Guinea Pig For Adoption. We have a sweet-natured almost 2 year-old male guinea pig that needs a new home. Our kids have allergies which mean they cannot give the guinea pig the love and attention he needs. We will include all the gear you need: a large cage, food bowl, water bottle, house, nail clipper, etc. We would really like this little guy to go to a good home.
