ok so i recently had one of my two guinea pigs die so i decided I was going to get a new guinea pig for her to have a friend. I called my local spca and they said they have babies so im going to get a girl one. My guinea pig is an adult but she is still young(only about 1 and a half) and she is still hyper like a baby so i think she would enjoy having a younger pig around to play with.I need some tips on introducing them please!! Also should i get another cage to keep the younger one in because i dont think its a good idea to let them live together automatically. Thanks!
