Cavy   arrow


Cavies, more commonly known as guinea pigs, are easy-to-care-for household pets and are a great way for young people of all ages to get involved in livestock projects in 4-H. In the 4-H Cavy Project, enrolled members will learn how to perform health checks on their animals, how to care for their animal through nutrition and other practices, how to show their animal, and gain general knowledge about the diverse breeds that make up the cavy family.  All animals and family pets are welcome in this project.  Come ready to learn more about your animal/s and share in the joy that is cavy ownership!

Project Learning Resources:
