In May/June my friend wants me to pigsit while she goes on a trip. She has a mom and a daughter, I have the daughter's brother and sister from the mom's litter. When she brings her piggies over, do they need to be in their own cage? or is it OK if I put them in with my girl for the week or so when she's gone? I think my Cinnamon would love having the other girls with her for the time being but I don't want to traumatize them when they get separated and the other two go home... Any advice? Thanks!!
