didn't have pets before 1985, so this one is mid-1986. We were looking after the 3 adult guinea pigs Socksy (m), Cheeky (f) and Cappucino (f) (in my arms on the left) for friends who were away, and while we had them, the babies appeared (in my sister's arms on the right) I can't for the life of me remember any of their names except Mimi. We kept the babies as our pets, until they were found dead in their cage one morning. They were untouched, but a dog had obviously been at the cage, and we assume they literally died of fright!
