I want to get my Vodka(piggy) a roomate. But first I should really build my pig a new friend. Is it ever too late to introduce a friend? I've only had the pig for a week and I understand you have to introduce the pigs slowly (like at playtime) and quarantine the new one for 3 weeks, so is it ever too late for me to get the piggy? Because I really want to get her a friend when they have a bigger cage. Thanks
