Don't give them to Petco. They are most likley to go to any old home who won't take care of them. Selling them through the paper is a better idea because you can meet the person in person and really see if they are expierenced with degus. Ask them questions so you know where they degus will live, what they are fed, and most importantly if they will be loved. People sometimes go to Petco to buy toddlers/minors a pet to show responsiblity and the animal ends up being forgotten and uncared for. Please reconsider giving them to Petco and rather sell them through the paper.
