Clover & Calla are baby sisters with tender spirits and they debut for adoption today at Nevada SPCA (www.nevadaspca.org). The girls are Crested guinea pig mixes with tortoiseshell and chocolate coloring, almost 2 months of age. Clover & Calla are well-adjusted and enjoy people, thanks to wonderful loving care in a foster home. (We rescued their pregnant mother, who has since been adopted.) Clover & Call need to be adopted together for lifelong companionship.
