I'm glad your daughter likes them. They're adorable! Princess and Skittles, eh? Good names. Mine are Pepsi and Buddy[so original, I know] Pepsi had to get neutered, but it didn't seem to bug him a bit. My guinea pigs are 4 goingon 5 years old.Guinea pigs live 4-6 years, but can live to be older than 8 if well taken care of. I hope you and your family enjoy the piggies!
