Hi! Currently I just have my single guinea pig and have not partnered him yet. I got him from a family friend who was breeding and couldn't take his brother as well because he was claimed. Around 7-8 weeks after my guinea pig and his brother were born there was another single birth from the same parents. I took my baby at 6 weeks and have had him since, while the family that took his twin also claimed the single baby from the second litter. Recently they posted that they are trying to re-home both and I am interested in taking them. All three are males younger than a year old but I am a first time owner right now and unsure how introducing them would go.
