My vets office in Drexel Hill, PA took in 3 female guinea pigs, approximately 1 1/2 years old. All three have been patients of my vet so they are in good health. One just had an abscess from her ear removed. All were surrendered for the same reason, "Bought for a young child/teenager who doesn't have the time to care for them, play with them". They may have already found a home for the 2 that are bonded but there is still a single female that needs a home. I don't have photos but if they are still there when I work at the vet on Saturday I'll add. When they get adopted I'll update this.
I would gladly take them but I have 3 males and no room for a separate cage for females.
